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
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.
During the laying and installation process, the insulation resistance of the cable should be measured frequently, and problems should be dealt with in time.
