Electricity PVC pipe Description: [* Material properties: buried high-voltage power cable protection tube with excellent heat insulation performance of CPVC resin as the main material, is widely recognized as a green product, inner and outer walls smooth, color was orange color bright and eye-catching. * Heat resistance: CPVC underground high-voltage power cable protection tube than ordinary UPVC double-wall corrugated pipe heat temperature increased 15 ℃, can be at least 93 ℃ environment, maintaining deformation, and has sufficient strength. * Insulation: CPVC underground high-voltage power cable protection tube can withstand 30,000 volts or more high pressure, in the current urban power grids, high-voltage power cable Generally million volts or less, so for the purposes of urban power grids, the protective tube electrical insulation properties is greater than the electrical power cable insulation, safer to use. * Compression performance: CPVC underground high-voltage power cable protection tube through material modification, product ring stiffness reach 10Kpa, significantly higher than the national authorities for buried plastic pipe ring stiffness index requirements, national standards for motor vehicles crossing plastic pipe buried roads, the ring stiffness should 8Kpa more. Visible, buried in the protective tube compression performance is very good, fully applicable to the construction of various roads. * Installation Performance: Light buried high-voltage power cable protection tube weight, high strength, laying the construction method is simple, can achieve at night laying excavation, backfill the road open to traffic during the day as usual; elastic rubber ring seal socket connection, installation and connection convenient, fast, good sealing performance connection, can prevent groundwater seepage, effective protection of safe power cable. * Long life: CPVC materials resistant to corrosion, aging, life of up to 50 years. * The physical properties of chlorinated PVC pipe project units hard PVC cable conduit cable conduit density 3 ≤1.6 ≤1.55 ring stiffness (3%) at room temperature 80 ℃ kPa compliance with DL / T802.3-2007 Table 1 Subject DL / T802.3-2007 flattening test specified in Table 1 to the vertical loading deformation of the inner diameter of the sample was 30% of the original sample should not crack or rupture drop hammer impact test specimens does not crack or break Vicat softening temperature ℃ ≥93 ≥80% ≤5 longitudinal reversion
