Typical transmission voltages include 115 kV , 138 kV, 230 kV , 345 kV, 500 kV, and 765 kV. Sub-transmission networks, used to transmit power over shorter distances, use 34 kV, 46 kV, or 69 kV. Before reaching the distribution network, “step down” substations are needed to reduce voltage. Typical transmission voltages include 115 kV , 138 kV, 230 kV , 345 kV, 500 kV, and 765 kV.
