Description
IEC 60287-2-3:2017 describes a method for calculating the continuous current rating factor for cables of all voltages installed in ventilated tunnels. The method is applicable to any type of cable.
The method applies to natural as well as forced ventilation.
Longitudinal heat transfer within the cables and the surroundings of the tunnel is assumed to be negligible.
All cables are assumed to be identical within the tunnel and it is assumed that the tunnel cross-section does not change with distance along the tunnel.
