Dry test transformer

Compared with oil-immersed transformers of the same kind, the new technology of epoxy vacuum pouring and CD core with coil winding is adopted in this series of transformers. The weight and volume of transformers are obviously reduced, the insulation strength and humidity resistance are improved in quality, and the impact ability of transformers to withstand test short circuit current is greatly strengthened by effectively weakening magnetic leakage. Our company can customize any parameters of non-standard pressure products and equipment!
