Silicone composite insulator series products, whose mechanical properties and electrical properties are better than those of porcelain insulators, have strong operational safety, and are newer products for power lines.

1. Superior electrical performance and high mechanical strength. The tensile and flexural strength of the epoxy glass pull-out rod carried inside is 2 times higher than that of ordinary steel, and 8 to 10 times that of high-strength porcelain materials, which effectively improves the reliability of safe operation.

2. Good anti-pollution performance, good anti-pollution performance, strong anti-pollution flashover, its wet withstand voltage and withstand voltage are 2~2.5 times of the same creepage distance of porcelain insulators. And it does not need to be cleaned, and it can operate safely in heavily polluted places. Small size, light weight (only 1/6~1/9 of the same voltage level porcelain insulator), light structure, easy to transport and install.

3. The silicone rubber shed has good water-repellent performance. Its overall structure ensures that the inner insulation is not damp, and there is no need for preventive insulation monitoring tests and cleaning, which reduces the daily maintenance workload.

4. Good sealing performance, strong resistance to electrical corrosion, the shed material is resistant to electric leakage and tracking up to TMA4.5 level, has good aging resistance, corrosion resistance, low temperature resistance, and can be used in -40℃~-50℃ area .

5. 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 pressure, strong explosion-proof force, and can be used with porcelain and glass insulators interchange.
