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.

C. Control Cabinet ( Console) and Numerical Control Console for Testing Transformer
As upgrade replacement of high-voltage testing equipment, this kind of testing transformer console applies the automatic control of microcomputer, which is especially useful in automatically controlling system of high-voltage tester of non-partial discharge. It is the first testing console ever made in china, which makes high-voltage testing easier to carry out.
