CEEG 1250VA Dry-Type Transformer
Adopting resin-cast insulation and an oil-free structure, the transformer is suitable for indoor installations and areas with high personnel density. It emphasizes fire safety, environmental protection with zero leakage risk, and low maintenance requirements. Optional natural air cooling or forced air cooling configurations are available to meet different load conditions and continuous operation demands. The 1250 kVA dry-type transformer is better suited for projects with increasing load demand and higher peak loads, providing sufficient capacity margin for future expansion and system scalability.
