Electricity distribution and control apparatus

Tender description

Iarnród Eireann -Irish Rail's ‘IE’ Dublin area Rapid transit ‘DART’ network is a 1,500Vdc overhead line catenary system with traction return path through the track (running rails). It comprises some 45 kms of double track, 10 kms of single track and necessary stabling sidings in the Dublin area. The total length of contact wire is approximately 130 kms. The power for the Dart is supplied via 13 substations and 7 switch houses (also known as track paralleling huts or TPHs). IE requires the services of a competent company to design, supply, install, commission and train IE staff in the operation of a centrally controlled independent emergency shut down facility for 20 traction substations/ TPHs on the Dart electrified network. This shutdown network once established would possibly become the standard for all future projects so it is vital that this system is capable of expanding to cater for additional locations. Independent emergency shutdown system for traction power.
