This report describes reliability analysis of safety core insulators. Known incidents (Navy and non-Navy installations) of safety core insulator failure since 1970 were identified and categorized, and mean time between failure estimated. In general, safety core insulators were determined to be extremely reliable. However, it was found that reliability at one Navy installation (Cutler, ME) was poor due to the different configuration of the Cutler antenna and insulator, combined with the occurrence of large lightning strikes in that area. The report analyzes the failures at Cutler and provides recommendations to mitigate these failures. / NOTE: Technical rept. / Supplementary Notes: This is the work of the United States Government and therefore is not copyrighted.
