Resin-Insulated Dry-Type Transformer
Request a Quote
Yawei resin-insulated dry-type transformers have five series. The dry-type transformer applies copper windings to low-voltage coils, which solves a range of problems from strong short-circuit stress, ampere-turn imbalance, poor heat dissipation to unstable manual welding quality. The resin-insulated transformer can be used in high-rise buildings, subways, airports, power plants and so forth, especially suitable for scenarios with high fire-proof standards.
Features
- The coil ends are cast with resin and not prone to moisture and dirt;
- The copper leads are automatically welded.
