Overview
Composite insulators can effectively utilize open circuit voltage and transmission in narrow corridors. Technological transformation for urban networks. It can reduce the height of the tower and save a lot of manpower, material and financial resources. Due to its high flexural strength, it can prevent the cascading failure of the porcelain crossarm. It is an irreplaceable product of the porcelain crossarm. It has the characteristics of small size, light weight, and shock resistance. , and does not require manual cleaning, which provides a guarantee for safe operation.
The high-strength composite cross-arm insulators designed and produced by our company operate safely in substations, effectively solving the shortcomings of porcelain cross-arms that are prone to pollution flashover and safety accidents, and are well received by users. According to the actual situation (especially when replacing the original porcelain cross-arm), we provide users with solutions, design and produce different bases and metal accessories for fixing wires to be installed on the composite cross-arm, we design and produce high-voltage grade high-strength composite cross-arms Cross arm insulators and composite column insulators have passed the comprehensive inspection of the National Insulator Arrester Quality Supervision and Inspection Center and have been well received.
Features
1. Superior electrical performance and high mechanical strength. The tensile and flexural strength of the epoxy fiberglass drawing rods carried inside is twice that of ordinary steel and 8-10 times that of high-strength porcelain materials, which effectively improves the reliability of safe operation.
2. Good anti-pollution property and strong anti-pollution flashover ability. Its wet withstand voltage and pollution voltage are 2-2.5 times that of porcelain insulators with the same creepage distance, no cleaning is required, and 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 greenhouse 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. Good sealing performance and strong resistance to electrical corrosion. The anti-leakage and tracking of the shed material can reach TMA4.5 level. Has good aging resistance, corrosion resistance and low temperature resistance. It can be used in the range of -40℃~+50℃.
6. 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 used interchangeably with porcelain and glass insulators.
