FFC wiring harness provides a total of service equipment for a certain load source group, such as trunk lines, switching devices, control systems, etc. The basic research content of traffic theory is to study the relationship between traffic volume, call loss and FFC wiring harness capacity. FFC wiring harness is an important basic concept in traffic theory.

Composition of FFC wiring harness

In order to facilitate installation and maintenance and ensure that the electrical equipment can work under the worst conditions, the different specifications and different colors of the electrical equipment used in the whole car are rationally arranged to integrate them into one, and the wires are bundled with insulating materials, which is complete and reliable.

2. Normal selection of wire cross-sectional area and color label

1) Correct selection of wire cross-sectional area

The electrical equipment on the car selects the cross-sectional area of the wires used according to the size of the load current. Electrical equipment that works for a long time can choose 60% of the actual carrying current of the wire; Electrical equipment that works for a short time can use 60%-100% of the actual carrying capacity of the wire.

2) Wire color label selection

In order to facilitate identification and maintenance, the wires in the electric FFC harness are of different colors.

In order to mark the convenience in the circuit diagram, the color of the wire is represented by a letter, and the color represented by it is noted in each circuit diagram.
