Dry type test transformer DYGS-5kVA/50kV

1、 Product introduction

This series of transformers, using advanced production equipment, adopt the new process of coil epoxy vacuum pouring and CD type iron core. Compared with oil immersed transformers of the same kind, it significantly reduces the weight and volume, improves the insulation strength and moisture resistance in quality, and effectively weakens the magnetic leakage, thus greatly strengthening the impact capacity of the transformer to withstand the test short-circuit current.

This series of products are light in weight, small in size, beautiful in shape, stable in performance, convenient in use and portability, especially suitable for on-site operation. It is a new type of AC/DC dual purpose high-voltage test transformer updated in China. This series of generators are applicable to the high-voltage power supply in various voltage systems or devices of power systems and power users to test the insulation performance of various electrical equipment on site, DC high-voltage small current of electrical products.
