GB20o52-2020 standard energy-saving_product energy-eficiency two-stage dry-type transformer has the advantages of strong short-circuit resistance, small maintenance workload, high operating efficiency, smallsize,low noise, and is often used in places with high performance requirements such as fire prevention and explosion protection. Safe, fireproof, pollution-free, and can be directly used for high load power consumption;
Adopt domestic advanced technology, high mechanical strength, strong short-circuit resistance, small partial discharge, good thermal stability, high reliability and long service life: 
Low loss,lownoise,obvious energy-saving effect,maintenance-free;
Good heat dissipation performance, strong overload capacity, and short-term over-capacity operation under forced air cooling;
It has certain moisture-proof performance, and can operate in harsh environment with high humidity;
The hand transformer can be equipped with a complete temperature detection and protection system. Intelligent signal temperature control system is adopted, which can automatically detect and patrol display the working temperature of each three-phase winding, automatically start and stop the fan, and have alarm, trip and other function settings;
Small size, light weight, small floor space and low installation cost.
