Henan Energy Electric Equipment Co., Ltd. was established in 2011 and is an excellent and reliable power equipment manufacturer in China. The company mainly develops and produces oil-immersed transformers, dry-type transformers, box-type substations, high-voltage switches, and medium and low voltage complete sets of equipment. The equipment put into production and operation of the project advocates energy saving, intelligence, informatization, and mechanization. The company has established the Henan Triangle Energy-saving Transformer Engineering Technology Research Center, with 71 utility model patents and 15 invention patents. With years of accumulation in the transformer industry and strong technological innovation capabilities, HZEC products are sold to the Middle East, North America, South America, Europe, Southeast Asia, Africa, and other regions, covering more than 40 countries.
Product Description
Chlorinated polyvinyl chloride (PVC-C) plastic cable conduit is referred to as PVC-C power conduit or CPVC power conduit. It is made of chlorinated polyvinyl chloride (PVC-C) resin as the main material, with necessary processing aids added, and is formed after extrusion. It is an improved power sheath pipe with excellent heat resistance. It is suitable for the laying of power cables and plays a guiding and protective role. Its excellent physical and chemical properties are increasingly valued by the power and communication industries and are widely used. The use of high heat-resistant CPVC power cable protection pipes for the laying of power cable conduits is an inevitable trend in the future development of the power industry.

Main Features
1. High strength and light weight, generally 1/6 of steel pipes and 1/10 of cement pipes, easy to transport and install, no special equipment required;
2. Good flexibility, not easy to break, good earthquake resistance and resistance to uneven settlement, greatly superior to traditional cement pipes and asbestos pipes;
3. Convenient construction: Socket-type connection, combined with accessories such as modular brackets, is convenient for pipe construction and installation, which is convenient and fast, can greatly shorten the construction period, and does not require pouring concrete protective layer, the overall project cost is low, and has significant economic benefits;
4. Excellent heat resistance: The cable core temperature generated by high-voltage power cables during normal operation varies with the voltage. For example, when the temperature of the cable core of a cable with a voltage of 110KVA is transmitted to the casing, it is 65ºC under normal circumstances and can reach 75ºC under overload. The PVC-C material has a heat deformation temperature of more than 93ºC, which can adapt to high temperature environments and remain unchanged during normal operation;
5. Excellent electrical properties: flame retardant, extinguished immediately after leaving the fire, volume resistivity ≥1.0×1011Ω.m, good insulation, safe to use;
6. Corrosion-resistant, wear-resistant, aging-resistant, crack-resistant, long service life, up to more than 50 years;
7. Compared with cement pipes, asbestos pipes, and fiberglass, it is environmentally friendly, energy-saving, and pollution-free;
8. Superior performance-price ratio: PVC-C pipes are slightly lower than similar cement pipes and 20% lower than similar steel pipes, and the comprehensive cost can be reduced by 15%.
