OVERVIEW

IUS completed the electrical construction works associated with the Lochend Wind Farm development. The connection of four 2.3MW Wind Turbines to the grid required a 33kV extension to the Scottish and Southern Energy electrical network. IUS was appointed to undertake the design and installation of the 33kV contestable elements of the connection activity.

DESCRIPTION

The project involved the supply and installation of a specialised multi-part GRP enclosure, which reduced construction costs and on-site installation times. Within the GRP housing, 33kV Schneider Electric WS switchgear was installed with connections made to the extra high voltage cable circuits using Pfisterer terminations. The design, installation, and commissioning of all associated DC and control systems also formed part of the IUS work scope.
