Where Are Wiring Harnesses and Cable Assemblies Used?

In complex electrical systems, there are a number of devices that keep sensitive wires and cables protected and organized. An example of such components are wiring harnesses or cable assemblies, which serve to organize, consolidate, and protect electrical conductors. As wiring harnesses are generally customized according to application, they can dramatically improve a system’s efficiency.

A wiring harness is simply a bundle of cables and wires, alongside the components utilized to sheathe, support, and organize them. These elements include tapes, sleeves, and ties, all of which keep cables in the optimum position for transmission. As previously mentioned, wiring harnesses are designed based on the electrical requirements and geometrical parameters of the job at hand, and they are used to simplify the connection to larger components.

Essentially, wiring harnesses solve many of the challenges that come along with electrical systems. By combining many individual wiring elements, they make it easier to connect and assemble complex systems. Moreover, wiring harnesses provide additional protection to wires and cables by preventing unwanted flexion and insulating bundles from the environment.

Together, wiring harnesses and cable assemblies are utilized across a wide range of industries. In general, most manufacturers find that combining electrical elements in a harness is not only a cost-effective way of improving performance but also a simple way to install and organize electrical systems. For instance, these elements are often found in sectors ranging from aerospace to residential wiring applications.

Applications Across Varying Fields

In the aerospace realm, wiring harnesses allow power transmission in aircraft engines, data transmission from satellites, and more. Similarly, the automotive sector benefits from wiring harnesses and cable assemblies as they are indispensable for saving space and ensuring wires fit around mechanical components. Some of the most common applications include lights, turn signals, displays, and various others. In hospitals, wiring harnesses enable clinicians to establish reliable connections, often being a matter of life and death in many instances. Furthermore, telecommunication systems take advantage of wiring harnesses and cable assemblies to save space and facilitate identification as they often deal with tens to thousands of cables, as well as multiple modems, routers, and similar communication equipment. Other common applications include IT, robotics and automation, construction, and manufacturing.

Benefits of Wiring Harnesses and Cable Assemblies

One of the main benefits of using wiring harnesses and cable assemblies is the decreased installation time and safety they provide. As assemblies group cables in an efficient manner, installation is quick even in large or complex systems. Such organization makes it easier to identify and locate the appropriate components. In terms of safety, harnesses are often equipped with structural supports, insulation, and shielding to protect against dangerous shorts. More than that, they keep wires in place, avoiding accidents in the workplace.
