If the simulation runs, the issue is likely the thermal interaction between cables. If it still fails, the issue is with the individual cable's construction or the immediate soil parameters. 4. Advanced Fixes
A wide freezing range (>150°C) is a known susceptibility factor for hot cracking, as it promotes extended coherent dendrite networks with residual liquid films at grain boundaries.
This article will explore the concept of "hot cracking" in physical materials, explain why it threatens cable longevity, and demonstrate how engineers use to predict, model, and mitigate these dangerous thermal stresses to ensure a resilient power grid.
CYMCAP is not a "cracking tool"; rather, it is a highly specialized analytical tool developed by Eaton (formerly CYME). Its primary mission is to calculate the of a power cable.
[High Load Current] ➔ [Localized Heat Trapped] ➔ [Insulation Degradation] ➔ [Thermal Micro-Cracking] ➔ [Dielectric Breakdown / Cable Failure] 1. Thermal Overheating
One of the most common locations for a physical and thermal "hot spot" is an intersection where two separate cable circuits cross each other.According to Eaton's CYMCAP 3D Modeling documentation , traditional 2D equations fail when cables are not parallel. The 3D module simulates the exact intersection point where mutual heating is compounded, ensuring that overlapping thermal fields do not cook the cables from the outside in.
