LED Tube Lighting

There has been a rapid incline in LED tube lighting technology over the previous decade. There are now many products available that are cost effective, energy efficient and more environmentally friendly than regular incandescent or fluorescent lighting - they can use up to 95% less energy than an equivalent method of lighting.

The other main advantages of using LED lights include improved robustness, less heat loss, longer lifetime, faster switching and the versatility of their application. LED lighting often offers ideal replacements to less efficient, corresponding products.

Direct replacements are available for the standard T8 tube but with the added extras of offering longer life and lower maintenance. These will generally provide energy savings of around 75% in comparison with its counterpart. The use of this technology allows a fresh approach to conventional norms of lighting. It will be interesting to see how the future usage changes and develops.

The LED wall washer is also available. With great light progression due to the advanced LED technology – this is an ideal product to replace a standard electric wall washer to illuminate hotels, stages, buildings and artwork. It uniformed light distribution gives you natural and non-intrusive lighting at a fraction of the electricity cost.

It’s not very often that you get to call a ceiling panel stylish, but the architectural design on of an LED wall panel is a truly revolutionary product. It allows an optimal distribution of light and can offer you great lighting ambience. It creates light that results in an effective and attractive display, and will make your environment more comfortable. These are being used more and more by architects and in social housing for both aesthetic benefit and long term energy cost savings.

During the previous ten years, the application possibilities of LED’s have multiplied greatly. It is now a viable, reliable, safe, stylish and cost effective form of lighting, and as we look to a greener future, it is very likely that LED technology will continue to develop and will become a common fixture in both the home and in industry

Low Smoke Halogen Free Cable

As safety takes paramount place in today’s world, contractors and builders are turning their attention to products that are safer, more co-friendly and non-hazardous such as LSHF cable. Low smoke halogen free cable offers a great alternative to PVC cable when installing in areas or environments where there is a higher threat of fire which poses risk to human life, animal life or if there is a high volume of costly equipment.

low smoke halogen free cable
The improved material emits a much lower percentage of smoke and contains no halogens – therefore not producing the toxic gases that PVC cabling typically gives off when in contact with fire or very high heat. If a plastic of halogen content comes into contact with flames, it releases hydrogen chloride, and when this chemical comes into contact with H2O it turns into injurious hydrochloric acid. Halogen free cable has been designed to combat this and to protect the health of both humans and animals in highly populated areas, but also to safeguard expensive equipment, servers and data centres. Vitally important computing equipment that comes into contact with smoke can cost a company hundreds of thousands of pounds.

A low smoke halogen-free cable, also known as low smoke zero halogen cable, is generally made from a thermoplastic or a thermoset material, that under conditions of fire will give off very limited smoke and no halogen. A cable has to have less than 0.5% halogen to be deemed halogen free. The halogen content is of 3 tests that are used to standardise LSHF cable, with the other two being tests on their smoke density and flame transmission. , All tests adhere to the industry standards set by the IEC (International Electrotechnical Commission) and the VDE (Verband der Elektrotechnik) . 

Halogen free cable is being used more and more in a variety of different applications as contractors and individuals demand safer and less hazardous surroundings. Where there is risk to property, equipment or to human life LSHF cable is always used. In areas, buildings or vehicles in which there is low ventilation it is imperative to use the correct standard of cable. It plays an important part in many fields such as the transport industry and the hospitality and entertainment sector.

Below are some of the commonly found low smoke halogen free cables;

•    OLFLEX 120 H
•    OLFLEX 120 CH
•    OLFLEX CLASSIC 130 H BK 0,6/1kV

What is Hydrostatic Testing?

Hydrostatic hose testing is one of the most common methods for testing hoses, pipes and other pressured vessels. If the test is successful, it then qualifies the product to be used under a specific stress or environment and for a specified length of time.

The market for scientifically proven pipes, hoses and assemblies is extremely competitive. These products need to bear up against stringent and methodical testing over a long period to determine their strengths and weaknesses.

Hydrostatic testing is typically conducted under the specifications of the hydrostatic testing supplier, the industry standards or the customer. Generally, the testing is carried out inside a sealed and closed system to minimise any errors and give ultra-precise readings. A regular test procedure is to fill a container with a liquid that has incompressible properties, usually water, dyed water or oil, and then to place the vessel (i.e. the hose) inside the container and apply pressure inside the closed system. The applied internal pressure and the duration are normally always fixed.

