Oil Transformers for renewable energy (Wind/PV):

E.M.G. - Transformers are designed and manufactured according to CEI 14-32 and IEC 60076-11 CENELEC HD 428.1 S1. On request, additional standards can be applied.

The core of this transformer consists of grain-oriented magnetic steel, which enables low losses. The joints between the columns and yokes are designed in an angle of 45 °.

The windings are made of electrolytic copper. But upon request also aluminum windings can be used.

The tanks are made ​​of welded steel plate, with reinforcements to prevent oil loss. The tanks are tested for leaks with liquid (UV light inspection). After sandblasting, the tanks are coated inside with a special oil and protective paint the outside with a specific anti-rust paint and enamel RAL 7031st

Brown porcelain insulators for use as the default type usually. On the page, the typology Ms 20/250 UNEL 38128-74, while on the side of the typology UNEL Ns 38128-67 is for the CNR CEI 21001-74 rules applied.

Special terminal strips on the brass side allow modification of the transmission ratio when the transformer is disconnected. E.M.G. Transformers (non-flammable and biodegradable) usually filled with dielectric oil CEI Class 1 with a vacuum treatment, or on request with dielectric silicone oil.

Then the following tests according to IEC EN 60076 CEI 14-4 usually be performed on all transformers.
