Deconstructing Cable Assemblies: A Primer For First Time Buyers

When faced with your first purchase of cable assemblies, you can be certain you will have a few questions. There are so many options for the customization of these structures, that it can be difficult knowing where to begin. Whether you choose to select a pre-manufactured, en masse assembly or whether you opt for a customized option, you need to understand the function, purpose and construction of these prevalent objects.


Cable assemblies are generally comprised of inner conductors, which transmit the signals within the wires to other components. The wires are then encapsulated in an insulating material. This layer should be strong and all-encompassing. The insulation prevents the wire’s signal from escaping. Some structures include a shield, comprised of various material, depending on the function of the wire, to prevent outside interference with the signal. The final, outer layer consists of a jacket, which protects the entire structure from outside elements. Connectors then shape, connect and guide the wires to other parts.

Variations Based on Function

There are many uses for different cables. Some uses are generic and follow a standard procedure. For the very basic elements, a pre-manufactured assembly can be wise. But for industries that require cable assemblies for more specified purposes, a more customized approach is preferable and even necessary.

These set-ups vary depending upon the different needs of the installation, as well as the different environments in which the cables will be placed. For instance, for mechanical processes that are installed on oil rigs at sea, many cable systems must be treated with a galvanization process, protecting the wires from rust due to saltwater. Some assemblies require more connectors, fastening the system in place to brace against heavy winds. Heavy vibrations and extreme temperatures are also factors to consider when assembling the cable.

Working with a Company

When utilizing a company’s process of customization of cables, one should be aware of a few key essentials. First, electrical structures are almost always serious, with a malfunction resulting in a loss of revenue and sometimes carrying a risk of injury or even death in extreme cases. It is important to find a company that adheres to the industry’s highest standards, as evidenced by a company’s certifications. Always take a look at whether the company is registered nationally and is a part of the UL. Additionally, you will want to feel at ease with a representative assigned to help you throughout the process of customizing cable assemblies. Request a representative who is familiar with your field.
