Not sure I understand what you are saying. Unless the wrong terms are
being used, but transformers "hate" DC. Plus also, think of voltage like
water pressure: i.e. the higher the pressure the further the water
travels. Also consider the Litz effect; higher frequencies tend to
travel along the outer surface of the conductor(s), hence, multi
strand cable etc.
