| 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, light weight, generally 1/6 of steel pipe, 1/10 of cement pipe. Transportation and installation are portable without special equipment: 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, not easy to break, good seismic resistance and non-uniform settlement resistance, which is much 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: It is easy to arrange pipes and install with socket connection, combined support and other fittings. It is convenient and fast. It can greatly shorten the construction period, and does not need to pour concrete protective layer. The overall project cost is low. It has remarkable 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； 4. Excellent heat resistance: The core temperature of high-voltage power cables in normal operation varies with the voltage. For example, when the temperature of the cable core conveying 110KVA voltage is transferred to the casing, it can reach 65 C under normal conditions, 75 C under overload conditions, and the thermal deformation temperature of PVC-C material is above 93 C, which can adapt to the high temperature environment and keep the normal operation unchanged. 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, extinguishing immediately after fire, volume resistivity (> 1.0 *1011_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 50 years or more: 7、与水泥管，石棉管，玻璃钢比较，环保节能，无污染； 7. Comparing with cement pipe, asbestos pipe and FRP pipe, it is environmentally friendly, energy-saving and pollution-free. 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. Performance-price ratio is superior: PVC-C pipe is slightly lower than the same kind of cement pipe, 20% lower than the same kind of pipe, and the comprehensive cost can be reduced by 15%. |
