China is an insulator manufacturer and Chinese insulator exporting occupy very high portion in worldwide insulator market. Recent years the exchange rate US dollar to RMB has changed a lot which influence Chinese insulator exporting.
According to materials, pin type insulator can be divided into composite pin type insulator and porcelain pin type insulator.
Composite railway insulator is also called Composite Railway Insulator, Silicone Rubber Railway Insulator, or Polymer Railway Insulator. Orient Group can provide composite railway insulator
In 1980, Furukawa Electric developed composite insulators that had advantages of light weight and flexibility. And in 1994 the voltage of composite insulator was extended to 275kV with the length 7m/unit--the world’s largest
porcelain pin type insulator,distribution ceramic pin insulator
Porcelain pin type insulator or distribution ceramic pin insulator definition:
Porcelain pin type insulator, also called distribution ceramic pin insulator, consists of a single piece of ceramic or maybe two pieces of ceramic components permanently assembled together by cement. Porcelain pin type insulator is mounted rigidly on a supporting structure by an insulator pin or insulator spindle. Unless otherwise stated, this term does not include the insulator pin.
