Our dry-type power transformers are a kind of power transformers, whose cores and windings are never immersed in mineral oil. They are widely used in shopping mall, buildings, airports, wharfs and substations for local lighting and electric energy transformation between the generator and distribution primary circuits.

Dry-type power transformers are also suitable for various switchgears applied to power system. Those up to 10kV can be installed in 650-1200 mm wide switchgears, up to 20kV in a 1000mm wide switchgears and 35kV in 1400 ~ 1600 mm wide switchgears.

1. Low no-load loss and energy conservation.

2. Low noise and environmental protection.

3. Long service lifetime and safe and reliable performance.

4. Reasonable and aesthetic structural design and exquisite manufacture craftsmanship.

5. A full variety of accessories and appropriate protection measures. 

Note: Those listed in the table above are the routine parameters for reference. Besides, products could be redesigned according to clients' actual demands.
