The rod-shaped suspension composite insulator pillar composite insulator is composed of three parts of glass fiber epoxy resin drawing rod, silicon rubber umbrella skirt and fittings.
Different types of rod-type suspension composite insulators have different functions, and the structure height and creepage distance are also different. The composite insulators are mainly used for transmission lines and have good hydrophobicity, aging resistance, tracking resistance and tracking resistance. Corrosiveness, high tensile strength and bending strength, high mechanical strength, good impact resistance, shock resistance and brittle fracture resistance, light weight, easy installation and maintenance, the installation size of the upper and lower ends and corresponding Porcelain insulators have the same installation dimensions and can be used interchangeably.
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.
