As wire and cable products are closely related to the lives of consumers, the quality and safety of wire and cable directly affect the personal safety and property safety of consumers, so how to correctly install and use wire and cable is particularly important.

Wire and cable is closely related to people's production and life, its safe operation is not only related to the normal operation of the power system, but also related to the safety of people's lives and property. The cable will heat up when it passes through a certain load current. With the increase of load current, the cable surface temperature will be higher. If it is not handled in time, it may cause fire accidents and threaten life safety.

Wire and cable are mainly composed of conductive wire core, insulation layer and sheath layer three basic structural components.

Shielding wire is a transmission line that uses a metal mesh braid layer to wrap the signal line, and the braid layer is generally red copper or tinned copper. The shielding layer of the shielding line needs to be grounded, and the external interference signal can be imported into the earth by this layer.

The vast majority of people in daily life do not know much about wire and cable such products, it is easy to confuse together, in fact, there is a big difference between the two.

Cable is used to transmit electrical (magnetic) energy, information and electrical (magnetic) energy conversion of wire products, it is a wide variety, according to the use of division, there are bare copper wire, power cables, control cables, overhead cables, communication cables, special cables and so on. Different cables are suitable for different industries and working conditions, but looking at these various categories, may everyone be cross-eyed, do not know what they should use? The follo
