Cast Resin Transformer

kVA Capacity Range: Up to 6300 kVA
Voltage Range: Up to 35 kV
Compliant with IEC Standards
Customizable solutions available according to customer requirements

Cast resin transformer is a type of power transformer where both the windings and the core are encapsulated with epoxy resin. Pouring epoxy resin enhances the insulation performance and mechanical strength of the transformer, while preventing loose winding and deformation, and enhancing the transformer’s short-circuit resistance and durability.

Product Features:

1.Low energy consumption, low noise, maintenance-free, pollution-free, can be directly installed in load centers.

2.Strong short-circuit resistance, low partial discharge, high reliability.

3.Excellent heat dissipation capability, capable of operating at 140% rated load under forced air cooling conditions.

4.Corrosion-resistant, moisture-resistant, flame-retardant, fire-resistant, capable of operating in high humidity and other harsh environments.

5.Equipped with intelligent temperature control device, providing centralized monitoring and control, ensuring reliable operation of the transformer.
