Product Introduction

Dry-type transformers are widely used in local lighting, high-rise buildings, airports, terminal CNC machinery equipment and other places. Simply put, dry-type transformers refer to transformers whose cores and windings are not immersed in insulating oil.

Structural features
Because dry-type transformers have the advantages of strong short-circuit resistance, small maintenance workload, high operating efficiency, small size, and low noise, they are often used in places with high performance requirements such as fire prevention and explosion protection.
1. It is safe, fireproof, pollution-free, and can be directly operated in the load center;
2. Using domestic advanced technology, high mechanical strength, strong short-circuit resistance, small partial discharge, good thermal stability, high reliability and long service life;
3. Low loss, low noise, obvious energy-saving effect, maintenance-free;
4. Good heat dissipation performance, strong overload capacity, and capacity operation can be increased when forced air cooling;
5. Good moisture-proof performance, adapt to high humidity and other harsh environments;
