Guidelines for electrical transmission line structural loading
Book

OSTI ID:6959429
Prevailing practice and most state laws require that transmission lines be designed, as a minimum, to meet the requirements of past or current editions of the National Electrical Safety Code (NESC 1990). The NESC is primarily intended to cover electrical features of a transmission line. Its current set of rules for the selection of loads and overload capacity factors does not have a consistent basis. Some designers feel that the NESC rules are too restrictive, while others adopt design criteria well above the NESC minimums. Based on responses to a transmission line loading questionnaire (ASCE 1982), utility design procedures show considerably more variation among themselves than could be attributed to variability in environmental load conditions. This paper reports that for this reason, the ASCE Committee on Electrical Transmission Structures has devoted a substantial effort to develop reliability-based design guidelines for transmission line structural loadings.
