Explanation of the Difference Between Wires and Cables and Wire Harnesses

1 Wire and cable are used to transmit electrical (magnetic) energy, information and wire products for electromagnetic energy conversion. 

Broad wire and cable are also referred to as cables. 

Narrow cable refers to insulated cable, which can be defined as a collection consisting of the following parts: One or more insulated cores and their respective cladding layers, a total protective layer, and an outer sheath, the cable may have additional uninsulated conductors. 

A wired product used to transmit electromagnetic energy, information, and electromagnetic energy conversion.

Broad wire and cable are also referred to as cables, and narrow cables refer to insulated cables. 

It can be defined as an assembly consisting of one or more insulated cores, and each of the possible cladding layers, the total protective layer, and the outer sheath, and the cable may have additional uninsulated conductors.

The main features of this type of product are a wide variety of specifications, a wide application range, more than 1kV and below, and new products such as fire-resistant cables, flame-retardant cables, low-smoke halogen-free/low Smoke low halogen cable, termite prevention, mouse cable, oil/cold resistant/temperature resistant/wear resistant cable, medical, agricultural, mining cable, thin wall wire, etc.

2 The wiring harness provides a total of service equipment for a certain load sources group, such as a trunk line, a switching device, a control system, and the like. 

The basic research content of traffic theory is to study the relationship between traffic volume, call loss, and wire harness capacity. 

Therefore, a wire harness is an important basic concept in traffic theory.

The load source is the service object of the wire harness, and usually refers to the user equipment; in a broad sense, the upper-level device is the load source of the next-level device. 

The harness has a capacity of V and serves N load sources. 

Any load source that makes a call can consume one of the idle service devices in the harness.
