With the rapid development of the country's economic development, urban construction is increasingly updated, and power cables have entered the ground from overhead. In order to meet the needs of the market, the company introduced new foreign technology and new technology, and developed a new type of buried high-voltage power cable protection tube made of CPVC as the master batch, and added auxiliary materials such as impact stabilizer and stabilizer through high-speed extrusion. This product is a new type of electric power pipe with high strength, corrosion resistance, no pollution, light weight, and convenient construction and installation. It is mainly used for power cable laying and plays a guiding and protecting role. The product is flared and socketed, and the joint is sealed with a high temperature resistant rubber ring to prevent the effects of thermal expansion and contraction. It replaces the traditional UPVC double-wall corrugated pipe with poor ring stiffness, heat resistance of PE plastic pipe, flame retardancy, and poor ring stiffness. It is based on PVCC and is a modern new product.
Buried high-voltage power cable protection pipes are made of CPVC resin with excellent heat resistance and excellent insulation properties. CPVC products are currently recognized as green products, and their excellent physical and chemical properties are receiving increasing attention from the industry.
CPVC buried high-voltage power cable protection tube is a rigid straight solid wall tube. The inner and outer walls are smooth and flat, the color is orange-red, and the color is bright and eye-catching.
The CPVC buried high-voltage power cable protection pipe has a 15 ° C higher heat resistance than ordinary UPVC double-wall corrugated pipes. It can remain undistorted in an environment above 93 ° C and has sufficient strength.
3. Insulation performance
CPVC buried high-voltage power cable protection tubes can withstand high voltages of more than 30,000 volts. In the current urban power grid transformation, high-voltage power cables are generally less than 10,000 volts, so for urban power grids, the electrical insulation performance of the protection tube has been Greater than the electrical insulation performance of power cables, it will be safer to use.
4. Compression resistance
CPVC buried high-voltage power cable protection pipe has been modified by materials, and the ring stiffness of the product has reached 10Kpa, which is significantly higher than the relevant national authorities' requirements for the rigidity index of buried plastic pipe rings. National standards require buried plastic that crosses motor vehicle roads. The ring stiffness of the pipe should be above 8Kpa. It can be seen that the buried pipe has excellent buried pressure resistance and is completely suitable for various road constructions.
5. High impact strength
The buried high-voltage power cable protection tube can withstand a 1Kg weight and an impact force of 2m height, which fully reflects the low-temperature impact performance of the material, which is fully applicable to the requirements of the construction environment.
6. Flame retardant performance
Both PVC and CPVC materials have good flame retardancy and can be extinguished immediately after fire. Especially CPVC material, because it has one more chlorine atom than PVC, so the flame retardancy and smoke density index are significantly improved.
7. Installation performance
The buried high-voltage power cable protection tube is light in weight, high in strength, and simple in construction and laying methods. It can be excavated and buried at night, backfilled the road, and can be opened to traffic as usual during the day. The elastic sealing rubber ring is used for plug-in connection, and the installation and connection are convenient, fast, The connection has good sealing performance, can prevent groundwater leakage, and effectively protect the safety of power cables.
8. Long life
CPVC material is resistant to corrosion and aging and has a service life of more than 50 years.
9. High cost performance
Compared with cement pipe, asbestos pipe, glass steel pipe, it is energy-saving and pollution-free. The price is slightly lower than similar cement pipes, 20% lower than similar steel pipes, and the overall cost can be reduced by 15%.
The main performance indicators of buried high-voltage power cable protection pipes produced by Fuyang Bainuo Pipeline Co., Ltd. are as follows, and passed the test of National Chemical Building Material Quality Supervision and Testing Center, Power Industry Power Equipment and Line Equipment Quality Inspection and Testing Center.
