Thermal Settings

Shield / CN (ICEA P-45-482)

T1 Shield Operating (deg C)

Typ. 80 — shield runs below conductor

T2 Shield Max (deg C)

350 thermoset / 200 thermoplastic

Conductor (ICEA P-32-382)

T1 Conductor (deg C)

105 = MV-105 (use 90 for MV-90)

T2 Conductor Max (deg C)

Insulation limit: 250 thermoset / 150 thermoplastic

Defaults suit typical MV-105 XLPE/EPR cable — rarely need changing.

Configure cable, enter fault parameters, and evaluate conductor and CN withstand per ICEA methodology.
