Scope

This part of JB/T 10181 specifies the basic operating conditions and cable selection related to the operating conditions. This section applies to the steady-state operating conditions of all AC voltage and DC voltage cables of 5 kV 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" refers to a continuous constant current (100% load factor) that is just sufficient to asymptotically reach the maximum conductor temperature under constant ambient conditions. This section contains baseline operating conditions and cable selection.
