For transmission of electrical energy, this is the way. Voltages should be as high as equipment, costs, and safety practices allow. Let me opine how expensive it was to refit my 80's van electrical system which has its 12v battery in the front to bring enough current to the starter 4 meters away. (Battery relocation isn't an option.) It originally had a piss-poor 14 ga / 1.6 mm wire to feed the starter and the charge battery, and the losses were awful. What it needed was a single 000 ga / 10.4 mm wire for the positive lead, which requires special cutters and special crimpers to create a usable wire. (The body of the vehicle is used for the negative/neutral lead.)
