NAYDQSeries Gas type Testing Transformer
Product characteristics
1,The gas type testing transformer is in small size and light weight ( it is lighter 40% to 65% than the same level of oil-immersed testing transformer)
2,Clean, greaseless, do not need maintenanceafter use
3,Weather-proof , on site testing without standstill
4,The dielectric strength is higher than the oil type testing transformer, and the corona is minimal
Introduction of test transformer
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’sthenanao electric companynew 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
