Within tunnels, 400V supplies are required to feed heavy plant, conveyors, compressors, pumps, fans, etc. Due to the nature of the operations, a lot of equipment needs to be plug-in or extendable, so that it can move forward with the work face.
A wide variety of LV electrical distribution equipment can be required on a tunnel project. Main LV supplies into tunnels are often provided with a back-up stand-by generator and our Mains Distribution Assemblies (MDAs) can incorporate Manual or Automatic Changeover systems to switch between Mains and Stand-by power.
Power supply and distribution in a tunnel Tunnels are home to a variety of applications that need to be supplied with power in a high-availability configuration. Particularly critical subsections, such as ventilation and lighting, must continue to work even in emergency situations, for example during severe fires.
below are some typical tunnel distribution schemes at 400V, 1000V and 3300V. 400V Distribution When tunnel distribution is carried out at 400V, Cable Link Boxes can be provided which will typically accept incoming and outgoing SWA cables with a cross section of 95mm2 4C and switchgear rated up to 250A.
