Scope

This standard applies to the steady-state operating conditions of all AC voltage levels and DC voltage cables of 5kV and below laid in the air or soil. The soil includes cables laid directly buried in the ground, pipes, cable trenches or steel pipes with or without local soil drying. The term "steady state" means that a continuous constant current (100% load factor) is just sufficient to asymptotically reach the maximum temperature of the conductor under assumed constant ambient conditions. This section covers baseline operating conditions and cable styling.
