This is the conventional baseline calculation, assuming no heat is dissipated to the cable's surroundings. It provides a fundamental starting point for the calculation.
Assumes a fault happens so quickly (typically under 5 seconds) that zero heat transfers to the insulation. The conductor absorbs 100% of the thermal energy.

One of the most common applications is for the "thermal stability checking" of cables. When a fault occurs, especially in high-voltage systems, the fault current can flow through a cable's metallic screen or sheath. If the screen is undersized, it can overheat, damaging the main insulation and requiring a costly and complete cable replacement.
