Automotive wire, also known as low-voltage wire, it is not the same as ordinary household wires. Ordinary household wire is copper single core wire, a certain hardness. The car wires are copper multi-core cord, some soft lines like hair, a few or even dozens of soft copper wire wrapped in plastic insulated tube (PVC), soft and not easy to break.

Due to the particularity of the automotive industry, automobile wiring harness manufacturing process than other ordinary wiring harness is more special.

The wiring harness is the wiring part connecting the electrical equipment in the circuit, and is composed of insulation sheath, terminal block, wire and insulation dressing material.

First, the composition of the wiring harness

Wire harness

In order to facilitate the installation and maintenance, to ensure that electrical equipment can work in the most harsh conditions, the whole car electrical equipment used in different specifications, different colors of the wire through a reasonable arrangement, will be integrated, and insulated wire bundles Into a bundle, so that both complete and reliable.

2. Wire cross-sectional area and the color of the normal choice

1) the correct choice of wire cross-sectional area

The electrical equipment on the vehicle selects the cross-sectional area of the wire used according to the size of the load current. Long-term work of electrical equipment can choose the actual carrying capacity of 60% of the wire; short-term work of electrical equipment available current capacity of 60% -100% of the current.

2) wire color selection

In order to facilitate identification and maintenance, wire in the wire harness uses a different color.

In order to facilitate the call in the circuit diagram, the color of the wire are shown in letters, the representative of the color in the circuit map are notes.
