$$I_permissible = I_AD \times \epsilon$$
Calculate the (assuming no heat escapes the conductor).
: These often have better heat dissipation than the core conductor.
IEC 60949 outlines methods for calculating thermally permissible short-circuit currents in cables, featuring specific thermal constants for impregnated paper insulation. The standard provides formulas for determining current ratings based on material properties, including thermal resistivity and volumetric specific heat for paper-insulated components.
