Project Details
This guide describes the effects and impacts of elevated temperature operation on conductors, connectors, and accessories. The guide identifies operating metrics which constitute elevated temperature operation based on present industry practices and its effects on overhead line components, and suggest potential mitigation options to manage and/or avoid identified adverse impacts.

Possible adverse impacts to an operating overhead transmission line which might occur when operating the line at high temperatures are discussed. Specifically, the transmission line?s conductor, connectors, and attached accessories in terms of degradation in mechanical properties due to annealing elastic and in-elastic elongation, and accelerated aging are explored along with limited mitigation recommendations. Additionally, predictor equations for accelerated creep and conductor loss of strength are detailed in annexes with limited example calculations.
