Why do cars need wiring harnesses?

What is the wiring harness of a car? The car is very large, with an average length of about 4 meters. Nevertheless, a car is probably made up of more than 10000 individual parts that cannot be disassembled, and most of these parts are very small.

What is the measured value of insulation resistance between low-voltage cables and wires, and between wires and ground?

What is the measured value of insulation resistance between low-voltage cables and wires, and between wires and ground?

The standard is not less than 0.5M, but the actual measured data is very uneven. The insulation resistance is directly related to the material, cross-sectional area and length, as well as the number of line connectors and the temperature of insulation recovery! Take the house as an example: in the absence of lighting equipment, it is generally 9~15M, air conditioning socket 30~150, kitchen and toilet 30~200M ordinary socket is the smallest, because the extra power cord needs to be connected, hot tin, to restore insulation, insulation resistance is the smallest, generally not more than 1.5m. This is the insulation resistance of the whole line and the ground two lines. In the case of cable line, the main influencing factors are length, temperature, humidity, construction quality, etc! Usually 100-400 is no problem!

Wire and cable knowledge summary, don't collect it too late!

Generalized wire and cable is also referred to as cable. The narrow sense of the cable refers to the insulated cable. It can be defined as an assembly consisting of one or more insulated cores, and their respective possible cladding, total protective layer and outer sheath. The cable may also have additional uninsulated conductors.

What are the hazards of unqualified wires and cables

What are the hazards of unqualified wires and cables

Wire and cable is a large class of electrical products used to transmit power, transmit information and realize electromagnetic energy conversion. Wire and cable play an important role in all economic activities and social life. It can be said that where there are people living, where there are production, transportation and all economic activities, are inseparable from the wire and cable, so the quality of wire and cable directly affects our lives.

What are the considerations for the selection of wires and cables?

What are the considerations for the selection of wires and cables?

Check the CCC certification mark. Wire and cable products are national mandatory safety certification products. All manufacturers must obtain the CCC certification of the China Electrical Products Certification Committee, and have the CCC certification mark on the certification or product.
