Overhead electrical conductors. Calculation methods for stranded bare conductors
This document, which is a Technical Report, provides information with regard to conductors specified in IEC 61089 and other aluminium and aluminium steel conductors. Such information includes properties of conductors and useful methods of calculation.
The following chapters are included in this document:
Current carrying capacity of conductors: Calculation method and typical example
Alternating current resistance, inductive and capacitive reactances
Elongation of conductors: Thermal and stress-strain data
Conductor creep
Loss of strength of aluminium wires due to high temperatures
It is noted that this document does not discuss all theories and available methods for calculating conductor properties, but provides users with simple methods that provide acceptable accuracies.