This known pressure is typically a great amount larger than the usual specified operating pressure of a device – generally around 150%. As the pressure is applied it causes the vessel to expand and both the permanent and the total pressure expansion are carefully measured.

These measurements, together with internal and external visual checks, are used to ascertain whether or not a pressurised vessel can be used safely. This also gives an understanding of the lifetime of the container – this is typically determined by the exemption or specification to which a pressure vessel has been manufactured. A product must be condemned if its structural integrity is abnormal, is degraded or if it fails.

This is an extremely important testing procedure to identify how safe and/or durable a device is under pressure and also to identify any leaks that a vessel may be prone to developing. These hoses and pipes can be used to transport dangerous or hazardous substances – areas where there is no room for errors or manufacturing floors.

All quality hose testing and hydrostatic testing companies keep computerised records of their products and will monitor each unit throughout the course of its lifetime. This ensures that mistakes are kept to a minimum and if any unexpected problem occurs the computerised systems will quickly notify the user or the manufacturer.

Industrial Hoses

Industrial Hoses are components used to transfer liquid for one place to another, these are usually made to be resistant, durable and flexible. They are constructed differently depending on the application, with a variety of materials such as rubber, PVC, hydraulic, and composite hose. These are typically joined by hose connectors, or hose couplings, these are positioned at the ends of the hose and are used to connect the end of the hose to another hose, or an actual appliance.

Industrial hoses are used in a range of Industries including Aircraft, Chemical, Marine, Industrial, Petroleum to things like Fire engine suction, Water, Jetting, Dock, and Dredge. Industrial hoses are for the most part designed to be able to handle intense conditions that are a part of the territory of such industries, these include things such as high pressures, extreme temperatures, heavy tensions, and contact with chemicals. These hoses are built to deal with some of, if not all of these conditions.

Braid and coil sheaths work to protect hoses against any mechanical tension, which includes pinching, chafing and impact. High and low temperatures that are met have to be prepared for with the correct chemical composition. The hose must also be able to deal with chemicals that the hose is subjected to and for this reason needs resistance. This resists any damage that can be caused by acid and alkaline mediums as well as any done by hydraulic and lubricating oils. The fittings also need to have resistances, after all it would not do to have a weak link between the hoses. Because of the varying sizes of hoses there are also a range of connectors to join them, these include Bellows Connectors, Bin activator Seal connectors, and Flexible fabric connectors, which all serve different purposes.

It is important that all hoses are regularly tested because they often transport harmful chemicals so if they are not tested for quality then they could cause severe health and environmental issues.

Low Smoke Zero Halogen Cables

Halogens are a group of elements of the periodic table. This group includes fluorine, chlorine, bromine, iodine and astatine.

You may not know it, but halogens are used every day. Fluoride is found in most toothpaste, chlorine is used to keep pools clean and iodine is found in medicine cabinets everywhere. Beside the simple things we use them for; there are also several other incredible things for which halogens are useful, including cable jackets as fire resistance using PVC.

However these chemicals can cause health problems. Although halogen compounds work to keep important components from catching fire, they may release hazardous gasses if they reach volatile temperatures. Carcinogenic gasses such as Polychlorinated Biphenyls (PCBs), Polycyclic Aromatic Hydrocarbons PAHS and dioxins are all dangerous chemicals which can be produced from the ignition of the cables, not only this, but if in contact with water, they can condense into dangerous caustic acids, for example hydrochloric acid. However, there is an alternative; Low Smoke Zero Halogen cables (LSZH).

As you may have deduced from the name, these cables are ideal because they only produce a very small amount of smoke when igniting, and no toxic gasses which is so much safer than the hazardous traditional method. LSZH also perfectly complies with European and North American safety and environmental regulations. LSZH are widely used in poorly ventilated areas, such as aircraft or railcars, where poisonous gas would be most fatal. LSZH is becoming more and more widely used and is now even a requirement in places where people’s lives are most at risk of such a thing. Aside from this, LSZH cables are also often lighter, so the overall weight of cable systems is reduced, and because they don’t release dangerous chemicals, they also cause less harm to the environment. Overall LSZH is the superior alternative.

Cable Glands

There is an ever growing range of cable glands within the cable industry, with cables glands in the home and office industry as well as the others across the industry becoming more and more developed across the globe. These glands form the basic wire management products which are very functional and useful across various different industries and home needs. Although there may be other types or management products available on the market, such as grommets, panel plugs, bushing, tapes and tubing, connector caps, plugs, clamps and clips as well as many others. Cable glands are usually a very popular choice due to the suitability to its purpose.

