The 10kV~110kV composite pillar insulators for power stations are used for power equipment and devices operating in 10kV~110kV AC systems, especially in polluted areas. It can effectively prevent pollution flashover accidents and reduce maintenance workload during operation. It is a new generation of insulator products with excellent performance. 1. Superior electrical performance and high mechanical strength. The tensile and flexural strength of the epoxy glass fiber pull-out rod carried inside is 2 times higher than that of ordinary steel, and 8-10 times that of high-strength porcelain materials, which effectively improves the reliability of safe operation. 2. It has good pollution resistance and strong pollution flashover resistance. Its wet withstand voltage and pollution voltage are 2-2.5 times that of porcelain insulators with the same creepage distance, and no cleaning is required, so it can operate safely in heavily polluted areas. 3. Small size, light weight (only 1/6-1/19 of the same voltage level porcelain insulator), light structure, easy to transport and install. 4. The silicone rubber shed has good water-repellent performance, and its overall structure ensures that the inner insulation is damp, and there is no need for preventive insulation monitoring tests or cleaning, which reduces the workload of daily maintenance. 5. It has good sealing performance and strong resistance to electric corrosion. The shed material is resistant to electric leakage and tracking up to TMA4.5 level. It has good aging resistance, corrosion resistance and low temperature resistance. It can be used in the area of -40℃~+50℃. 6. It has strong impact resistance and shock resistance, good brittleness and creep resistance, not easy to break, bending resistance, high torsional strength, can withstand internal strong pressure, strong explosion-proof force, and can be interchanged with porcelain and glass insulators use.
