Wholesale Composite Post Polymeric Suspension Insulator 33kv Pin Insulator

Product Description

Wholesale Custom Made Composite Post Insulator 33kv Pin Insulator

Product Description

Our electrical power composite polymeric suspension insulators are core supporting products for high-voltage power transmission and distribution systems, widely used in high and ultra-high voltage power lines and substation projects. Made of high-quality integrated polymer composite materials, they have obvious advantages over traditional ceramic and glass insulators, featuring light weight, anti-pollution flashover, aging resistance and shatterproof performance. With stable insulation, high and low temperature resistance and acid-base corrosion resistance, they adapt to complex outdoor environments such as plateaus, foggy areas and coastal high salt-fog regions. Strictly tested with high voltage withstand and mechanical load, the insulators own high mechanical strength and easy installation. We support customized specifications and deliver standardized, cost-effective and reliable insulation solutions for global power projects.

The Polymer Insulator are made of glassfiber epoxy core rod, silicone rubber shed and metal fittings.

 

The silicon rubber shed adopt the whole packing pressure technique, and then to solve the key problem - interface electric spark puncture, which would affect the reliability of composite insulator.

 

Connection of the glassfiber rod and metal fittings, adopts the pressure welding technique of the international advanced level, and have the full automatic sound wave detection of defects system, high intension, beautiful outline, small volume, light weight, and the metal fitting of galvanization can corrosion prevention and exchange used with porcelain insulator.

 

This product is reliable structure, can't damage the core rod, and take full advantage of the mechanical strength.

 

 The dimension can be customized as per client's requirement.
