Product Description

 

Product Description

     Because the dry transformer has the advantages of strong short-circuit resistance, small maintenance workload, high operation efficiency, small volume, low noise, it is often used in places with high performance requirements such as fire prevention and explosion protection. [7]
1. Safe, fireproof, pollution-free, 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, long service life;
3. Low loss, low noise, obvious energy-saving effect, maintenance-free;
4. Good heat dissipation performance, strong overload capacity, can improve capacity operation when forced air cooling;
5. Good moisture resistance, adapt to high humidity and other harsh environment operation;
6. Dry transformer can be equipped with perfect temperature detection and protection system. The intelligent signal temperature control system can automatically detect and display the working temperature of the three-phase winding, automatically start and stop the fan, and have alarm, trip and other functions.
7. Small size, light weight, less space, low installation cost.
