Overhead powerlines come in various forms and sizes from large pylons at thousands of volts to smaller installations – sometimes in rural areas going direct to buildings from roadside poles; overhead power lines for train, tram and trolleybus services are also common in cities.

With the larger lines, the high voltages can cause the electricity to arc if a conductor comes to close, while with the lower voltage direct contact can result in fatal electrocution and damage to equipment.
