NAYDJ Series Oil type Testing Transformer

Product introduction

NAYDJ Series Oil immersed/ Inflatable / Dry Type Testing Transformer (Short for test transformers), also known as booster, it’s the power station, power supply and distribution systems, and research institutes, and other users  basic testing equipment. Used for a variety of electrical products, electrical equipment, insulation materials, etc. which under the specified voltage dielectric strength test, the insulation level of assessment products found to be defective insulation test to measure the ability of withstand over-voltage.

Also called name

High voltage withstand testing equipment; High voltage testing transformer; AC DC high voltage test device; AC/DC hipot test set; Cascade type high voltage testing transformer; Oil-immersed testing transformer; Oil type test transformer; Gas type test transformer, SF6 gas-typed test transformer, SF6 gas-insulated testing transformer; Dry type test transformer

The Characteristics of Series Oil type Testing Transformer

1. Oil type test transformer selected reliable quality and good stability materials.

2. The voltage margin is high, corona sound is small, partial discharge is small.

3. Adopting modern insulating materials, small in size, light in weight

NAYDQ Series 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 maintenance after 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’s the nanao electric company 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
