Underground lines are used to transport power through populated areas, underwater, or pretty much anywhere that overhead lines can't be used. They are less common than overhead lines due to heat-related losses and higher cost. Subtransmission lines carry lower voltages (26 kV - 69 kV) to distribution stations, and can be overhead or underground.

If you see a power line tagged with a voltage which isn't in the above table, it's likely to be wrong. (But some offshore wind farms use unusual voltages - most often 150 kV and 220 kV - for their "export" cables.) In the vast majority of cases, if a power line has three wires, it's a single three-phase circuit (circuits = 1, cables = 3).

How Do Wind Turbines Work? | Department of Energy

A wind turbine turns wind energy into electricity using the aerodynamic force from the rotor blades, which work like an airplane wing or helicopter rotor blade. When wind flows across the blade, the air pressure on one side of the blade decreases. The difference in air pressure across the two sides of the blade creates both lift and drag.
