PE carbon spiral pipe is a new type of power cable protection pipe produced by extrusion molding and unique rotary molding technology with high-density polyethylene and modified carbon as the main raw materials. Carbon pipe has many advantages such as high strength, high toughness, corrosion resistance, high temperature resistance, high insulation resistance, good flame retardancy, light weight, long service life and not easy to deformation. The carbon bellows has been widely used in urban street lamp line buried engineering, electrified railway power and communication cable laying buried Engineering, highway power and communication facilities construction and transformation engineering, Residential area construction project and buried cable project in parks and large entertainment places are the most ideal buried cable sheath pipes at present.
