Details of High quality 11kv 380v to 220v dry-type transformer

Characteristics of High quality 11kv 380v to 220v dry-type transformer

Benefits:

1. High mechanical strength and strong short circuit resistance ability;

2. Good moisture resistance and run with 90% humidity;

3. Advanced structure, small dimension, light weight and low partial discharge;

4. High insulation level and equal electric field distribution;

5. maintenance free;

6. Run with 140% rated load under forced air cooling;

7. Fireproof, explosion-proof, pollution-free and low-noise and able to be directly installed in the load center.

Application:

The product has been widely used in places with high fireproofing requirements, such as power transmission and transformation system, high-rise building, commercial center, sport stadium, petrochemical enterprise, metro, station and airport. In China, the epoxy resin cast dry-type power transformer has the richest manufacturing experience and the best running performance.
