Description

Technical Field

[0002] Power pipelines are products coated with hot-dip plastic by PE (modified polyethylene) or coated inside and outside with epoxy resin, which have excellent corrosion resistance; at the same time, the coating itself also has good electrical insulation and will not cause electrolytic corrosion. Power pipes are usually used as cable protection pipes. This product has the characteristics of high strength, good flexibility, high temperature resistance, corrosion resistance, flame retardancy, good insulation performance, pollution-free, not easy to age, light weight, and convenient construction. Its various performance indicators have reached or exceeded the domestic similar product level through national, provincial inspections, appraisals and certifications. The product performance is much better than traditional asbestos cable pipes and ordinary PVC pipes, and it is an ideal substitute for traditional power cable protection pipes. Power pipes are widely used in urban power grid construction and renovation; urban municipal renovation projects; civil aviation airport engineering construction; engineering park and community engineering construction; traffic and road bridge engineering construction for urban street lamp cable laying, and play a guiding and protecting role.
