Lines and cables
About two thirds of Northern Ireland’s electricity network is overhead. Electricity lines, sometimes called conductors, are carried on wooden poles or towers.
As Northern Ireland has a very spread out population, made up of lots of single homes in the countryside, overhead lines are the cheapest, quickest and most effective to connect them to the electricity network.
In towns or cities, electricity is mostly transported by cables which run underneath footpaths.
At Northern Ireland Electricity Networks (NIE Networks), we have specialised teams of linespeople who work on both the overhead network and jointers who work on the underground network.
