Transmission Lines

Transmission Lines is a polyline dataset representing the power lines that are used to transmit electric power across NZ, usually from a power generating station to main substations that make up the National Grid. They are comprised of overhead and underground conducting lines of either copper or aluminium. In NZ these High Voltage (HV) transmission lines operate at kiloVoltages (kV) of 33 , 66, 110, 220 AC and 350 DC. (Transmission Line is not a topological network.) (Spans are a sub-set of the Transmission Lines data set. Spans record the structure from / to and the length between the structures). The Transmission Lines dataset is updated ad-hocly.
