    Jun 13, 2016A major reason is the cost. With higher voltage comes less copper for wiring, but more money for electrical equipment—it’s a balancing act. Another reason is the length of the lines. For longer power lines, it makes sense to use higher voltages, but that comes with greater wire spacing.
