Abstract

See full text

A fire resistant corrugated coaxial cable is described that employs a high-temperature, insulating alkaline earth silicate (AES) wool dielectric. The AES wool dielectric is devoid of water as a constituent. The AES wool may be survivable under conditions of high heat, such as temperatures specified by common fire test standards (e.g., 1850° F./1010° C. for two hours). The cable is configured to maintain a relatively coaxial relation between a center conductor and an outer conductor even under aforementioned fire tests. A layer of ceramifiable silicone rubber or refractory fiber wrap can surround the outer conductor and continues to insulate it from the outside if a low-smoke zero-halogen (LSZH) jacket burns away.
