Douglas North Onshore Project
Turnkey project included the design, manufacturing and supply of 10 km of 132 kV XLPE-insulated cables and associated accessories, installation & final testing services.
SP Transmission PLC (“SPT”) is one of UK’s largest grid operators. The existing Coalburn to Middlemuir 132kV underground cable circuit was required to be modified in order to facilitate the connection of 2 new wind farms; Douglas West (51 MW) and Kennoxhead Extension (60 MW).
