Modified polypropylene (MPP) power cable protection tube is modified polypropylene as raw material, through extrusion forming processing. It can not only use traditional excavation method, but also trenchless pipe-jacking way. Compared with the traditional "excavated buried pipe method", trenchless method is more suitable for the current environmental protection requirements of no dusty and easy transportation. This technology can lay pipe in some areas cannot be implemented excavation work (such as urban, cultural relics protection, crops protected areas, highways, rivers etc.). MPP pipes diameter is 110-250mm, normal and reinforced two types. Normal one is suit for the excavation and trenchless across bury construction less than 4 meters. The reinforced type is suit for trenchless across bury construction more than 4 meters .
