IEC 60287-2-1:2023
Electric cables - Calculation of the current rating - Part 2-1: Thermal resistance - Calculation of thermal resistance
OVERVIEW
IEC 60287-2-1:2023 is solely applicable to the conditions of steady-state operation of cables at all alternating voltages, and direct voltages up to 5 kV, buried directly in the ground, in ducts, in troughs or in steel pipes, both with and without partial drying-out of the soil, as well as cables in air. The term "steady state" is intended to mean a continuous constant current (100 % load factor) just sufficient to produce asymptotically the maximum conductor temperature, the surrounding ambient conditions being assumed constant.
