Pin Type Composite Insulator

Pin Type Composite Insulator

Application for composite insulator:
Polymer pin type insulator is applied to high voltage power line to support conductor and insulate from ground. And composite insulator is used under 35kV distribution line. Since this type insulator has many advantages, now days many countries and areas more and more use this type insulator to displace porcelain or ceramic insulator.

Component of composite pin insulator:
1. The core uses pulling bar made of epoxide reinforced fiber glass, which has good insulation ability, light mass and high intensity and so on.
2. The outer insulation layer is silicon rubber, which formed by high temperature integration pressing and has good sealing ability and high grade of anti-dust, maintenance free and so on.
3. The metal connection adopts pressing technique, which makes the insulator smaller and no damage on the mandrill. It has good sealing ability and is very convenient for installation.
