Acrastyle input helps power High Speed 1

The new high speed rail line between the Channel Tunnel and the newly refurbished St Pancras International terminal will commence commercial services from 14th November 2007. Acrastyle, a long and well respected supplier to power utilities, is right to feel proud of its involvement in such a prestigious project.

Acrastyle has a long and impressive track record in the design and manufacture power system protection and control equipment for utility companies both domestically and internationally. In addition, Acrastyle has also provided traction power protection and control panels and relay room enclosures to Network Rail at various sites across the UK including Birmingham Cross City electrification and Carstairs – Edinburgh electrification.

Acrastyle was excited to be involved in the 74km first construction phase of CTRL from the Channel Tunnel to Fawkham Junction near Gravesend. The company was selected by the main contractor, Balfour Beatty Rail Projects, to design and build the traction power system protection panels for the National Grid intake sites at Sellindge and Singlewell, as well as 12 autotransformer sites. In addition, Acrastyle was then also selected by the SVC supplier ABB to provide control panels at Singlewell substation site.

After the success of the first phase, Acrastyle was rewarded with even greater responsibility and scope for the second construction phase. The main contractor, ABB, selected Acrastyle to provide both traction power system protection panels and standby control panels for National Grid intake at Barking and at traction feeder stations at Choats Road, Stratford & St Pancras, as well as a further 4 autotransformer sites. Acrastyle was also responsible for providing the EDF monitoring and control system for the power system infrastructure. This is an integrated control and monitoring system which gathers and displays alarms, status indication, events, analogue values and fault/disturbance records locally at each site via fibre optic LAN. The system can be viewed, interrogated and operated locally at substation level and all information is transmitted, via secure VPN, to the overall EDF operations and maintenance control centre for High Speed 1 near Singlewell in Kent.

The protection and control systems deployed at each site utilise state of the art technology and was developed, configured and tested by Acrastyle to the bespoke requirements of the CTRL power system network.

Bill Rodger, Acrastyle managing director, says: “We are extremely proud to have been involved with the CTRL/High Speed 1 project during both phases. Acrastyle’s experience and knowledge of power system control and protection together with our deep understanding of the capabilities of equipment from a wide range of relay suppliers enabled the optimum solution to be offered, designed, manufactured and installed.”

Acrastyle UK was founded in 1962 on the edge of the Lake District. Today, with two manufacturing units in Ulverston and new facilities in Chennai, they are a leading independent supplier of protection. control and substation equipment worldwide. As part of the S&S Power group of companies, Acrastyle remains an authority on the protection and control of plant and power systems to utility, infrastructure, commercial and industrial clients the world over.
