ABB ACS880-07 - Typical Power Cable Sizes

Typical power cable sizes
The tables below give the current carrying capacity ( I
Lmax
) and typical size for copper
and aluminum cables with PVC or XLPE insulation. A correction factor K = 0.70 is used.
Time const. is the temperature time constant of the cable.
The cable sizing is based on a maximum of 9 cables installed side by side on a ladder
type cable tray, with three trays on top of each other (with 30 cm of space between
the trays), and an ambient temperature of 30 °C (IEC 60364-5-52).
