Model Meaning

Product Description

Class H insulation:
        The insulation and heat resistance of dry-type transformers are: B, F, H, C, etc. The heat resistance temperature is: 130C, 155C, 180C, 220C. This product adopts DuPont new materials and new processes. The insulation resistance of the SG (B) 10 dry-type transformer of the original product has reached H level, and the insulation resistance of key parts The thermal level has reached C level.
Hottest temperature (for reference):

Reliable

The special coil design, process and materials of SG (B) 10 new products make the product have good three-proof performance (moisture-proof, mildew-proof, smoke-proof), more able to withstand thermal shock, never crack and no partial discharge. Take N0mex as The basic insulation system maintains good electrical and mechanical properties throughout the life of the transformer. N0mex products are not prone to aging, shrinkage and compression resistance, and have strong elasticity, so they can ensure that the transformer coils even after years of use. The structure remains tight and can withstand short circuit pressure.

Strong overload capacity

SGB10 new products adopt new structure, new materials, new processes, good heat dissipation conditions, long thermal life, strong overload capacity, and can operate reliably for a long time under 120% overload. In the IP23 environment, there is no need for forced air cooling, and it can still run at full load for a long time.

Conditions of Use

It is the same as 12 of GB6450-1986 "Dry Power Transformers". When the environmental high temperature is> 40C and the altitude is> 1000m, it will be revised according to the relevant international regulations, and the user is required to put forward when ordering.
