What are the functions and characteristics of composite post insulators? The composite insulator is made of special steel fittings, the fittings end adopts the labyrinth design principle, multi-layer protection, good sealing performance, to solve the most critical problem of the insulator ---- interface electrical breakdown. The connection between hardware and mandrel adopts the most advanced computer controlled coaxial constant pressure crimping process in the world, and is equipped with automatic acoustic emission flaw detection system to ensure the reliability and stability of the connection between hardware and mandrel. The core rod adopts ERC high temperature acid resistant rod, and the interface between the core rod and silicone rubber is coated with special coupling agent. The umbrella cover adopts a one-time integral molding process under high temperature and pressure, and the two-stage vulcanization process monitored by computer extends the service life of the product.
Composite pillar insulator can effectively use the narrow corridor open pressure power supply, suitable for the technical transformation of the city network, can reduce the height of the pole tower, can save a lot of manpower, material and financial resources, because of its high bending strength, can prevent the porcelain cross arm is prone to cascade fracture accidents, is the porcelain cross arm can not replace the product; Small size, light weight, shock resistance, strong impact resistance, no need for manual cleaning, to provide security for safe operation.
Suitable for dirty areas, high mechanical tensile load, large span and compact lines. The pollution lightning voltage is 30%-50% higher than that of the same grade porcelain and glass insulators. Stable performance at -60 ° C -+200 ° C ambient temperature; Non-disruptive design, no need to measure zero value in operation. Superior electrical performance, high mechanical strength, the tensile and bending strength of the epoxy glass drawing rod is 2 times higher than that of ordinary steel, and 8 to 10 times higher than that of high-strength porcelain material, effectively improving the reliability of safe operation.
Good anti-fouling performance, good anti-fouling performance, strong anti-fouling flashover strength, its wet withstand voltage and pollution withstand voltage for the same climbing distance porcelain insulator 2~2.5 times. And do not need to clean, can run safely in heavy dirt.
Small size, light weight (only 1/6~1/9 of the porcelain insulator of the same voltage grade). Light structure, easy to transport and install.
