Mitigating Thermal Risks: Understanding Hot Spots with CYMCAP
(joule) losses in the conductor, dielectric losses in the insulation, and induced circulating currents in the metallic shields or sheaths. Under normal conditions, this heat conducts outward through the cable components and dissipates into the surrounding soil. A hot spot occurs when this thermal equilibrium is disrupted by specific environmental or physical factors: 1. Soil Thermal Dehydration (Thermal Runaway) cymcap hot crack
A hot crack is the final physical manifestation of prolonged thermal-mechanical stress on cable insulation.
: Move beyond steady-state. Model how cables react to peak loads over time to ensure they don't hit "hot" thresholds during emergency cycles. Duct Bank Optimization Are you working with or direct buried cables
This heat dries out the surrounding backfill or soil.
Understanding and Preventing Cable Trench "Hot Cracks" (Thermal Dry-Out) Using CYMCAP Under normal conditions, this heat conducts outward through
Copper and copper-clad steel conductors become significantly softer as they approach their melting point (approx. 1085°C). However, during the rapid heating of a fault, thermal expansion generates immense mechanical stress. If the conductor is rigidly clamped or restricted, the stress cannot be relieved by movement. This can cause the material to tear or crack, particularly at points of geometric stress (bends) or connection points.
