Resin-insulated Dry-type Transformer

Up to 38.5kV / 25,000kVA epoxy resin-insulated dry-type transformer with vacuum-cast windings, featuring low loss, flame retardancy and strong short-circuit resistance.

This series covers rated voltage up to 38.5kV and capacity up to 25,000kVA. Windings are vacuum epoxy-cast with copper or aluminum options. The CRGO silicon steel core adopts 45° mitered joints and 5-step lap structure for low loss. Rubber cushion supports deliver excellent vibration damping and short-circuit withstand performance. It features flame retardancy, low noise, maintenance-free operation, strong overload capacity and reliable insulation under over-voltage.
