Such information includes properties of conductors and useful methods of calculation. The following chapters are included in this document.<br \/>\n\u2013 current carrying capacity of conductors: Calculation method and typical example<br \/>\n\u2013 alternating current resistance, inductive and capacitive reactances<br \/>\n\u2013 elongation of conductors: Thermal and stress-strain data<br \/>\n\u2013 conductor creep<br \/>\n\u2013 loss of strength of aluminium wires due to high temperatures<br \/>\nIt 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.<strong> <\/strong><br \/>\nThis second edition cancels and replaces the first edition published in 1995.
