Copper's superior connectivity provides high reliability. The problem of winding space is not as acute in transformers as it is in electric motors, which is why the use of aluminium can at least be taken into consideration.In fact the main leakage channel, i.e. the gap between the HV and LV windings, must have a certain size for the following three reasons insulation, limiting the short
