A Brief Explanation Of Cable Assembly VS Wire Harness

- Dec 06, 2018-

(1)Wire VS Cable

Before knowing the difference between them, you must know about wire and cable. A wire is a strand of material that conducts electricity, such as aluminium or copper. A cable, by contrast, is two or more wires that run together. They're often bonded or braided together, which is why you see cables that look like bunches of intertwined wires.

(2)What is the wire harness?

A simple exterior sheath(usually made of thermoplastic or thermoset material) that covers some wires or cables. For the most part, wire harnesses bundle up cables and wires that are already protected by their own exterior sheaths. That means you could open up a wire harness and see multiple cables with their own coverings, but they're all in a single wire harness.


Wire harnesses are a low-cost electrical solution that's best for keeping electrical systems organized. Since wire harnesses are often a low-cost organizational tool, they aren't generally able to protect the wires inside from constant friction, temperature swings, or other factors that could cause damage to the wires inside the harness.

(3)What is cable assembly?

A cable assembly is a group of wires or cables covered by a much more intensive exterior product. Normally it will add with connectors for fixed and protecting. The function of those assemblies, including keeping wires and cables organized, but are designed for entirely different environments, such as from heat, friction, moisture, abrasion, compression, and other hazards.


(4)What's the difference?

Each is used in different environments. Wire harnesses offer a low-cost solution for keeping wires organized, while cable assemblies keep all of the products safe in the most extreme circumstances.
