产品特性

1、NAYDQ系列充气式试验变压器体积小，重量轻(比同等级油浸试验变压器轻40%-65%)。

2、洁净，无油污，勿需维护。

3、不受恶劣气候环境影响，现场搬运勿须静止即可做试验。

4、绝缘强度明显高于油浸试验变压器，电晕极小。

采用SF6气体绝缘技术。油浸试变的换代产品，体积小、重量轻、不受气候环境变化影响，局部放电量极小，单台容量电压可达1000kVA/1000kV；现场运用勿静止、无油污、免维护、寿命长、性能指标始终良品等优点。产品特别适用于110kV及220kV等级的电力运行设备的局部放电测试。是新一代理想的高压试验装置。产品分金属体和绝缘筒外壳、单台与串级电压两种类型。特别适用于高寒、（高原）高海拨地区和环境使用。

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
