Cast Resin & Dry Type Transformers

MV cast resin transformers have reached a high level of reliability thanks to the latest technologies. The E2, C2, F1 production can be used with high level of humidity and pollution avoiding all the fire risks, the toxic emissions and any harmful substance and it is according to Regulation EN 50451 and EN 50588. Class E3 (IEC 60076-16) can be guaranteed for special applications, such as offshore installations or eolic plants, and class C4 (GOST-R 54827-2011) can be guaranteed for extreme climatic conditions, such as -60° C working temperature. The transformers are manufactured with fire-retardant, insulating and self-extinguishing materials, so they are not exposed to all the restrictions normally applied to the flammable machines where there is fire spreading and propagation danger. The whole GBE production is manufactured with galvanised steel work and class F or H insulating materials, for some applications with pre-impregnation with resin. The windings are vacuum encapsulated with epoxy resin or vacuum class H polyester resin impregnated. The transformers can be supplied with protection enclosure according to the required IP. The protection housings can be supplied in pickled or galvanised sheet for outside installation. GBE products are therefore suitable for installation in hospitals, banks, public buildings, residences, tunnels, on boats, subways, offshore and on shore platforms.
