May 27, 2020 · While aluminium as a metal is lighter than copper of an equal volume, in the case of distribution transformers, this advantage is nullified by the increased volume (and thus weight) of the conductor, steel core, tank and oil. This often results in the equivalent copper wound transformer actually being lighter. ReferenceDespite design precautionsin oil-insulated transformers are primarily related to arcing between parts inside the transformer tank that are at different electric poten-tials. Such a failure event causes a rapid formation of gas and, as the volume of gas builds up, the pressure inside the tank increases significantly. As the metal tank starts to expand, it will deform and
