Case Studies Home > West Side Comp House 132kV Switchgear & cabling.
The Project was to install and lay a triple 132kV circuit between Bradford West GSP Substation and Bradford SP substation with the exception of one of the circuits which connected to tower PLK/05 close the Bradford SP Substation. The full route covered a distance of 10.1km. The works were required due to the age of the existing oil filled cables which had begun to degrade, causing leaks within the oil system. Modifications were completed to the primary substation GIS switchgear to allow uprated 132kV terminations, completed by Excalon.
The initial phase of the Works required site investigation to enable the design verification of the outline client design. Trial holes were undertaken at proposed joint bay locations and at areas of specific engineering difficulties.
The route had various challenges including works to cross a major culvert which required a specialised design to cross whilst protecting the 132kV cables, a Network Rail Bridge which required another specialised design provided by Northern Powergrid to install cable trays underneath the road deck whilst keeping a safe distance from the Overhead Lines for the railway. Significant inhouse traffic management was required along the full route which runs through the city centre of Bradford, due diligence was required to navigate Canal Road which is one of the main roads within Bradford and crossing major traffic sensitive junctions.
The complexity of the route required a full time customer liaison officer who provided continuous communication with a number of Stakeholders, including the Local Council, Network Rail for the bridge crossing, Yorkshire Water, Northern Gas Networks for crossing their assets, Several local schools, two local parish councils and all residents in the area, causing minimal disruption to all parties.
The duct installation was completed utilising Excalon’s in house excavation teams supported with specialists to undertake elements of the Works.
