To improve transport links in the Vauxhall, Nine Elms and Battersea areas, we designed and delivered cabling works to power a new railway which is part of the Northern Line Extension scheme. Our works included a new 22kV cable circuit from the existing London Underground network to feed two substations, two transformer rooms and power the station and track for the extension.
Our expert team were responsible for the design, construction and commissioning of:
- A new 22kV cable ring circuit from the intake at Stockwell
- Two new traction direct current (DC) substations
- Two new low voltage transformer rooms
- 130 station switchboards, manufactured in-house at our Glasgow factory
The DC works involved the installation of:
- Track supply isolation switches
- DC traction feeder cabling from both substations
- Tunnel lighting supplies
- Track jumper cabling and gap equipment
Offsite efficiency
We worked collaboratively with London Underground’s team to develop all conceptual designs utilising our own in-house design team. This approach increased efficiency by reducing approval times.
Value engineering
To improve efficiencies, reduce costs and time spent on site, low voltage switchboards were designed and engineered by our expert team in Glasgow. The specialist designs were developed to ensure a seamless fit to the infrastructure. Find out more about our Switchgear Manufacturing capability.
Proven supply chain partner
Key milestones were completed ahead of programme by working collaboratively with our proven specialist subcontractor to deliver all aspects of high voltage, direct current and low voltage protection systems and commissioning.
