The non excavation modified polypropylene (MPP) protective tube for power cables is a new type of plastic pipeline made mainly of modified polypropylene, using special formulas and processing techniques. It has a series of advantages such as high strength, good stability, easy cable threading and laying, simple construction, and cost savings. As a top pipe construction that highlights the product's personality, it meets the development requirements of modern cities and is suitable for burial depths ranging from 2-18 meters. The modified MPP power cable sheath is constructed using non excavation technology, which ensures the reliability of the pipeline network, reduces the failure rate of the pipeline network, and greatly improves the urban environment.
1. MPP power pipe has strong practicality: MPP power cable pipe has good electrical insulation and is suitable for cable conduit pipes of high-voltage transmission lines above 10KV. The inner wall of the pipe is smooth, with an internationally recognized orange red color that is easy to identify.
2. Strong corrosion resistance: Except for a few strong oxidants, most chemical media cannot corrode, and the acid-base factors of the general use environment will not damage the pipeline.
3. Strong impact resistance: Due to the good toughness of the pipeline substrate, it has high thermal deformation temperature and low-temperature impact performance. When subjected to external impact, it is easy to recover its original shape and will not break even in the case of foundation settlement.
4. Strong aging resistance: In an environment that is not exposed to direct sunlight and ultraviolet rays, the service life of the pipeline can reach more than 50 years.
5. MPP power pipes have good cold resistance: MPP power pipes can be used for a long time at temperatures ranging from -5 to 70 degrees Celsius. Under low temperature conditions (-30 ℃), no special protective measures are required during construction, and the pipes will not freeze or break.
6. Easy construction and low cost: The pipeline is lightweight, easy to transport, has a simple welding process, is easy to construct, can save a lot of engineering time and cost, and has a low overall cost.
7. MPP pipe mechanical performance: overcomes the disadvantage of PE pipe's significant decrease in mechanical performance above 40 ℃ and inability to be used for cable conduit, and overcomes the disadvantage of CPVC pipe's poor resistance to ground settlement.
8. Reliable connection performance: The hot melt joint of the pipe has high strength, and the joint will not break due to soil movement or live load. The wear resistance is even higher than that of the steel pipe, and the friction resistance is small.
