PVC power pipes have high mechanical strength at high temperature and are suitable for pressure applications. The service temperature is up to about 90 ℃, and the service life can reach 50 years. It is safe and simple. The connection methods are flux bonding, threaded connection, flange connection and welding rod connection. Flame retardant, fireproof, low thermal conductivity, less pipeline heat loss, low installation cost, but pay attention to the toxicity of the glue used. PVC-C resin is a new type of buried high-voltage power cable protection pipe, which is made of masterbatch, anti impact agent, stabilizer and other auxiliary materials by high-speed extrusion.

This product has the characteristics of high strength, good flexibility, high temperature resistance, corrosion resistance, flame retardancy, good insulation, no pollution, not easy to aging, light weight, convenient construction, etc. Its various performance indicators have been tested, identified and certified at the national and provincial levels, and have reached or exceeded the domestic level of similar products. The product performance is much better than the traditional asbestos cable duct and ordinary PVC pipe, and it is an ideal substitute for the traditional power cable sheath.
