Cable assembly and wiring harness

Cable assemblies and wiring harnesses are often confused by the same thing.
This confusion is understandable, as many professionals use these terms interchangeably, and the products themselves have very similar basic functions. However, these products and their purposes are very different from each other, which means that definitions are needed to help people get the products they need. Here is a brief description of the cable assembly and wiring harness, as well as the worldwide usage of each product.

Cable assembly and wiring harness:
Before discussing the significant differences between cable assemblies and wiring harnesses, it is important to note the differences between wires and cables, because although these terms are completely different, they can be used interchangeably. Essentially, a wire is a bundle of conductive material, such as aluminum or copper. A cable, by contrast, is two or more wires running together. They are usually glued or woven together, which is why you see cables that look like a bundle of tangled wires.
Wiring harness.
Basically, a harness is a simple outer sheath that covers a number of wires or cables. It is usually made of a thermoplastic or thermosetting material that helps protect the wire from environmental effects. In most cases, wiring harnesses tie together cables and wires that are already protected by their own external sheaths. This means that you can open the wiring harness and look at multiple cables with their respective cladding, but they are all in one wiring harness.

Wiring harness is a low-cost electrical solution that is best suited to keeping electrical systems in good order. By tying the wires and cables together, engineers and electrical contractors can keep their wiring systems in good order. Because wiring harnesses are usually a low-cost organizing tool, they often do not protect the internal wiring from constant friction, temperature fluctuations, or other factors that can cause damage to the wiring inside the wiring harness.

A cable assembly is a set of wires or cables covered with a stronger external product. Typically, they are made of heavy materials, including shrink-wrapped thermoplastic, thermoplastic rubber, or vinyl. These components function like wiring harnesses, including keeping wires and cables organized, but are designed for completely different environments.


Cable assemblies are designed for specific environmental factors, including the size of the area to be used and the type of environmental factors that may be encountered. Therefore, cable assemblies can come in a variety of shapes and sizes, and can shield internal wires and cables from heat, friction, moisture, wear, compression, and other hazards.
So what’s the difference between a harness and a cable assembly? Well, each is used in a different context. Wiring harnesses provide a low-cost solution for keeping wires organized, while cable assemblies ensure the safety of all products in the most extreme situations.
