Overload capability of power cables in actual
power consumption systems.
Results of overload capability calculations for 6-kV power cables are analyzed. The work is aimed at creating a computation
system for the current rating of high-voltage cross-linked polyethylene power cables.
Key words – overload capability, power cables, cross-linked
polyethylene insulation.