Throughout the industry, there are often new lines of cable glands produced and brought into the market, developed to continue to cater to the changing needs of consumers within relevant industries. There are many different designs of cable glands in the market, but the industrial recommendation suggests that wired glands that have the smallest maximum range of clamping for the required or desired application. It is important to make sure that the glands ensure best functionality as the join the availability of rubber and plastic grommets in protecting wires and grommets against damage from sharp edges.

Cable glands are available in specific models which are suited to specific applications. Right angle wires come in black UL nylon material which is highly recommended with this type of gland. NPT glands can withstand a wide range of temperature from -40 degree F to as high as 221 degrees F – with an intermittent temperature as high as 300 degrees F. Special glands such as this have an IP 68 rated protection of 5 bars that means it can perform very well against dust and water environments. They can be very resistant and durable against strain. However, it is not uncommon for right angle glands such as these to have extra components that come separate.

These special wire glands are designed with variable clamping ranges that will prove to be advantageous when fitting into a wider diameter range. Metric glands are sometime popular within the market, which are usually black UL nylon materials that can also withstand the same wide range temperature as the right angle wire glands.

Solar Cables for Wind Turbines

Wind is caused as warm air rises and cooler air rushes in to replace it. It is the sun which heats the air, so many refer to wind energy as a form of solar power. It’s been well known for centuries that wind energy can be used to generate power.

A wind turbine harnesses the energy in the wind; small systems can be used to power electrical appliances and lights in a usual household. With a wind turbine, the larger the blades, the more energy generated. The blades are used to catch the wind, causing them to rotate and generate electricity. The more wind, the more electricity produced.

Groups of wind turbines are often build in locations with strong winds, such as out at sea or in valleys. These groups of turbines are known as wind farms, and are typically used for commercial production of electricity. This type of wind turbine is usually three bladed and has computer controlled motors which point them into the direction of the wind. These turbines can have tip speeds of over 200mph, high efficiency and low torque ripple, which contribute to reliability.

Commercial wind turbines are light grey in colour and blend in with the clouds. Their presence can sometimes upset local residents when built in the countryside.

The blades can range from 20 to over 40 meters in length, with the steel towers standing up to 90 meters high. It is possible to connect your own small wind system to the National Grid and sell any energy produced to an electrical supply company.

These large turbines require industrial cables, Lapp Group supplies many of these, including specialist Solar Cables.

Hydraulic Testing & Hose Connectors

Advancements in Hydraulic Testing, Assembles and Fittings

Hydraulic hoses are used in wide variety of markets in industry all around the planet. Industrial hoses are used to transfer high pressure gas or fluid in machinery and industrial plant processes. The hazards that come with leaks are great, so the safety mechanisms required are put through stringent testing procedures.

All of the auxiliary adaptors, staple couplings, valves and other hose fittings are fully tested for endurance and flexibility.

Staple Adaptors

There are many industrial hose connectors in the market; most notable is the hydraulic hose staple adaptor. A staple adaptor is effectively a mechanism which connects two hoses together by the ends, these are used for high pressure fluid transfer in hazardous environments (like underground).

The connection often needs to be held together under extreme pressure, in order to do this, staple adaptors utilise a staple lock which is a piece of steel shaped like a staple u-bend which is fed into both the male & female couplings of the hydraulic hose.

Rotary Staple Couplings

Large scale bore mining needs hydraulic hoses which are able to withstand high pressure fluid and gas transfer while moving freely due to the vibrations caused by the high stress environment. For such applications rotary staple couplings are used, these reduce stress by allowing the hose assembly to move freely while in operation, yet retain a high pressure locking mechanism.

Hydraulic Hose Assembly Protection

The hazardous environments that hydraulic hose assemblies are required to work in demand protection solutions which will protect the outer surface of the hoses. Now days, there are a number of protective coatings which are resistant to abrasion and extreme temperature. Protection can be used for both single and bundled hoses.

This type of hose protection is ideal for oil spill and electrical cabling, there are grades of protective silicon coated sleeves that are fire resistant.

Hose Assemblies

Custom made hose assemblies for specific locations around the world are common due to the varying environments which hydraulic hoses are required to work in. There are certain product lines which are generic, but many manufactures will produce bespoke hose assembly solutions suited to their requirements.

Rubber Cables

Standard industrial rubber cables are ideal for outdoor use, in damp and wet conditions. Some can operate while submersed in water. A rubber cable needs to have a tough sheath capable of withstanding moderate use in mechanical environments under stress.

Different types of rubber cable are used in different applications, the H05RR-F cable is for lightweight hand and workshop tools, whereas some like the H07RN-F cable is more suited for high levels of stress in heavy duty equipment.

Examples of the rubber cable are the H05RR-F, a lightweight rubber sheathed cable, the NSSHOU cable; which is a mechanically robust rubber sheathed mining cable, and the H07ZZ-F cable; a Low Smoke Halogen Free cable.

Authorities are recommending the use of Halogen free cables throughout the world, as cables can produce hydrogen chloride gas if burnt that forms hydrochloric acid when in contact with water. As the rubber cable is used in many public areas and buildings there are certain safety requirements that installers must follow.

Low Smoke Halogen Free Cables

Low smoke halogen free cables have increased in demand largely, as public safety has become a more prominent issue. Contractors have been advised to use materials which aren’t hazardous to health when burnt, mostly when installing cables in public areas and building. Low smoke halogen free cables are the ideal choice, as they reduce the amount of toxic gas emitted during combustion.

During a fire, the smoke is well known to be the biggest killer. Using non-hazardous materials helps reduce the risk if a fire happens.

Proper low smoke halogen free cables are usually referred to as Low Smoke Zero Halogen cables; there is often confusion between which cables are suitable and the safest to use. Many cables are referred to as “low fume”, but can often contain halogen, which when burnt releases hydrogen chloride. When hydrogen chloride comes into contact with water, it forms hydrochloric acid which is toxic to human skin.

Industrial Connectors

Industrial Connectors for cables are the solution in applications where reliability, durability and flexibility are important. Cable connectors help connect different types of cable to different appliances and devices. There are a range of cable connectors; including rectangular, circular and pin and sleeve styles. Connector enclosures provide a range of environmental protection.

Rectangular connectors offer a system of housing, inserts and contacts that come together, forming robust and secure solutions that are easy to assemble. Examples of rectangular connectors include for EPIC MC Modular and EPIC H-B Housings.

Circular connectors are single connectors for use on servo motors and servo harnessing. Available as couplers, these connectors can be used for simple cable to cable and cable to machine applications. Some circular connectors, such as the EPIC CIRCON LS1 Circular Connectors come with an integrated EMC screen termination.

Pin and Sleeve connectors are ideal for use in light industrial wiring applications.

Solar Panels Cheshire

There are many advantages to using solar panels, and although solar energy may be relatively new, it could easily become the most important energy source in the future. Solar energy is a renewable energy source, meaning there is no danger of its energy reserves running out.

Solar power is non-polluting. Unlike fossil fuels, using solar power does not emit any greenhouse gases – there is also no danger of it harming ecosystems through spill or degrading. These are probably the most important advantage of solar power and provides good reasons to use the technology.

The energy and heat from the sun is free, once solar panels are set up there are no extra costs to use the energy. The solar cells require very little maintenance, just the odd bit of cleaning to keep them at full output.

Solar power is proving incredibly versatile, providing power for cars, water heaters, buildings and satellites. In some remote locations, solar power is the only option for generating power.

Solar Panels have become increasingly popular are also a very worthwhile investment, as they help save on energy bills and also increase the value of a home.

There are some disadvantages of solar panels, such as the amount of sun light available in different parts of the world is considerably less; and the price of solar panels is still fairly expensive. In the future, the continued development of solar panels will see their effectiveness increase and their prices to fall, making them a real alternative for everyone.

Hose Couplings

Hose couplings are used when connecting (or coupling) two hoses together, or to connect a hose to a tap or to an appliance. Hose couplings are typically made from steel, brass, aluminum or plastic.

There are many different types of hose couplings. One example is the Air King universal air house coupling, which is made from malleable iron and usually found on pneumatic tools such as jackhammers.

Another type of hose coupling is the Cam and groove, which is a quick connect fluid transfer hose coupling. These couplings are usually found in petroleum of chemical applications.

On of the most successful hose couplings is the Hozelock, which is a plastic, click-on style push fit hose end connector. This type of hose coupling came around in the 1950s and was developed to replace metal hose end connectors in coal mines (the metal hose couplings could cause sparks, creating the possibility of a methane gas explosion). The plastic house couplings are now used universally by gardeners all around the world with the simple garden hose.
