Flame and radiation resistant cable
Abstract
Abstract A flame retardant, radiation resistant insulated conductor, either in single conductor form or having a plurality of insulated conductor assemblies each comprised of an electrical conductor core, a flexible flame-resistant barrier layer of an inorganic electrical insulating material which surrounds the core, an electrical insulating layer of a polymer material which surrounds the barrier layer, a second flame retardant barrier layer of an inorganic electrical insulating material which surrounds the polymer insulating layer, and a second electrical insulating layer of a halogen containing polymer which surrounds the second barrier layer and jackets the insulated conductor. The plurality of insulated conductors are wrapped together, preferably twisted together, within a flame retardant barrier shell of an inorganic electrical insulating material. The shell is jacketed with a flexible flame retardant, electrical insulator covering of a halogen containing polymer.
