NYY and NYCY Cables

NYY and NYCY cables are black PVC jacketed, power and control cables with single and multi-wire conductors. NYCY and NYY cables are designed for energy supply in various locations, such as cable ducts, power stations and distribution boards as well as many industrial applications.

Both NYY and NYCY cables can be used in brickwork and in concrete; the NYY cables can be installed in open air, underground, in water and indoors. The cables are available in both single and multi core variants. They are sometimes referred to as general mains power cables in the industry.

The cables have a conductor of bare copper wires, with PVC core insulation and PVC based outer sheath.

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.
