In the engineering world, (developed by CYME International T&D) is the industry standard for power cable analysis. While the "Hot Crack" is an instrument accessory, CYMCAP software handles the mathematical equivalent of thermal limits:
refers to the severe structural failure and cracking of power cable insulation caused by localized thermal hotspots, a risk that power engineers systematically mitigate using Eaton's CYMCAP Power Cable Ampacity Software . When underground high-voltage cables operate under high loads, they generate substantial heat. If this heat cannot dissipate efficiently into the surrounding soil, the temperature spikes at specific "hotspots". Over time, this localized thermal stress causes cross-linked polyethylene (XLPE) or paper-insulated lead-covered (PILC) insulation to become brittle, degrade, and crack. These "hot cracks" breach the dielectric material, triggering catastrophic electrical faults, short circuits, and localized system grid outages. The Physics of a Hot Crack cymcap hot crack

This paper systematically characterizes the hot cracking phenomenon, identifies root causes, and proposes alloy modifications and process controls. If this heat cannot dissipate efficiently into the
Engineers use the CYMCAP calculation engine to perform high-stakes thermal analysis. Key functions include:
