ElecLink is a HVDC electrical interconnector under construction between the UK and France, passing through the Channel Tunnel.

The Challenge

The ElecLink project provides a power interconnector through the channel tunnel with a capacity of 1000MW between the UK and France, to provide cost effective generating capacity with low environmental impact and carbon reduction of circa 6.1 million tonnes. ​Working for Siemens Vysiion were requested to provide full security packages including CCTV, Access control and intruder detection systems.​ An additional challenge to this project was to integrate the systems with the existing Eurotunnel infrastructure.​


Vysiion provided active and passive infrastructure, real-time physical monitoring with CCTV, access control, perimeter intrusion detection systems, and security lighting.

Due to the nature of the site, the systems were fully redundant, including a 12-hour UPS. ​Full integration of all systems was completed, providing the user with a single interface for management of threats as well as integration into Eurotunnel’s management systems​.


    We have supplied all of the systems required and in turn upgraded the Eurotunnel management system so that it is able to integrate into the MISS system.​
    A secondary result from this engagement was that Vysiion was able to be seen by the operational telecoms team and this, in part, led to a further opportunity directly with Eurotunnel and another with ElecLink.​

    Key Deliverables

    • Active Network infrastructure​.
    • Passive network Infrastructure including CAT6a and Fibre.​
    • Security Panels.
    • UPS and associated power cabling .
    • Closed Circuit TV (CCTV) with recording​.
    • Intercom – main gate only (interface to Eurotunnel PABX is at MISS UK)​.
    • Access Control System (ACS)​.
    • Perimeter Intruder Detection System (PIDS) – fenceline, including gates​.
    • Interface with Building Intruder System (IDS)​.
    • Security Lighting – at both gates​.
