UTILIZATION OF COMPOSITE INSULATORS FOR COMPACTING TRANSMISSION LINES

, , and .
(1991)

Abstract

Transmission corridor capacity can be increased by compacting transmission lines. Compaction is achieved by reduction of tower heights, spacing between conductors and tower and spacing between conductor bundles. These shorter spacings require the restraint of conductors. Composite insulators are ideally suited for maintaining conductor clearances because of their light weight and high strength. This paper analyzes both electrical and mechanical requirements for comyosite insulators to be used on compact transmission lines. Questions relating to life expectancy and aging in this application are raised and discussed. The results provide guidance for the design of compact lines with composite insulators.
