Porcelain pin insulator,11KV ceramic pin type insulators
Manufacture report covers testing at works supply and delivery of porcelain pin insulator for power lines with a nominal voltage below 36KV. 11KV ceramic pin type insulators are a main type insulator.
11KV ceramic pin type insulators:
The porcelain shall be sound, free from defects, thoroughly vitrified and smoothly glazed. The design of the porcelain pin type insulator shall be such that the stresses due to expansion and contraction in any part of the insulator shall not lead to its deterioration. The glaze shall be brown, white or gray in colors for insulators. The glaze shall cover the entire porcelain surface parts except those areas that serve as supports during firing. The ceramic pin type insulators shall be suitable for use with all Aluminum Conductor or Copper conductor. The insulators should withstand the conductor tension the reversible wind load as well as the high frequency vibrations set due to wind.
