Re: Enamelled Aluminium Wire
:Never seen it before. Found the secondary of an old microwave oven
:transformer was wound with it. The primary was enamelled copper however.
:I wonder why they used Al.?
Aluminium is cheaper than copper is my guess.
Some years back I did a modification job on the transformers in some Italian
made battery chargers, made for fork lifts, and the transformer secondary
windings were insulated (formvar?) aluminium wire.
