Suspension type composite insulator pillar composite insulator is composed of glass fiber epoxy resin pull-out rod, silicon rubber umbrella skirt and fittings.
The rod-shaped suspension composite insulator can effectively utilize the narrow corridor open-pressure power transmission. It is suitable for the technical transformation of the city grid, can reduce the height of the tower, and can save a lot of manpower, material and financial resources. Due to its high bending strength, it can prevent porcelain horizontal Insulators are prone to cascading fracture accidents and are products that cannot be replaced by porcelain insulators; they are small in size, light in weight, strong in shock resistance and impact resistance, and do not require manual cleaning, providing guarantee for safe operation. This product adopts the overall rod design, compact structure, high quality, weight is 1/10 of the same grade porcelain and glass insulators, transportation and installation is extremely convenient.
Suitable for dirty areas, high mechanical tensile loads, large spans and compact lines. Pollution flashover voltage is 30%-50% higher than porcelain and glass insulators of the same grade. The performance is stable under the ambient temperature of -60 degrees to +200 degrees; the non-breakdown design is adopted, and zero value is not required during operation. The electrical performance is superior, the mechanical strength is high, the tensile strength of the epoxy glass pull-out rod carried inside is 2 times higher than that of ordinary steel, and 8-10 times that of high-strength ceramic materials, which effectively improves the reliability of safe operation.
It has good anti-pollution performance, anti-pollution performance, and strong anti-pollution flashover strength. Its wet withstand voltage and pollution withstand voltage are 2~2.5 times of the same creepage porcelain insulator. And it does not need to be cleaned, and can be safely operated in heavy pollution.
Small size and light weight (only 1/6~1/9 of porcelain insulators of the same voltage level). Lightweight structure, easy to transport and install.
Executive standard:
The rod-type suspension composite insulator model is compiled according to the provisions of JB/T9683-1999 (Insulator product cold preparation method); the configuration parameters are implemented in JB/T5892-1991 (technical conditions for organic composite insulators for high-voltage lines) and JB/T8737-1998 ( Guidelines for the use of composite insulators for high-voltage lines) standard. The important parameters and configuration methods not clearly defined in the above standards are revised and implemented in accordance with the requirements of GB311.1-1997 (Insulation coordination of high-voltage power transmission and transformation equipment) and GB/T5582-1993 (Outside insulation pollution level of high-voltage power equipment).
