The Structural Composition and Applicable Fields of Polymer Insulators

Composite/Polymer insulators  adopt an integral rod design, with a compact structure, high quality, and a weight of 1/10 that of porcelain and glass insulators of the same grade, making transportation and installation extremely convenient. Small size, light weight, and lightweight structure, making it easy to transport and install.

The composite insulator consists of three parts: glass fiber epoxy resin pull rod, silicone rubber umbrella skirt, and hardware. Composite post insulators can effectively utilize narrow corridors for voltage transmission and are suitable for urban power grid technology transformation. They can reduce the height of towers and save a lot of manpower, material resources, and financial resources. Due to their high bending strength, they can prevent the occurrence of continuous fracture accidents in porcelain cross arms, making them an irreplaceable product for porcelain cross arms; Small size, light weight, strong shock and impact resistance, no need for manual cleaning, providing guarantee for safe operation.

Suitable for dirty areas, high mechanical tensile loads, large spans, and compact lines. The pollution flashover voltage is 30% -50% higher than that of porcelain and glass insulators of the same grade. Stable performance at ambient temperatures ranging from -60 ° C to+200 ° C; The non breakdown design adopted eliminates the need to measure zero values during operation. The electrical performance is superior, and the mechanical strength is high. The tensile and Flexural strength of the epoxy glass draw bar loaded inside is 2 times higher than that of ordinary steel, and 8~10 times higher than that of high-strength porcelain material, effectively improving the reliability of safe operation.

Composite insulators have good pollution resistance, anti pollution performance, and strong anti pollution flashover strength. Their wet and pollution withstand voltages are 2-2.5 times that of porcelain insulators with the same creepage distance. And without the need for cleaning, it can operate safely in heavily polluted areas.
