Transport Infrastructure

EL KONTROL executes projects in the field of transport infrastructure.

For the railway transport we have completed design and installation of a SCADA system for 8 railway stations, three main section stations and two traction substations along the railway line Sofia-Kalotina. The SCADA system installed in the 110/27 kV traction substation Voluyak allows automation control and monitoring from the substation but also remotely, from the Dispatch Center in Sofia.

Another project for the railway infrastructure is the rehabilitation of traction substations (TS) along the railway line Plovdiv-Burgas. We have completed overall rehabilitation of 110 kV and 25 kV switchgear and replacement of overhead power lines between the substations and the overhead contact system.

For the urban transport infrastructure we have carried out repair and rehabilitation of rectifying stations (RS) – as part of the trolleybus overhead contact system in Stara Zagora, Bulgaria, including elaboration of a Detailed Design.
