Gas Insulated Bushing Used For Vacuum Recloser / White / korea / Japan
Product Description:
Porcelain insulator is made up of electric porcelain and was the earliest insulator .the process technology is easy. Porcelain insulator have a lot of advantages ,such as 1the good feature of insulation, 2climate change 3heat resistance, 4assembly flexible. it wide use in the circuit of various voltage level.
The insulator material is easy to dirty in an unsheltered area. and after dirty ,the insulation will reduce substantially.
Finally ,it can lead to creepage, and have an accident. porcelain insulator looks smooth in appearance, so it is not easy to scalling relativity . porcelain materials have the nicest feature of aging resistance. not like other composite materials.
They are very easy to aging in Atmosphere. It has some of corrugations in surface and makes the porcelain insulator more useful. 1Firstly ,it can block the flashover. 2secondly, when it rains ,it also can block the flow.
Sewage can't run from top to bottom.it avoid short circuit efficiently. 3thirdly, when dustiness falling, it will non -uniform distribution.so the compressive strength has been improved.

Applications:
Gas insulated porcelain bushings are used for SF6 gas insulated load break switch.
Competitive Advantages:
1. The porcelain glaze are hard and shinning , it has very good self-cleaning advantage . it is easy for maintenance .
2. the insulator are non-punctured product . so the transmission line maintain will be much more easier .
3. we offer 1 years up to 2 years quality guarantee for our product .
4. OEM design are available.
