HRYDQ (W) Series of High-voltage Tester of Industrial Frequency Non-partial Discharge for Ultra-light-type Gas-filled-type Transformer
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
