Chinese insulator exporting influenced by exchange rate
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.
PIN TYPE INSULATOR
According to materials, pin type insulator can be divided into composite pin type insulator and porcelain pin type insulator.
Composite Railway 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
Development of Composite Insulators for Overhead Lines
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

As a professional manufacturer of composite tie top line post insulator, Orient power can also produce other kinds of composite insulators. Such as composite post insulator, composite cross arm insulator, composite railway insulator, composite pin insulator, long rod insulator and so on.

The materials of the composite tie top line post insulator:
Weather sheds and sheath material of the composite tie top line post insulator is 100 % silicone based polymer material.

End fitting material is forged steel; hot-dip galvanized and shall be permanently sealed to prevent moisture and foreign materials from entering the end fitting-rod interface.

Rod material is vinylester or epoxy with an electrical grade glass fiber matrix and manufactured by pultrusion processing.

The insulators is equipped with aluminum grading/corona rings and/or arching horns, which can be installed by hot stick method or removed without disassembling the insulator and hardware assembly.

composite tie top line post insulator

The design test and sample test for the composite tie top line post insulator:
Design tests: Tests on interfaces and connections of end fittings, Tracking and erosion test, Tests on core material, Product specific pre-stressing for IEC 62217,Sudden load release, Thermal-mechanical pre-stress, Assembled core load-time tests, Test specimens, Mechanical load test, Type tests, Electrical tests, Damage limit proof test and test of the tightness of the interface between end fittings and high voltage insulator housing.
