I. Product Introduction
This series of test transformers, utilizing advanced production equipment, adopt new processes of coil winding epoxy vacuum casting and CD-type iron core. Compared with similar products like oil-immersed test transformers, they significantly reduce weight and volume, improve insulation strength and moisture resistance in quality, and effectively weaken magnetic flux leakage, greatly enhancing the transformer's ability to withstand short-circuit current impact during tests.
This series of products features light weight, small size, attractive appearance, stable performance, and ease of use and portability, especially suitable for on-site operations. They are the new generation of AC/DC dual-purpose dry-type test transformers in domestic upgrades. This series is suitable for insulation performance testing of various electrical equipment in power systems and for various power users, as well as for high-voltage power sources in various voltage systems or devices requiring DC high voltage and small current for electrical products.
