Different types of pillar composite insulators have different functions, and the structural height and creepage distance are also different. The pillar composite insulators are mainly used in substations, which have good water repellency, aging resistance, tracking resistance and electrical corrosion resistance. It has high tensile strength and flexural strength, high mechanical strength, good impact resistance, shockproof and anti-brittle performance, light weight, convenient installation and maintenance, and the installation dimensions of the upper and lower ends and the corresponding porcelain post insulators. The installation dimensions are the same and can be used interchangeably.

The composite post insulator can effectively use the narrow corridor to open and transmit power. It is suitable for urban network technical transformation, can reduce the height of the tower, can save a lot of manpower, material and financial resources. Because of its high bending strength, it can prevent the porcelain cross arm from appearing easily. The cascade fracture accident is a product that cannot be replaced by porcelain cross-arm. It is small in size, light in weight, strong in shock resistance and impact resistance, and requires no manual cleaning to provide safe operation. This product adopts integral rod design, compact structure, high quality and weight of 1/10 of the same grade 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. The flashover voltage is 30%-50% higher than the same grade porcelain and glass insulators. Stable performance at -60 degrees - +200 degrees ambient temperature; non-breakdown design, no need to measure zero value during operation. Excellent electrical performance and high mechanical strength. The tensile strength of the internal load-bearing epoxy glass rod is 2 times higher than that of ordinary steel, which is 8~10 times higher than that of high-strength porcelain material, which effectively improves the reliability of safe operation.

Good anti-fouling performance, good anti-fouling performance, strong anti-pollution flash, and its wet withstand voltage and pollution withstand voltage are 2~2.5 times of the same creepage porcelain insulator. And no need to clean, can run safely in heavy pollution.

Small size and light weight (only 1/6~1/9 of the same voltage grade porcelain insulator). Lightweight structure for easy transportation and installation.
