Cast Resin Encapsulated Transformers
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 epoxy resin or impregnated with H class polyester resin with high cementation.
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.

Offshore and onshore, an exclusive product for all types of marine installations Transformers and reactors for marine applications are distinguished in two different types of installations: offshore and onshore. For each of these installations, additional distinctions can be made depending on the application and use. GBE develops these exclusive products in cast resin, dry type […]
GBE celebrates 20 years of business. We have achieved excellent results thus far, but we’re not done yet. There are numerous projects currently under way – not only in terms of the production process, with new investments especially in the power division – but also in regards to certifications in new markets where specific […]
Tripled production capacity for power transformers GBE produces air-insulated, cast resin and oil-filled, special and distribution transformers and reactors. In recent years we’ve increased the number of units produced for each type of transformer and reactor, as well as the average power, following an increase in orders for the power division, which is steadily […]
