March 7, 2022 London Power Tunnels project – a special commission

FSP has completed a special commission to manufacture and supply cable towers and frames to a network of power tunnels underneath London for infrastructure specialists J.Murphy & Sons.

The highly valued contract saw us deliver two towers and frames that will feed cables to different heights inside the London Power Tunnels near Croydon. Both towers were supplied in sections for on-site assembly, one 6.5m tall and the second approximately 3.5m tall.

It is the latest in a series of contracts for the National Grid project that is investing £750m to upgrade and future proof the capital’s electricity supply. We have already supplied more than 1,500 cable brackets for the sub stations on the same contract.

It followed on from the stretcher access covers and duct cover systems we supplied for the first phase of the Power Tunnels project.

The towers and frames were manufactured to our customer’s specification and had to meet BS EN 1090 Execution Class 2 (Steel Structural Products).

Managing Director Richard Hilton said: “We are pleased to be continuing our association with this major infrastructure project.

“The towers provide the framework for the cables to cope with the changing heights within the tunnels. We were able to use in-house design capabilities and knowledge of this project to work with our client and deliver a bespoke product within the timeframe required, thanks to our flexible manufacturing schedules.”
