The application of electric wire and cable can be summarized into three major application areas du.
1, power system zhidao
Wire and cable products used in power systems mainly include bare wires for overhead transmission lines, bus bars (bus bars), power cables, and wires and cables for electrical equipment for electrical equipment.
2, information transmission system
Wires and cables used in information transmission systems include telephone cables, cable television cables, data transmission cables, radio frequency cables for mobile wireless communication systems, and various electronic cables. In recent years, the proportion of fiber optic cables in information transmission networks has increased rapidly and has become the main transmission medium for information transmission lines.
3, electrical equipment, electrical appliances, internal wires and cables
In the two major systems of power and information, from the starting point of the system (such as generators and signal transmitters), through various nodes of the system (such as transformers, program-controlled switches) to user terminals (such as household appliances, telephones, televisions, and computers), All these equipment use a lot of wires and cables.
According to their functions, these wires and cables are divided into: one type is the carrier electromagnetic wire (winding wire) that converts electrical energy into magnetic energy or magnetic energy into electrical energy; the other type, as the connecting wire of the components in the device, plays the role of transmitting electrical energy or The role of transmission signals.
