Solution

AC type current is carried through the transmission wires.

A transformer is an electrical device that transfers energy from one circuit to another by magnetic coupling with no moving parts. Transformers alone CANNOT convert AC to DC or DC to AC; they cannot change the voltage or current of DC; they cannot change the AC supply frequency
