Overhead electrical equipment

Tender description

Network Rail requires Tensioning Devices, operated via coiled spring(s), to maintain mechanical tension in the overhead contact line conductor(s) for use on 25kV AC or 25-0-25kV AC Electrified Lines. The A.C. electrification traction supply system forms part of the railway infrastructure owned and operated by Network Rail. The system consists of feeder stations, track sectioning sites, a 25 kV (classic) or 25 kV / 0 / 25 kV (autotransformer) overhead line contact system and associated SCADA systems. Tensioning Devices shall be designed to attach to the structures provided for support of the overhead contact line system, either on masts located adjacent to the track (single track cantilever structures / 2 track design). Network Rail is seeking to understand what options exist that meet its requirements. Network Rail wishes to engage with suppliers who have a product that either meets all these requirements, or could meet them with minimal adaptation. Further details will be released at the end of the PIN validity period. Interested suppliers should email gavin.truslove@networkrail.co.uk no later than 13:00 on 9.11.2017. Please reference your interest as ‘PIN Tensioning Devices’. The output of this engagement will determine tender scope and time-scales.
