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 spool insulator,ceramic reel insulator
Porcelain spool insulator or ceramic reel insulator definition:
Porcelain spool insulator or ceramic reel insulator is an insulator of generally cylindrical form. Porcelain spool insulator has an axial mounting hole and a circumferential groove or grooves for the attachment of a conductor.
