The PE protective casing for power cables is a high-tech product primarily made from high-density polyethylene resin, with appropriate additives mixed in and processed through extrusion. This product features corrosion resistance, aging resistance, impact resistance, high mechanical strength, long service life, and excellent electrical insulation properties, making it widely applicable in fields such as underground high-voltage cables and streetlight cable protective casings. Advantages of PE power cable protective pipes: Excellent physical properties: Produced using polyethylene materials, it possesses good rigidity and strength, as well as excellent flexibility, facilitating the installation of pipelines. Corrosion resistance and long service life: In coastal areas where the underground water level is high and soil humidity is significant, using metal or other types of pipes requires corrosion protection, with an average lifespan of only 30 years. In contrast, PE pipes can withstand various chemical media and are not affected by soil corrosion. Good toughness and flexibility: PE power pipes are made of highly flexible materials with a break elongation rate exceeding 500%. They have strong adaptability to uneven ground settlement and displacement. They also exhibit good seismic resistance, and small diameter pipes can be bent freely. Smooth pipe walls with low friction coefficients facilitate easy cable threading and high construction efficiency. Good electrical insulation properties and long service life (buried pipes can last over fifty years), ensuring durability and reliability in line operations. Lightweight PE protective tubes are easy to maintain, install, and transport, making them convenient to handle. Small diameter pipes can be made in coil form, with long pipe sections and fewer joints, simplifying installation. Pipes can be produced in various colors for differentiation. Excellent low-temperature impact resistance: The low-temperature embrittlement temperature of PE is very low, allowing safe use within a temperature range of -20 to 40 degrees. During winter construction, the material's good impact resistance prevents pipe brittleness. Good wear resistance: Compared to other metal pipes, PE pipes have four times the wear resistance of metal. Various innovative construction methods for power protective pipes: In addition to traditional excavation methods, PE pipes can also be installed using various innovative trenchless technologies, such as pipe jacking, relining, and bursting methods, making them suitable for locations where excavation is not permitted.
