| PVC-C电力管特性 Characteristics of PVC-C power pipe 1、强度高，重量轻，一般为钢管的1/6，水泥管的1/10。运输与安装轻便，无需专用设备： 1. High strength and light weight, generally 1 / 6 of steel pipe and 1 / 10 of cement pipe. Light transportation and installation, no special equipment required: 2、柔性好，不易断裂，抗震性及抗不均匀沉降性好，大大优越于传统的水泥管和石棉管： 2. It has good flexibility, is not easy to break, has good seismic resistance and differential settlement resistance, and is greatly superior to the traditional cement pipe and asbestos pipe 3、施工便捷：采用承插式连接，配合组合式支架等配件便于排管施工和安装，方便快捷，可大大缩短施工周期，并且不需浇注混凝土保护层，整体工程造价低，具有显著的经济效益： 3. Convenient construction: the use of socket connection, combined support and other accessories is convenient for pipe laying construction and installation, convenient and fast, can greatly shorten the construction period, and does not need to cast concrete cover, the overall project cost is low, with significant economic benefits: 4、优良的耐热性：高压电力电缆在正常工作时产生的缆芯温度随电压的高低而不同。如输送110KVA电 4. Excellent heat resistance: the core temperature of high-voltage power cable in normal operation varies with the voltage. Such as 110KVA power transmission 压的电缆缆芯温度传送至套管时，正常情况下位65℃，过载情况下可达75℃，PVC-C材料具有93℃以上的热变形温度，可适应高温环境，正常工作保持不变形； When the temperature of the pressed cable core is transmitted to the sleeve, it is 65 ℃ under normal conditions, and 75 ℃ under overload conditions. PVC-C material has a thermal deformation temperature of over 93 ℃, which can adapt to high temperature environment and maintain no deformation during normal operation; 5、电气性能优良：阻燃，离火即熄，体积电阻率≥1.0×1011Ωm，绝缘性好，使用安全： 5. Excellent electrical performance: flame retardant, flameout when off fire, volume resistivity ≥ 1.0 × 1011 Ω m, good insulation, safe use: 6、耐腐蚀、抗磨损、耐老化、抗开裂，使用寿命长，可达50年以上： 6. Corrosion resistance, wear resistance, aging resistance, cracking resistance, long service life, up to more than 50 years: 7、与水泥管，石棉管，玻璃钢比较，环保节能，无污染； 7. Compared with cement pipe, asbestos pipe and glass fiber reinforced plastic, it is environmentally friendly and energy-saving without pollution; 8、性能价格比优越：PVC—C管材比同类水泥管略低，比同类钢管低20％，综合造价可降低15％。 8. Superior performance price ratio: PVC-C pipe is slightly lower than similar cement pipe, 20% lower than similar steel pipe, and the comprehensive cost can be reduced by 15%. |
