Short Circuit Current Ratings

The short circuit currents quoted here are for IEC60092 STANDARD Offshore & Marine cables operating normally at maximum conductor temperature of 90℃.
XLPE insulation is actually capable of withstanding short-term temperature up to 250℃.
According to ICEA P-32-382 Curves based on formula:

IEC60092 STANDARD MariLan Marine Lan Data & Communication Cables

I: Short circuit current (kA)
A: Conductor area (mm² )
T1: Operating temperature (85℃)
T2: Short circuit temperature (250℃)
t: Short circuit duration (sec)

T1 = 90, T2 = 250
