1. High strength, light weight, generally 1/6 of steel pipe and 1/10 of cement pipe. It is easy to transport and install without special equipment.
2. Good flexibility, not easy to break, good seismic resistance and resistance to uneven settlement, greatly superior to the traditional cement pipe and asbestos pipe.
3. Convenient construction: the socket connection is adopted, and the combined support and other accessories are convenient for pipe laying construction and installation, which can greatly shorten the construction period, and do not need to cast concrete protective layer. The overall project cost is low, and has significant economic benefits;
4. The core temperature of high voltage power cable with excellent heat resistance during normal operation varies with the voltage. For example, when the temperature of the cable core conveying 110kva voltage is transmitted to the bushing, the normal temperature is 65 ℃, and the overload temperature is 75 ℃. PV-C material has a thermal deformation temperature of more than 93 ℃, which can adapt to the high temperature environment, and it can work normally without deformation.
5. Excellent electrical performance: flame-retardant, flame-retardant, volume resistivity ≥ 1.0 × 1011 ☊. m, with good insulation performance and safe use.
