Performance characteristics

DC series high-voltage single-phase dry-type transformers are used in some special workplaces such as hospitals, railways, coal mines, research institutions, and government departments that require high power grid quality. It can be equipped with a complete temperature monitoring and protection system. The intelligent signal temperature control system can automatically monitor and display the respective working temperatures of the three-phase windings, automatically start and stop the fan, and have functions such as alarm and trip settings.

adaptive features

It can directly penetrate into the load center, flame retardant, anti-riot, no pollution to the environment, and high fire rating.

Structural features

Casting with epoxy resin, high mechanical strength, strong ability to withstand short circuit, safe and reliable operation.

Product advantages

low loss

The low loss and energy saving effect are remarkable, and the loss is reduced by about 40% compared with the three-phase dry-type transformer of the same capacity.

low noise

Low noise, small size, light weight, small footprint, easy installation and maintenance-free.

High insulation

Partial discharges are close to zero and insulation levels are high.

low temperature rise

The temperature rise design is particularly low, and the product has a long service life.
