Wuhan power grid reconstruction started in many places MPP power pipe application demand rose

MPP power pipe is a special pipe for power cable protection made of modified polypropylene as the main raw material. Its main function is to isolate external environmental influences during the laying of power cables and reduce the risks caused by external damage and environmental corrosion to cable operation. Recently, many urban areas in Wuhan have launched renovation projects such as old power grid upgrades, distribution network expansion, and offline power pipes. Due to the wide coverage of the project and the complex construction scenarios, the demand for suitable power protection pipes has increased significantly. MPP power pipes have become one of the most widely used pipe categories in this renovation project due to their performance characteristics suitable for distribution network engineering requirements.

The core practical selling points of this product mainly include four points: First, corrosion resistance and aging resistance are stable. The pipe can withstand the long-term erosion of ordinary acid and alkali soil and humid environment. The service life in the buried use scenario meets the long-term operation and maintenance requirements of power engineering. There is no need to replace the pipe frequently, which can effectively reduce the subsequent operation and maintenance cost of the power grid. Second, the insulation flame retardant performance conforms to the power safety specifications. The product itself has qualified insulation performance, which can isolate the influence of external water vapor and metal impurities on the cable, reduce the risk of leakage, and at the same time have flame retardant characteristics. It is not easy to spread the flame damage when encountering external open flames, which can reduce the hidden dangers of power safety. Third, the construction is convenient to adapt to The weight of MPP power pipe is much lower than that of metal pipes of the same specification. It can be connected by hot melt, and the interface sealing performance is good. At the same time, it is suitable for non-excavation pipe jacking construction technology. In construction scenarios such as the old city of Wuhan, which are not suitable for large-scale road breaking, it can reduce the impact on residents' travel and the operation of merchants along the street, and shorten the overall construction period. Fourth, the anti-deformation ability is suitable for complex geology. The pipe has good anti-stamping and anti-settlement properties. It can withstand external extrusion caused by vehicle load and soil settlement, and is not prone to deformation and fracture problems. It can provide continuous and stable protection for internal cables.

At present, the pipe is mainly suitable for the upgrading of the power grid in old residential areas, the launching of municipal road power pipelines, the construction of power supporting facilities in industrial parks, and the renovation of power pipelines along rail transit lines in Wuhan Power Grid Reconstruction Project. It is suitable for use by power grid engineering contractors, municipal engineering construction parties, power grid operation and maintenance management departments, power pipeline design units, and other relevant entities. Products of corresponding specifications can be selected according to the pipe diameter and pressure level requirements of different projects.

At present, the production, testing and application of MPP power pipes strictly follow the relevant material standards and construction specifications of national power engineering. All products used in the field need to be tested in multiple dimensions such as appearance, strength, and insulation performance. After the inspection meets the standards, they can be put into engineering use. It can stably adapt to the diverse construction needs of Wuhan's power grid transformation, and provide reliable pipeline protection support for the safe advancement and high-quality delivery of the power grid transformation project.
