Custom Dry Type Transformer | Low Loss Epoxy Resin Distribution Transformer

Dry-type transformer is a high-safety, environmentally friendly power distribution transformer without liquid oil inside. It adopts high-quality grain-oriented silicon steel core and high-grade epoxy resin insulated windings, featuring low loss, low noise, stable performance and strong fire resistance.

Compared with oil-immersed transformers, dry-type transformers have no leakage risk, excellent moisture and corrosion resistance, and require almost no maintenance. They are widely used in urban power grids, commercial buildings, industrial workshops, schools, hospitals and indoor power distribution occasions where high safety is required.

We support customized voltage, capacity, protection grade and special size to meet different indoor and outdoor power supply needs.
