Case Study – Beauly – 132kV Power Cable Circuits
Nexus Power Ltd was contracted by J Murphy & Sons to prepare and install 24 No. Prysmian Outdoor Cable Sealing Ends at Beauly Substation, Inverness. The project consists of an extension and reinforcement to the existing Beauly Substation, as part of the main Beauly to Denny double circuit 400kV overhead line project. This project requires the rationalisation and diversion works including replacement of sections of 132kV, 33kV and11kV lines with underground cables at various locations.
The 132kV power cable was 630mm2 Al conductor with a lead sheath. The terminations were composite design incorporating a welded conductor connection. The jointing and specialist welding techniques was completed by our own team of skilled joiners who are approved and certified to joint cables up to 275kV.
