Product Description

Our factory can produce voltage with 500kV and below, capacity 1000MVA and below series oil immersed power transformers.
digesting the advanced technology at home and abroad, combined with the advanced technology at home and abroad and our company’s experience in producing power transformers for many years,
Through optimization and innovation, we have successfully produced a series of power transformers with low noise, low loss, low partial discharge and high short-circuit resistance,
Fully comply with and superior to national standards and International Electrotechnical Commission recommended standards.

Transformer Main functions and characters:

Bell type tank and the wave form shell.; Increase the strength of oil box, beautiful appearance;

Core is with D shape yoke, 45 angle seaming;

Core and oil box are well fixed and well protected on moving;

Reasonable wrapping method, in the interior and exterior structure of coil; Use support; Hard paper bucket

between coils increases the capacity of anti-shortcut;

Advanced assembling method such as cold pressing and welding technology, installing with sets of coil, paper

bucket production.
