Cable trenching is an essential part of wind farm projects. It serves to carry the cabling and communications equipment from the turbines to the substation, where the medium voltage electricity is increased in voltage with a transformer to connect to the electricity grid. On some wind farms it is also necessary to provide trenching (interconnector) to bring the higher voltage electricity to the grid.

"Wind Farms Civils" have experience of providing cable trenching in different ground conditions, crossing waterways and roads on various wind farms.
