Scope

This standard gives the performance and calculation methods of overhead conductors involved in GB/T 1179-2017 and NB/T 42060-2015, including: —— Conductor ampacity: calculation methods and typical examples; —— AC resistance, inductance - wire elongation: thermal and stress-strain data; - wire creep; - loss of aluminum wire strength due to high temperature; This standard does not contain all methods and theories for calculating the properties of conductors, but gives simple methods with a certain degree of accuracy. This standard applies to the relevant performance calculations of overhead conductors involved in GB/T 1179-2017 and NB/T 42060-2015.
