1. Product introduction of power cable protection casing excavation type and non-excavation type. MPP non-excavation type power pipe is also known as MPP jacking pipe or support pipe. MPP power pipe adopts modified polypropylene as the main raw material. It is a construction project for laying pipelines, cables, etc. in special areas such as roads, railways, buildings, and under riverbeds without the need for extensive dredging, excavation and damage to the pavement. Compared with the traditional “trenching and burying pipe method”, unexcavated power pipe projects are more adapted to current environmental protection requirements and remove disturbing factors such as dust and traffic jams caused by traditional construction. This technology can also lay pipelines in areas where excavation operations cannot be carried out, such as monuments reserves, urban areas, crop and farmland reserves, highways, rivers, etc. It has the characteristics of high temperature resistance and external pressure resistance. It is suitable for high voltage transmission lines and pipes above 10KV. 110mm~250mm, divided into normal type and reinforced type. The normal type is suitable for excavation paving facilities and projects where the burial depth of non-excavation crossing construction is less than 4M; the enhanced type is suitable for projects with a burial depth of more than 4M for non-excavation crossing construction. This product has achieved good social and economic benefits through testing by the Chemical Building Materials Testing Center. 2. Scope of application of power cable protective casing MPP power pipes can be widely used in municipal, telecommunications, electricity, gas, tap water, heat and other pipeline projects. 3. The superiority of power cable protective bushing1. MPP power pipes have excellent electrical insulation. 2. MPP power tubes have high thermal deformation temperature and low temperature impact performance. 3. MPP power pipes have higher tensile and compression resistance than HDPE. 4. MPP power pipe is light, smooth, low friction, and can be welded and docked by hot melt welding. 5. The long-term use temperature of MPP power pipes is 5~70℃. 6. Instructions for MPP pipe construction ☆ Arbitrary throwing, impact marking, and exposure to the sun are strictly prohibited during the transportation and construction of MPP power pipes and pipes. ☆ When the MP power pipe is hot-melt butted, the axes of the two pipes should be aligned, and the end face cutting should be vertically flat. ☆ MPP power pipe processing temperature, time, pressure, and climate conditions are adjusted accordingly.
