3-Phase Dry Type Transformer Class H Insulation

This product is a high performance, high safety, environmentally friendly dry-type transformer independently developed by our company with reference to the German MORA technology.
This product is a high performance, high safety and environmental protection dry-type transformer developed by our company with reference to German MORA technology.
It is suitable for high fire protection requirements, large load fluctuation and dirty and humid environment. For example, it can be used in airports, power plants, metallurgical plants, and other industries:
Airport, power plant, metallurgical operations, hospitals, high-rise buildings, shopping centers, densely populated areas and other places.
In special environments such as airports, power plants, metallurgical operations, hospitals, high-rise buildings, shopping centers, densely populated areas, and oil and chemical plants, nuclear power stations, and nuclear submarines.
Special environments


  • Product Code: SG(H)B10-100~2500/10

Performance Characteristics

Good heat dissipation conditions, long thermal life, excellent overload capacity. In 120% long-term overload, IP45 conditions without forced air cooling, can be long-term full-load operation. -Extremely high safety and flame retardant performance, no smoke generation under 800℃ high temperature and long time burning.
-Extremely strong resistance to thermal shock (can be immediately added to the full load at -50 ℃).
-100% waterproof sealing, excellent waterproof and moisture resistance.
-Unique coil structure and strong field calculation, so that the product is almost no local discharge generation.
-Low loss, remarkable energy saving effect.
-Insulation materials and copper wires can be easily separated and recycled after the life span, without polluting the environment.
