Abstract
Electrical cables run fore and aft in tightly packed cable trays on all decks on a warship. During a fire the polymeric coverings on these cables present a high fire load and in addition the fire can progress rapidly throughout the ship along cable runs producing large amounts of fumes and toxic combustion products along the way. Further, many important shipboard systems can be rendered totally ineffective as a result of a loss of electrical power caused by shorting or melting of conductors. Consequently it would be extremely beneficial to have cables that had a high temperature performance capability which could remain operative even in a fire situation. It would be a further significant benefit if the sheathing on shipboard cables was non-combustible and did not release fumes and toxic gases when burned. This presentation will describe the development and testing of an inexpensive, lightweight, flexible ceramic electrical cable sheathing. Details of the materials' development and testing of cable segments for normal and high temperature (1000C) performance will be presented. The presentation will include a video taped summary of the testing of the cable under fire loading relative to a commercially available polymer sheathed cable. In addition a sample of prototype cable will be available for examination.
