The main features:

1、Small size, light weight (compared with the level of voltage, capacity of oil-immersed experiment transformer light 40%-65%).
2、Clean, no oil stain, maintenance-free.
3、Not affected by adverse weather and environmental effects, handling without static testing can be done at the scene;
4、Insulation strength was significantly higher than oil-immersed experiment transformers, partial discharge <3pC.
