Product Description

The composite cross arm insulator can effectively use the narrow corridor to open the voltage and transmit electricity. It is suitable for the technical transformation of the urban network. It can reduce the height of the tower and save a lot of manpower, material resources and financial resources. Due to its high bending strength, it can prevent the porcelain cross arm from being easy to The cascading fracture accident that occurs is an irreplaceable product of the porcelain crossarm, which is small in size, light in weight, shock-proof and shock-resistant, and does not require manual cleaning, which provides a guarantee for safe operation.
The 220KV high-strength composite cross arm insulators designed and produced by our company operate safely in 220KV substations, which effectively solves the shortcomings of porcelain cross arms that are prone to pollution flashover and cause 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 fittings for fixing wires to fit on the composite cross-arm, we design and produce high-voltage grade high-strength Composite cross arm insulators and composite post insulators have passed the comprehensive inspection of the National Insulator Arrester Quality Supervision and Inspection Center, and have been well received.

Product technical parameters and structure size

Product features and application range

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.

Product Precautions

1.Insulator in the transportation and installation to should take put down gently, and should not be thrown, and to avoid all kinds of miscellaneous pieces of (wire, iron plate, tools, etc.) and sharp hard object collision and friction.
2. When the composite insulator is hoisted, the knot is tied on the end accessories, and it is strictly forbidden to hit the shed or sheath. The rope must touch the shed and the sheath, and the contact part should be wrapped with soft cloth.
3. Do not use the composite insulator as an auxiliary tool for placing (retracting) wires, so as not to damage the insulator due to impact force or bending moment.
4. It is strictly forbidden to step on the insulator umbrella skirt
