With the development of the economy and the large consumption of energy, the demand for cables will increase. At the same time, power cables are widely used in buildings because of their good durability, such as power cables and thermal power generation. cables, industrial cables and data transmission cables. Then you need to choose a cable with good quality and can guarantee its good quality. Let's talk about the performance characteristics of low-voltage insulated power cables.
The high temperature cable is a wire and cable with multiple strands of soft copper as the conductor. The selection of heat-resistant and high-temperature wires and cables is determined by the needs of the two uses. One is that the working temperature of the wire and cable is relatively high, and the cable can normally transmit signals or electric energy for a long time in high temperature weather; the other is the power engineering transmission cable, which is usually used to improve the professional ability of the interceptor.
PVC cable is based on polyvinyl chloride resin, adding stabilizers and other materials mixed and extruded into insulation materials required for wire and cable. The wires and cables made of polyvinyl chloride cables are called polyvinyl chloride wires and cables, which have good flame retardancy, and the gas released in case of fire will not cause serious secondary damage to the human body.
The number of cores and production usage scenarios of overhead cables are different, and the specification parameters are also different. We need to choose cable models with different cores according to different specifications.
