RVV power cord is a common wire and cable in weak current system. Two or more RV wires are added with a sheath. The core of the internal chaos is not only 2 cores, but also has 3 cores, 4 cores, 6 cores and other power cords.

The copper core conductor of the RVV power cord has the same outer layer as the RVS copper core conductor, and the outermost layer also has a sheath, which belongs to the environmental protection cable. The copper core wire in the RVV power supply line is generally not twisted in parallel.

 

The RVS wire is a twisted pair cable, that is, two plastic copper soft RV wires are twisted together in a twisted manner, and are used for public broadcasting system wiring and fire protection systems on weekdays.

At the time of wiring, there are not many straight lines in the loop, no wires, and RVS wires can be selected without wall penetration. The RVV power cable can be selected for the trunk and multi-loop number wiring.
