Experiments on Heating Uninsulated Wires of Overhead Transmission Lines

  • Published:
Power Technology and Engineering Aims and scope

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 theory of heat exchange, as well as generalized data on heating of wires and pipes obtained by various authors in different countries at various times, it is possible to suggest universal recommendations on determining heat exchange, and consequently also temperatures of round, stranded, and shaped wires for both longitudinal and transverse air flow by both weak and strong winds.
