A centre conductor which is usually a copper wire, which data and video travels through2. A braided mesh made from copper then helps to shield the cable from electromagnetic interference (EMI)4.

Coaxial cable has a distinct thick, round shape because of its interior insulation layer. Its size makes it look very different to other types of cable

Know the voltage level. Know the types of poles and towers. If you have these characteristics, you can determine that the line voltage of the wire is 380 volts, and the phase voltage is 220 volts.

During home decoration, the equipment engineering cables should be installed properly, and the regulations should be strictly implemented to plan and design the route as a whole.

1. Before laying the cable, check whether the cable model meets the design requirements, whether the cable appearance is damaged, and whether the insulation resistance meets the standard requirements, etc.;
2. Understand the structure, performance and characteristics of fire-resistant cables,

As a wire and cable supplier, the following The method can reasonably reduce the occurrence rate of wire and cable skin falling.1.
