The wire function is mainly to transmit electrical energy, signals and electromagnetic conversion. The transmission of electricity is such as power cables, overhead cables, etc. The transmission signal has coaxial cables to achieve electromagnetic conversion such as lacquer cables.The occurrence, transmission, and application of electromagnetic waves must be used as a wires that are connected, transmitted, or as the winding materials of the host.So what parts are composed of wires? What are the choice standards?
Wire composition
The conductor is the conductive part of the wire and cable. It is used to transport the power and is the main part of the wire and cable.
Insulation
The insulation layer is an indispensable part of the electrical energy transport between the conductor with the earth and the conductivity of the earth and the different phase of the conductor, which is an indispensable part of the wire and cable structure.
Shield
15KV and above wire and cables generally have conductive shielding layers and insulating shields.
The protective layer
The role of the protective layer is to protect the invasion of external impurities and moisture, and prevent external forces from directly damaging the power cable.
Selection criteria
1. Select copper core wires: Cable wires, first of all, the conductive performance must be good.There are copper -core wires and other wires on the market.Copper core wires are the most practical interior decoration.However, there are several types of copper core wires, with large radius copper cores and multi -line copper cores.
2. Rods with strong load capacity: The electricity consumption in the family is large and small. At the largest, we will drive TV, air conditioner, computer, turn on light, turn on water dispenser, refrigerator, hair dryer, etc.If the load capacity of the wire is not strong, and the hot summer, it will easily cause the wires to burn due to high temperature and cause the fire.
3, good waterproof performance.Some wires are easy to deformed the cracks. In case of leakage, the electrical appliances will be burned, and short circuits will even cause fire and casualties.Therefore, we must have a hard skin and good waterproof performance.
4. The main line must be a rough core.The so -called main line refers to the two leading lines from the total power supply to all electrical appliances.The main thread must use a thick copper core, because the main line is loaded with the charge of each electrical appliance, and the thick copper wire with excellent performance is required.You can choose multi -core wires by bypass.
