Compared with oil-immersed transformers of similar products, this series of transformers, using advanced production equipment, adopt new technology of coil epoxy vacuum pouring and CD iron core, obviously reduce weight and volume. The insulation strength and moisture resistance are improved in quality, and the magnetic leakage is weakened effectively.

This series of products has the characteristics of light weight, small volume, beautiful shape, stable performance, easy to use and carry, especially suitable for field operation. It is a new type of AC / DC dual-purpose high-voltage test transformer in China. This series of generators is suitable for all kinds of high voltage power supply in power system and electric power users to test the insulation performance of various electrical equipment, DC high voltage and small current of electrical products.
