Introduction of A and B
As the only one of applying the SF6 gas-isolated technology, it replaces the oil-immersed transformer by the small volume, light weight, stabilization, and little-current of partial discharge. The voltage capacity of single transformer can even reach 1000kVA/ 1000kV. It’ s also environment-friendly, free of maintenance, long using term, and excellent performances.
As the national new product and patented product, it’ s particularly applicable in partial discharge test of 110kV and 220kV electrical devices.

And it’ s the new generation of ideal high-voltage testing devices with two kinds of products, the metal & dielectric shell and the singe – stage & cascade voltage. It can also be used in the environment of cold and high latitude districts, like altiplanocie
