NAYDJ Series Oil type/ Gas type/ Dry type Testing Transformer NAYDJ 油浸/干式/充气式试验变压器
产品简介
NAYDJ系列油浸式/充气式/干式试验变压器（以下简称试变）又称升压器，它是发电站、供配电系统及科研单位等广大用户的基本试验设备。用于对各种电器产品、电气设备、绝缘材料等进行规定电压下的绝缘强度试验，考核产品的绝缘水平，发现被试品的绝缘缺陷，衡量承受过电压的能力。
产品特性
NAYDJ系列 油浸式试验变压器
1、NAYDJ系列油浸式试验变压器选材优良，质量可靠，年稳定性好。
2、电压裕度大，电晕声小，局放小。
3、采用新式绝缘材料，体积小，重量轻。
NAYDJ Series Oil type/ Gas type/ Dry 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

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 reces 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
