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 station post insulator,ceramic solid core insulator
Porcelain station post insulator, ceramic solid core insulator:
Porcelain station post insulator is a high voltage ceramic post insulator for power frequency AC voltage 40.5KV ~ 550KV Outdoor power stations, substations and electrical equipment devices. Porcelain station post insulator provides insulation and support function.
high voltage porcelain station post insulator high voltage ceramic solid core insulator
High voltage ceramic solid core insulator is divided into common type and anti-pollution fog type. Ceramic solid core high voltage insulator has four contamination levels.High voltage ceramic solid core insulator is designed with large and small alternative shed. If there is more spacing between large sheds, the rain can not easily be bridged, and the bid shed also can protect small shed. This way can greatly improve the electrical performance of the ceramic solid core insulator.
Porcelain material is divided into different strength levels, and made by medium aluminum porcelain and high aluminum porcelain separately. All the assembly adopts sand application first. And high strength porcelain adopts compression glaze and compression sand. This improves the strength of the ceramic part cement ability of the porcelain station post insulator.
Solid-core ceramic insulator may be manufactured according to IEC, ANSI, BS and other standards, with cantilever strength from 4kN to 18kN, which is used on 15kV to 750kV station and substation.
