Product details

Oil-immersed transformer

Oil-immersed transformers are voltage conversion devices that utilize oil cooling to reduce transformer temperature. We offer high-voltage ratings up to 38.5kV and rated power capacities of up to 31,500kVA. Our products hold ISO and CE certifications, and our team is proficient in international standards including IEEE, CSA, DOE, and NEMA. Featuring high-permeability silicon steel laminations and H-class insulation materials, these transformers deliver low losses and robust short-circuit resistance. They operate reliably in environments ranging from -25°C to 40°C, making them suitable for complex power applications such as renewable energy plants and data centers.

Routine tests of transformer include：

1.Winding resistance test of transformer

2.Transformer ratio test

3.Transformer vector group test

4.Measurement of impedance voltage/short circuit impedance (principal tap) and load loss (Short circuit test)

5.Measurement of no-load loss and current (Open circuit test)

6.Measurement of insulation resistance

7.Dielectric tests of transformer.

8.Tests on on-load tap-changer.

9.Oil pressure test on transformer to check against leakages past joints and gaskets
