I. Product Introduction
This series of test transformers, utilizing advanced production equipment, adopts new processes of coil winding epoxy vacuum casting and CD-type iron core. Compared with similar products like oil-immersed test transformers, it significantly reduces weight and volume, improves insulation strength and moisture resistance in quality, and effectively weakens magnetic flux leakage, greatly enhancing the transformer's ability to withstand short-circuit current impacts during tests.
This series of products features light weight, small size, attractive appearance, stable performance, and portability, especially suitable for on-site operation. It is a new generation of AC/DC dual-purpose dry-type test transformers in domestic replacement. This series is suitable for insulation performance testing of various electrical equipment in power systems and various power users, as well as high-voltage power sources in various voltage systems or devices for DC high-voltage and low-current applications of electrical products.
