Porcelain pin type insulator constituents:
Porcelain is the most frequently used material for porcelain pin type insulators. Porcelain pin type insulator Insulators are made of wet, processed porcelain. The fundamental materials used are a mixture of feldspar (35%), china clay (28%), flint (25%), ball clay (10%), and talc (2%).

The porcelain skirt for porcelain pin insulator provides insulation between the iron cap and steel pin. The upper part of the porcelain is smooth to promote rain washing and cleaning of the surface.

The advantages of porcelain pin type insulator have:
-Most conventional distribution insulator
-Applied standard: ANSI C29.5 / C29.6
-Excellent anti-contamination performance
-Excellent wet AC withstand voltage characteristics under contamination
-High power arc resistively

The quality and overall performance of the grey glazed porcelain pin type insulator sets are tested and proven by many and extensive tests in Orient’s own high voltage laboratory in Africa, China or in various independent accredited laboratories in China. Therefore, Orient grey glazed porcelain pin type insulator sets guarantee safe and reliable transmission system operation over decades.
