Tunnel Inelfe, SPAIN – Lighting – Work phase
Tunnel lighting from 0 to 5000 meters
Lighting power supply - 200 Fluo 56 W lamps and two 20 kW pumps from the tunnel construction phase.
The installation will be installed in an existing substation. The 950 V solution does not power the lighting and the pumps.
Altitude less than 1000m and maximum temperature of 55°C
Our solutions implemented
The 400 V three-phase low-voltage step-up transformer substation transforms this voltage into 3.2 kV three-phase.
From the transformer station, a tripolar cable feeder, specified 66 kV
with copper conductor of 3x25 mm2 of section feeds a 25 kVA step-down transformer and a 80 kVA transformer type TER 3200 V / 400 V + N
- Using a permanently powered network, the lighting will always be switched on
One step--down transformer 80 kVA TER 3200 V / 400 V + N type
