1. Light weight, easy to transport and transport, low labor intensity, 1/6 of the steel pipe
2. It is resistant to corrosion, aging, rust and has a long service life. PVC-C pipes are resistant to acid, alkali, salt, oil, electricity and other media, with a wide geological adaptation range;
3. Good electrical resistance, flame retardancy, self extinguishing, durable, reliable line operation. The volume resistivity is high, and the performance of the isolating electrode is excellent, which can withstand high voltage above 30000 volts;
4. High strength, heat resistance and long service life. The Vicat temperature of PVC-C power cable casing reaches above 93 ℃
PVC is 10 degrees higher. Compared with the traditional asbestos cement pipe, it has good flexibility, high temperature resistance, is not easy to break and age, and has a long service life
Long life, no radioactive pollution and other advantages. Its strength can replace the steel pipe to avoid damage caused by high temperature of single core cable caused by closed magnetic circuit formed by the steel pipe.
5. Convenient construction. The conduit is composed of joints, waterproof sealing rings, brackets and other components. The design is reasonable and the construction is convenient. Generally, the concrete protective layer does not need to be poured.
6. It has superior cost performance and obvious economic and environmental benefits.
