Kapton wire concerns for aerospace vehicles

Abstract

This presentation outlines the background to the concern of using Kapton wire for aerospace vehicles and proposes it should not be utilized in new builds for spacecraft power applications. A NASA HQ investigation concluded that the risk of Kapton arc-tracking/flashover is a credible threat to the shuttle orbiter, but rationale is presented for continued flight for the time being. Recommendations for the protection of the shuttle and the build of the space station are given.
