Request DatasheetOverview
Our oil-immersed distribution transformers are wound with electrolytic-grade copper or aluminium and assembled in sealed corrugated tanks that need no conservator and lose no oil to breathing. Every unit is routine tested for ratio, vector group, no-load and load losses, insulation resistance and separate-source withstand before dispatch, and is supplied with a full test certificate and rating plate to the ordered specification.
