Cable Harness Systems and Manufacturers

Many industries are huge users of cable harness systems and products to ensure that their applications run appropriately. Industries such as aviation, automation, oil, food & beverage, robotics and renewable energy all rely heavily on many of the systems offered by cable manufacturers.

Cable harnessing are very effective at maximising space, while maintaining a great level of protection to the individual cables that are harnessed inside of the housing. In the case of aircraft, there can often be miles of cabling that must be organised inside of the plane, which would be an extremely confusing process without the use of cable harness systems and techniques.

Thanks to the ease of assembly, it is possible to manufacture bespoke cable assemblies for nearly any electrical application. They can come in different lengths, diameters, wire ranges, and in various different resistant materials. The range of outer sheaths can combat UV rays, oil, heat, fire, moisture and cold, meaning that the cable assembly can be used in a huge number of different environments.

Many different cable assemblies are made of 100% recyclable materials and can be environmentally friendly. On top of this, there a wide range choice of terminals and connectors that can be attached easily, making it great for the input and output of electrical current, data and control.

Cable harnesses can vary from application to application. This means there is a huge demand for both standardised, ‘out the box’ harness systems, as well as custom versions that are made by cable harness manufacturers. Wire assemblies are generally calculated or individually specified to applications electrical and geometric requirement. This is always done using advanced computer software that ensures perfect measurements and to reduce human error. Stringent and methodical control is kept over the process to ensure assemblies high quality where the individual wires are cut to specified requirements and bound together to produce the cable harness.

Each aspect of a cable harness is considered before the final product is constructed. The environment in which a cable harness system can be used can vary greatly, from some needing to work at cold and high altitude conditions, whereas other may have handle degradation caused by salt in the air, or UV rays from the sun.

Expansion Joints

Metal Expansion Joints
Expansion joints systems are an interesting alternative for pipes and pipelines. Expansion Joints such as these are able to be used in industries such as the oil, paper as well as the petrochemical industries, as well as a lot of other areas.

These are very diverse creations, and quite widely available. They are typically made to standard dimensions, and are able to reach from 1 to 100 metres in diameter and can withstand temperatures from -150°C to 2200°C. They can also resist a full vacuum or 2000 psig.

The market has been totally changed by the introduction of fabric expansion joints, because engineers have a new way to deal with thermal expansion as well as corrosive and abrasive problems.

These fabric joints are able to be used in applications for things such as turbines. Different fabric membranes and designs make it easy for joints to be used for turbines exhaust applications. Distinctive problems arise in the form of GTX, which are difficult applications which present challenges concerning performance and resistance over time. With the aid of fabric joints this can be solved much more easily.

Pipeline systems often use metal bellows to connect pumps and vessels. The folds in the design allows for superior movement in the axial, lateral and angular dimensions. To increase flexibility, other trimmings such as ties, pivots along with other trimmings. These devices have a lifespan, which depends on the shape, material along with the degree to which the connection must be able to bend to.

Metal expansion joints are crucial for pipeline technology as they are needed to counterbalance changes in length, this occurs in pipelines from changes in temperature, aside from this vibrations from pumps engines compressor or turbines are absorbed. Metal expansion joint are a cost effective option to increase the productive life of the pipeline system, making it run better and live longer. Designed to live as long as the system, the metal bellows reduce any sealing problems and the large space needed when dealing with other forms of expansion equipment.

FCCU Expansion joints are available; these need to withstand high temperatures and intense pressures, as well as aggressive environments and significant movements.
Expansion joints are great components and well used for the right application can make things incredibly easier and more efficient.

The importance of Wireline logging in the Oil and Gas Industry


The oil and gas industry relies heavily on wireline logging, to obtain a continuous record of a rock formation and its properties. The results then allow them to find out further properties, such as hydrocarbon saturation and formation pressure, which will make further drilling and production decisions a lot easier looking ahead.

Wireline logging is performed by lowering a ‘logging tool’ on the end of a wire line into an oil well (or borehole) and recording petro physical properties using a variety of sensors. Logging tools that have been developed over years measure the electrical, acoustic, radioactive, electromagnetic, nuclear magnetic resonance and many other properties of rocks and their contained fluids, allowing them to evaluate before looking ahead to reap the advantages.

Data is recorded at surface or in the actual hole. In an electronic data format that can then be either be recorded through printing or electronic presentation called a “well log” that is then provided to the client. An electronic copy of the raw data is made up and well logging operations can either be performed during the drilling process. This provides real time information about the formations being penetrated by the borehole, or once the well has reached a total depth and the whole depth of the borehole is able to be logged.

There are a variety of different types of wireline logs, which are often categorized by singling out their functions or alternatively by the technology that they use. “Open hole logs” are run before the oil or gas well is lined with pipe or cased. “Cased hole logs” are run after the well is lined with casing or production pipe. Wireline logs can also be divided based on what physical properties they measure, making up the different categorization methods.

Robertson Geologging are developers of slim-hole digital borehole logging systems and techniques and are also one of the largest global suppliers for slim-hole and bore-hole logging equipment.
