The purpose of this guide is to provide general recommendations for consideration when designing new overhead transmission lines that will be operated at high temperatures. It may also evaluate existing transmission lines for operation at higher temperatures. Although this guide is intended for overhead transmission lines, most of the discussion will also be applicable to distribution lines.

Prepare an IEEE guide describing the effects of high temperature operation on conductors, connectors, and conductor hardware. The guide will no only identify what constitutes elevated temperature operation and its effects on the above overhead line components, but will also suggest some mitigation techniques for consideration.

Provide guidance to utilities when investigating the impacts of elevated temperature operation on their transmission facilities. Such guidance can assist in avoiding or mitigating described adverse thermal effects.
