玻璃钢电力管的功能特性 Functional characteristics of fiberglass electric tube 玻璃钢电力管强度高。用在行车道下直埋无需加混疑土保护层能加快电缆工程建设进度。 FRP high power tube strength. It is possible to speed up the construction of cable projects with the need to bury the dirt in the driveway. 玻璃钢电力管管材有柔韧性。能抵御外界重压和基础沉降所引起的破坏。 FRP power tube steel tubes have flexibility. Can withstand external pressure and the damage caused by foundation settlement. 玻璃钢电力管绝缘、无电腐蚀。适用于单芯电缆敷设;有耐腐蚀的优点，可在高温盐碱地带使用。 FRP electricity pipe insulation, corrosion without electricity. Suitable for single cable installation; Corrosion resistant advantage can be used in high temperature saline zone. 玻璃钢电力管阻燃耐热性能好。可在130度高温长期使用而不变形，同时玻璃钢电力管内壁光滑不刮伤，电缆接头处加橡胶密封适应热胀冷缩有可防止砂泥进入。 FRP electricity pipe flame retardant heat resistant performance is good. At 130 degrees high temperature deformation, use for a long time without FRP power tube inner surface smooth not scratch at the same time, the cable and rubber seal joint to adapt to the heat bilges cold shrink can prevent the sand into the mud.
