GB20052-2020 standard energy-saving product energy efficiency level 1 manual transformer has the advantages of strong short-circuit resistance, small maintenance workload, high operating efficiency, small size, low noise, etc. It is often used in places with high performance requirements such as fire prevention and explosion prevention. It is safe, fireproof, pollution-free, and can be directly operated in high-load electricity consumption;
-Adopting domestic advanced technology, high mechanical strength, strong short-circuit resistance, small partial discharge, good thermal stability, high reliability, and long service life;
-Low loss, low noise, obvious energy-saving effect, maintenance-free
-Good heat dissipation performance, strong overload capacity, and can be operated in short-term over-capacity under forced air cooling;
-It has a certain moisture-proof performance and can operate in harsh environments with high humidity;
-Small size, lightweight, small footprint, and low installation cost.
