France – Electrical wiring work – Travaux de relevé de câbles et de curage pour BT et CFA de toute la salle d’échanges de Gare de Lyon.

The subject of the contract is part of the redevelopment of the Gare de Lyon, which is part of the Renewal of Stations (RNG) project. The work aims to carry out a detailed and exhaustive inventory of the networks relevant to the disciplines of High Voltage (HV) and Low Voltage (LV), in the areas defined on the Gare de Lyon map. This is the case for the cables running along the ceiling but also for the networks running along the floor. The services planned are as follows, including the following types of cables: Cable survey work over an area of approximately 12,000m². Work to clear the area with an estimated 11,700ml. The types of cable concerned are as follows: Low voltage alternating current electricity (lighting, power, small power drive, supply to shops). Low voltage direct current electricity (electric traction). Low voltage (very low voltage electricity, communication networks, sound systems, SSI…). VDI network (data, voice, image) and optical fibres. Sound system. Video protection. Train line visualisation cameras (platform). Intercom and telephony. Passenger information. Access control. Toll (control lines and vending machines). Technical rooms. Control of escalators and lifts. SSI. GSM network. TETRA network. Railway transport systems (signalling, automatic control…).
