[0002] MPP pipe fittings are a type of pipe fittings used to protect power cables. They are made of modified polypropylene material and have electrical insulation, high temperature resistance and corrosion resistance. They are widely used in power cable laying projects in urban power grids, industrial parks, residential areas, etc. They can effectively protect cables from the influence of the external environment and improve the safety and reliability of the power system.
[0003] Most existing MPP pipe fittings may gradually rust after long-term service, even if the material itself has good performance. Especially in harsh environments, long-term operation may cause the strength of the pipe fittings to decrease, and they may easily break when subjected to external forces, shortening their service life.
[0004] In addition, most existing MPP pipe fittings use threads to connect pipes, which cannot tighten the gap between the fittings and the pipes, which may lead to poor sealing effects and fail to effectively prevent liquids or gases from penetrating from the connection parts, which may cause the cable to get damp.
[0005] Therefore, those skilled in the art provide a new anti-corrosion pipe fitting to solve the problems raised in the above background technology. Utility Model Content
