Powertek worked in conjunction with Integrated Utility Services to undertake the installation of the 11kV electrical infrastructure for the Scottish Water Gorbals Pumping Station.

The power for the three 1.2MW pumps required a 3.6MVA connection from the Scottish Power Energy Networks existing 11kV system.

This required Powertek to excavate, install and reinstate a 12km 95-300mm² 11kV cable run and undertake all jointing works including 44 HV Straight joints, 4 HV Trifurcating Joints and all associated indoor HV terminations.

The Civil Works involved: excavating and reinstating 12km of track along busy, type 3/4 carriageway; through a major 4-way roundabout; under three railway bridges and over numerous road bridges – some of which required additional engineering solutions to negotiate.

In order to overcome these challenges, nightshift teams were utilized when required, professional traffic management teams were used throughout the entirety of the 12km excavation and a temporary on-site compound was created.

Certain road bridges required steel duct crossings where dia holes were cored into abutment walls in order to install dia steel pipes containing plastic duct. This allowed for the HV cable to pass through the bridge in a safe and time-effective manner that also helped to retain the aesthetics of the area once the works had finished.

All works were completed within client specifications and budget.
