Composite post insulator
Composite post insulators can effectively use narrow corridors to open voltage and transmit electricity. They are suitable for urban network technical transformation, can reduce the height of pole towers, and can save a lot of manpower, material and financial resources. Because of its good bending strength, It can prevent the cascading fracture accidents that are easy to occur in porcelain cross-arms, and is an irreplaceable product for porcelain cross-arms; it is small in size, light in weight, good in shock resistance and impact resistance, and does not require manual cleaning, providing protection for safe operation. This product adopts integral rod design, compact structure, good quality, and the weight is 1/10 of the same level of porcelain and glass insulators. It is very convenient for transportation and installation.

The function and characteristics of composite post insulators
Composite post insulators can effectively use narrow corridors to open voltage and transmit electricity. They are suitable for urban network technical transformation, can reduce the height of pole towers, and can save a lot of manpower, material and financial resources. Because of its good bending strength, It can prevent the cascading fracture accidents that are easy to occur in porcelain cross-arms, and is an irreplaceable product for porcelain cross-arms; it is small in size, light in weight, good in shock resistance and impact resistance, and does not require manual cleaning, providing protection for safe operation. This product adopts integral rod design, compact structure, good quality, and the weight is 1/10 of the same level of porcelain and glass insulators. It is very convenient for transportation and installation.
Suitable for dirty areas, high mechanical tensile loads, large spans and compact lines. Pollution flashover voltage is 30%-50% higher than that of porcelain and glass insulators of the same level. The performance is stable under the ambient temperature of -60 degrees - +200 degrees; the non-breakdown design is adopted, and there is no need to measure the zero value during operation. Superior electrical performance and good mechanical strength. The tensile and flexural strength of the epoxy glass lead rods carried inside is 2 times higher than that of ordinary steel, and 8~10 times that of high-strength porcelain materials. The excellent effect improves the quality of safe operation.
Strong pollution resistance, strong anti-pollution, strong anti-pollution flashover, its wet withstand voltage and pollution withstand voltage are 2~2.5 times that of porcelain insulators with the same creepage distance. And it does not need to be cleaned, and it can run safely in places with heavy pollution.
Small in size and light in weight (only 1/6~1/9 of porcelain insulators of the same voltage level). Light in structure, easy to transport and install.
Composite post insulator characteristics:
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, aging resistance, tracking resistance and resistance Electric corrosion resistance, high tensile strength and bending strength, good mechanical strength, strong impact resistance, shock resistance and brittle fracture resistance, light weight, easy installation and maintenance, and the installation dimensions of the upper and lower ends are in line with the corresponding The installation dimensions of the porcelain post insulators are the same and can be used interchangeably.
