Product details
The circuit group provides the overall 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 harness capacity. Therefore, harness is an important basic concept in traffic theory.
In order to facilitate installation and maintenance, and ensure that the electrical equipment can work under the worst conditions, the wires of different specifications and colors used by the electrical equipment of the whole vehicle are integrated through reasonable arrangement, and the wires are bundled with insulating materials, which is both complete and reliable.
2. Normal selection of wire sectional area and color code
1) Correct selection of wire sectional area
The electrical equipment on the vehicle selects the cross-sectional area of the wires used according to the load current. For electrical equipment working for a long time, 60% of the actual current carrying capacity of the wire can be selected; Electrical equipment working for 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 wire harness are of different colors.
For the convenience of marking in the circuit diagram, the colors of the wires are all indicated by letters, and the colors represented by them are noted in each circuit diagram.
