Electric Cables - Calculation of the Current Rating - Part 3-1: Sections on Operating Conditions - Reference Operating Conditions and Selection of Cable Type - Edition 1.1 Consolidated Reprint
N 60287-3-1
Annotation
This section of IEC 60287-3 is 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, 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.
This section concerns reference operating conditions and selection of cable type.

Электрические кабели - вычисление текущей оценки - часть 3-1: секции на условиях эксплуатации - справочных условиях эксплуатации и выборе типа кабеля - издание 1.1 объединенная перепечатка
Этот раздел IEC 60287-3 применим к условиям установившейся работы кабелей во всех переменных напряжениях и постоянным напряжениям до 5 кВ, проложенных под землей непосредственно в основании, в каналах, углублениях или в стальных трубах, и с и без частичного иссякания почвы, а также кабелей в воздухе. Термин “устойчивое состояние” предназначается, чтобы означать непрерывный постоянный ток (100%-й коэффициент загрузки) просто достаточный производить асимптотически максимальную проводниковую температуру, окружающие условия окружающей среды, принимаемые постоянный.
