Typical power cable sizes
The tables below give current carrying capacity ( I
Lmax
) for aluminum and copper PVC/XLPE
insulated cables. A correction factor K = 0.70 is used. Time const is the temperature time
constant of the cable.
The cable sizing is based on max. 9 cables laid on the cable trays side by side, three ladder
type trays one on top of the other, ambient temperature 30 °C (EN 60204-1 and
IEC 60364-5-52).
XLPE insulation
Conductor temperature 90°
PVC insulation
