Cable protection pipes are also called cable pipes, power cable pipes, cement cable pipes, power drainage pipes and power cable protection pipes. Cable protection tube is mainly installed at the intersection of communication cable and power line to prevent short circuit accident caused by power line disconnection, so that communication cable and wire rope are electrified, thus protecting cable, switch, moving plate and even the whole machine from being burned out, and also playing a certain role in isolating magnetic field interference of power line.

With the development of the times, composite materials made of cement or other nonmetals are gradually replaced by FRP. Most cable protection pipes made of FRP can improve their corrosion resistance and service life underground, with smooth surface and outstanding cleaning performance.
