Zaun’s RDS Protects Huge London Energy Upgrade Works

A rapidly-deployable temporary fence line has helped a construction giant deliver a key installation for National Grid to help meet London’s increasing energy needs.

A new 400kV Gas Insulated Switchgear electricity substation has been constructed as part of the EAN Framework and connected to a £1bn 32km electricity superhighway deep below the capital.

Chamber Platinum member Zaun Ltd provided 155 metres of high-security Rapid Deployable System (RDS) fencing for temporary protection of the construction works.  Zaun subsidiary Binns Fencing installed the system.

RDS has won a number of security innovation awards, has been used to secure the main political parties’ autumn conferences over recent years and forms part of the National Barrier Asset.

Three massive electricity transformers, each of which had to be delivered on a special 60m long trailer with a police escort, have been craned into place at the Seven Sisters Road substation.

The new 32km electricity superhighway is part of a seven-year £1bn project – due to be fully operational this year – to help keep Londoners connected to safe and reliable electricity supplies.

This involves reinforcing the high voltage network across London by installing new cables and wires in deep underground tunnels, from Hackney to St Johns Wood, Willesden to St Johns Wood and Wimbledon to Kensal Green.

The project includes the longest single-length cable pull in an underground utility tunnel in the UK.
