CPVC Eelectric pipe is a new type of buried pipe designed specifically for the protection of high and low voltage power cables. It is made of high-quality chlorinated polyvinyl chloride resin as the core material and refined through high-temperature modification and extrusion molding processes. It is an upgraded substitute for traditional steel pipes and cement pipes and is widely used for underground cable laying protection in power engineering.
The product adopts a single pipe structure, with uniform wall thickness and dense texture. The core design revolves around the dual requirements of "electrical protection+physical protection": on the one hand, relying on the excellent insulation performance of CPVC substrate itself, after modification treatment, it strengthens the breakdown resistance, effectively isolates high-voltage electric fields, and eliminates the risk of leakage; On the other hand, by optimizing the formula, the rigidity and toughness of the pipe body are improved, taking into account the characteristics of resistance to heavy pressure, impact, and corrosion, providing comprehensive protection for power cables.
Its core advantages are focused on "safety protection+strong adaptability": outstanding temperature resistance, long-term use temperature can reach 93 ℃, able to resist cable short circuit high temperature; Acid and alkali resistance, salt fog resistance, anti-aging, suitable for a variety of complex soil and outdoor environment; The connection method is flexible (socket, rubber ring sealing, hot melt docking), the construction is convenient and the sealing is tight, which can meet the needs of power pipeline construction in multiple scenarios such as municipal, power grid, transportation, and industrial and mining. It is the preferred protective pipe for buried laying of power cables.
