Current: 400A,630A,1250A，2000A，3150A etc

Main Characters：

1、Low-PD（partial discharge）：
PD≤5pC @Um      ;      PD≤10pC @1.5Um   

2、Low Power Factor：
Under voltage 1.05Um/√3        tanδ≤0.40％   Standard≤0.7%

3、Self-owned process of aluminum oil level gauge and flange(Ground tube) manufaturing, nice appearance and fine quality.

4、Test tap：
a、Alumina porcelain will not be damp for reliable insulation.
b、The spring is compressing the earthing devices for reliable grounding and to avoid misoperation.
c、Entire sealing structure to prevent moisture.

5、The sealing structure of the top part, which is patented, can ensure that even if there is undue stress, minor misoperation, it will not lead to  the dangerous water fault.
