Scope and connection method of MPP power cable protection tubeScope and connection method of MPP power cable protection tube
Application scope of MPP power cable protection tube:
MPP power cable protection tube can be widely used in municipal, telecommunications, electric power, gas, tap water, heat and other pipeline projects.
MPP power cable protection pipe urban and rural non-excavation horizontal directional drilling power drain project, and lighting excavation power drain project.
MPP power cable protection pipe urban and rural trenchless horizontal directional drilling sewage drainage pipe project, industrial wastewater discharge project.
1. During the transportation and construction of MPP power cable protection tube, it is strictly forbidden to throw, hit, scratch, and expose to any place.
2. When the MPP power cable protection tubes are hot-melt butt jointed, the axes of the two tubes should be aligned, and the end face cutting should be vertical and flat.
3. The processing temperature, time, pressure, and weather conditions of MPP power cable protection tube are adjusted accordingly.
4. The minimum bending radius of MPP power cable protection tube should be ≥75 tube outer diameter.

Welding and welding with a welding machine, the welding point is about 220 degrees, according to the temperature change, make appropriate adjustments. When the temperature is low, it can be appropriately increased by 5-10 ℃, and when the temperature is reached, the two ends can be docked. (Because the connection method of the MPP power cable protection tube is hot melt welding, the welding port is not good, it will damage the cable or may be flattened, so the MPP power cable protection tube must be made of new materials)
The MPP power cable protection tube uses modified polypropylene as the main raw material. It does not require a large amount of dredging, earth digging and road surface destruction. It lays pipelines, cables and other construction projects in special sections such as roads, railways, buildings, and riverbeds. Compared with the traditional "digging and burying pipe method", the trenchless power pipe project is more suitable for the current environmental protection requirements, removing the dusty, traffic jam and other disturbances caused by the traditional construction, this technology can also Lay pipelines in areas where excavation work is carried out, such as monument protection areas, downtown areas, crop and farmland protection areas, highways, rivers, etc.
The MPP power cable protection tube has the characteristics of high temperature resistance and external pressure resistance, and it is suitable for high voltage transmission line cable exhaust pipe materials above 10KV. MPP power cable protection tube is divided into ordinary type and reinforced type. The ordinary type is suitable for the excavation and laying construction and the non-excavation crossing construction with a buried depth less than 4M; the enhanced type is suitable for the non-excavation crossing construction with a buried depth greater than 4M. MPP power cable protection tube trenchless tube is also called MPP jacking tube, MPP support tube, MPP traction tube.
