product description

Feature of Epoxy Resin Cast Dry-Type Distribution Transformer

This series of thin-insulation dry-type distribution transformer with fillers whose winding is encapsulated by epoxy resin are flame-retardant,fire-proof, explosion-proof, maintenance-free, pollution-free, small in size, and can be directly installed at load center. Meanwhile, because of their scientific and reasonable design and casting system, they have the features of low partial discharge, low noise and good heat dissipation, as well as can be operated under 140% of rated load in the condition of forced air cooling. Transformers are equipped with intelligent temperature controller to conduct centralized monitoring and control on them.
