In the standard for contact wires made from copper and its alloys, the values of long-term permissible temperatures have significantly decreased. This requires recalculation of previously valid values of long-term permissible currents. Authors consid

It is shown that currently-accepted assumptions for calculating heat exchange for stranded and shaped wires of overhead lines are unsubstantiated and result in unjustified errors in the analysis of heating of wires. Using known provisions of the theo
