Oil filled transformers

All transformers up to 3150 kVA can be filled without conservator. The outside walls are protected with water resistant paint RAL 7031(approved by ENEL) or RAL 7033 with painting thickness of 100 micron

All transformers up to 3150 kVA are equipped with corrugated tank wall panels. Higher power units use special developed radiators made with cold rolled and laminated steel.

The primary and secondary windings are made with electrolytic aluminum or copper, with insulation in pure cellulose paper or in double enamel for wires of small diameter. These windings are oval or circular section and are a concentric type, coaxial to the core limbs.

GBE S.p.A. produce oil filled transformers for different applications,  particularly for distribution and special apply with the power up to 25 MVA, also with unload tap changer.
