The phrase perfectly encapsulates the high-stakes physics of power transmission. The "hot crack" is the monster under the bed—the physical breakdown of materials under extreme thermal stress that leads to billions in infrastructure losses worldwide. But CYMCAP is the flashlight.

The most common culprit is an unrealistic thermal resistivity. cymcap hot crack

In extreme cases, installing water-cooling pipes alongside the power cables, modeled within the CYMCAP environment. The phrase perfectly encapsulates the high-stakes physics of

💡 If you have enabled the "Two-Layer Soil" or "Dry Zone" model, CYMCAP simulates a radius around the cable where moisture has evaporated. Once the soil dries, its Rho value jumps significantly. If the cable is already near its limit, this jump causes a "crack" where the temperature climbs to infinity in the simulation. The most common culprit is an unrealistic thermal

: Trapped heat scales rapidly. The localized temperature spikes well beyond the cable’s maximum design limit (typically 90°C for XLPE insulation). This creates a structural and thermal "crack" in the system's safety margin, leading to insulation melting, dielectric breakdown, and catastrophic phase-to-ground faults. 2.
