This section includes technical information and details about the cables we manufacture. The information can be utilized e.g. design, sourcing and resale operations.
Thermal short-circuit current for power cables 0,6/1 kV
Tabulated short circuit currents are calculated for one second duration. For duration 0,2 – 5 s short-circuit currents can be calculated from formula below.
I short-circuit = I1s / t1/2
t = short-circuit duration in seconds
I1s = 1 second short-circuit current

– XCMK-HF, FRHF-EMC
– AMCMK, AEMCMK
