Gyd Dry Type Test Transformer Test Speed: Vary

- Dry Type Test Transformer series produced by our company completely overcome the old-fashioned shortcoming that it is bulky, heavy. Equipped with high-voltage silicon stack produced by our company, the instrument can provide DC high voltage test power supply. Together with the control cabinet (desk), automatic protection micro-ammeter, sphere gap and so on, the instrument especially suits for on-site test and it makes the heavy work become convenient, fast, easy, flexible, and more efficient. Therefore, it is highly praised and appreciated by the customers coming from power systems and large-scale factory and mining enterprisesa
- GYD series product adopts new material and technology to reduce the volume and weight without compromising performance. It adopts coil winding epoxy vacuum casting and CD - type core wound by cold rolled silicon steel, which reduce the magnetic flux leakage. No need silicone stack for DC withstand voltage test, can get the DC only if install the matching DC HV silicone stack into HV end.


1. Small size, light weight, compact structure, no oil leakage, maintenance-free.
2. Wiring is simple and intuitive, easy to use
3. Insulation reliability.
4. With over-voltage protection function.
