Flashcards

Wire Bundle

A group of wires or cables that are bound together to create a single, organized unit. It is an interchangeable term with "cable harness."

Cable Harness

A structured assembly of wires or cables that are bundled and secured together with specialized components, such as tie wraps, clamps, and sleeves. They are used in vehicles and machinery to manage and protect wiring.

Purpose of Cable Harness

Cable harnesses in automobiles and construction machinery reduce the risk of electrical shorts and damage, protect wires from abrasion, and simplify maintenance and repair.

What Material Binds Cables?

Extruded string, sometimes called 'tying string', is used to bind cables together in a cable harness. It helps to secure the wiring and prevent movement or separation.
