Oil-immersed transformers

Oil-immersed transformers are cost-effective, high-stability, and durable power distribution units widely adopted in global power grid and energy projects. Adopting premium insulating oil as the cooling and dielectric medium, they feature outstanding heat dissipation performance, strong overload capacity, low operational loss, and ultra-long service life with simple daily maintenance. With mature electromagnetic structure design and rigorous manufacturing techniques, these transformers deliver continuous, stable, and safe voltage conversion and power transmission for various power systems.

Transformer Capacity Range:
We specialize in medium to large capacity transformers tailored for industrial and utility-scale applications. Oil-immersed Transformers: Minimum capacity of 630 kVA. We have extensive expertise in manufacturing high-capacity transformers above 5000 kVA, offering customized solutions for complex and demanding power systems. Please note: While we are capable of producing low-capacity transformers (below 630 kVA), such as distribution transformers, we do not supply them as standalone products. These are only available as part of a complete solution in combination with medium- or large-capacity transformers.
