11 kV power lines (UK)

These are the power lines typically used to feed villages and farmhouses (in some cases the final leg may be 400 V or 230 V). 11 kV power lines are single circuit on wood poles. Terminal poles with ceramic insulators always have one or two discs; those with three discs will be 33 kV. Unlike with 33 kV and above, junctions and circuit breakers are common. Terminal poles frequently feature a transformer, whereas higher voltage lines are transformed at substations.
