CURRENT RATING
"Current rating (A) at an ambient temperature of 45°C
according to the standard IEC 60092-352
0,6/1 kV +90°C marine cables."

For continuous service. Continuous service for a cable is
to be considered as a current-carrying service (with
constant load) having a duration longer than three times
the thermal time constant of the cable, i.e. longer than
the critical duration(see short time duty).

Correction factor for intermittent service
according to the standard IEC 60092-352
The correction factor given hereby has been
roughly calculated for periods of 10 min,
of which 4 min are with a constant load and
6 min without load.
Intermittence period = 10min.
Intermittence ratio = 40%.
