Frequently Asked Questions
A: Every transformer will go through full type test and routine test. We provide test report, factory certificate.
A: We adopt high-quality silicon steel sheet to reduce no-load loss. Loss data can be provided according to your required capacity.
A: The tank is made of carbon steel plate, with anti-rust epoxy painting for corrosion resistance. Stainless steel tank is optional.
A: We supply both oil-immersed transformers and dry-type transformers. Oil type is more cost-effective for outdoor use; dry type is for indoor fire-sensitive environment.
Common voltage combinations: 11kV/0.4kV, 15kV/0.4kV, 20kV/0.4kV. We support custom voltage.
A: Our distribution transformers range from 10kVA to 2500kVA. Custom capacity is available upon request.
