The composite pillar 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 and financial resources. Due to its high bending strength, it can prevent the occurrence of porcelain crossarms.
It is a product that cannot be replaced by porcelain crossarms; it is small in size, light in weight, strong in shock and impact resistance, and does not require manual cleaning, which provides a guarantee for safe operation.
Suitable for dirty areas, high mechanical tensile loads, large spans and compact lines. The pollution flashover voltage is 30 percent -50 percent higher than that of the same grade of porcelain and glass insulators. The performance is stable under the ambient temperature of -60 degrees to plus 200 degrees; the non-breakdown type design is adopted, and there is no need to measure the zero value during operation.
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 ceramic materials, which effectively improves the reliability of safe operation.
Good anti-pollution performance, good anti-pollution performance, strong anti-pollution flashover, its wet withstand voltage and pollution withstand voltage are 22.5 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 and light weight (only 1/61/9 of the same voltage level porcelain insulator). Lightweight structure, easy to transport and install.
Different types of composite post insulators have different functions, and the structure height and creepage distance are also different. Composite post insulators are mainly used in substations and have good hydrophobicity, anti-aging, tracking resistance and electrical corrosion resistance.
It has high tensile strength and flexural strength, high mechanical strength, good impact resistance, shock resistance and anti-brittle fracture performance, light weight, easy installation and maintenance, and the installation dimensions of its upper and lower ends are the same as the corresponding porcelain pillar insulators. The installation dimensions are the same and can be used interchangeably.
