I suggest you read up on electricity !
The voltage is stepped up with a transformer because the higher voltages are easier to transmit long distances. You can then have a transformer at the recieving end to step it down again.
You are in danger of making yourself look very silly by discussing things like this with an obvious lack of understanding on the subject.
