This is a kind of synthetic resin with high temperature and high-pressure resistance, which plays a very important role in various situations in our life, such as high temperature and high intensity working environment. No matter in power sector or communication sector, people are using MPP electricity pipes to protect cables. In general, MPP electricity pipes are divided into two types: one is ordinary MPP electricity pipes, and the other is enhanced MPP electricity pipes. The ordinary MPP electricity pipes are mainly used in common cable construction and trenchless perforation construction work, and the vertical distance from the ground is generally less than 4 meters. Enhanced MPP electricity pipes are mainly used in construction above 4 meters above the ground.
