General Features

STD Cast Resin Transformers have at least one of the two windings embedded on an autoclave mould, at vacuum values close to zero with epoxy resin. The other winding can also be cast in H class.

STD Cast Resin Transformers have reached a high degree of reliability thanks to the technological advances in recent years. Our production E2, C2, F1, but also E3 (IEC 60076-16) and C4 (GOST-R), can be used in the presence of a high humidity and pollution rate, low installation temperatures even down to -60°C, therefore eliminating the problems related to the risks of fire and emissions of toxic and harmful substances in case of fire.

As they are entirely built with insulating, flame retardant and self-extinguishing materials, they are completely free from all restrictions that should normally be applied to flammable equipment with a danger of spreading fire. Std Transformer is Design, manufacturing and exporting 53 Countries of The Cast Resin Transformers
