The wiring harness is the wiring component that connects the electrical equipment in the circuit. It is composed of insulating sheath, terminal blocks, wires and insulating wrapping materials.
1. Electrical wiring harness
In order to facilitate installation and maintenance, to ensure that electrical equipment can work under the worst conditions. Integrate the wires of different specifications and colors used in the electrical equipment of the entire vehicle into one through a reasonable arrangement. And use insulating materials to bundle the wires into bundles, which is complete and reliable.
2. Normal selection of wire cross-sectional area and color code
1) Correct choice of wire cross-sectional area
The electrical equipment on the car selects the cross-sectional area of the wire used according to the size of the load current. For electrical equipment that works for a long time, 60% of the actual current carrying capacity of the wire can be used;
Electrical equipment that works in a short time can use 60%-100% of the actual current carrying capacity of the wire.
2) Selection of wire color code
In order to facilitate identification and maintenance, the wires in the wiring harness are in different colors.
For the convenience of labeling in the circuit diagram, the colors of the wires are all indicated by letters, and the colors represented are noted in each circuit diagram.
