Abstract:

The paper is concerned primarily with the sheath construction used in terminating cable. This application, therefore, requires a cable specifically designed to meet certain needs. Considering where and how it is used, it must Have a fire resistant outer jacket since it is installed inside buildings. Withstand the flexing and sharp radius bends so often necessary with installations in limited access areas. It was decided that the standard 8-mil thick aluminum used for years in Alpeth sheath provided adequate shielding. The next step was to find a plastic material with electrical characteristics and low temperature brittleness properties approaching those of polyethylene. A polyvinylchloride sheathing compound with adequate electricals and low temperature brittleness which could tolerate bending and handling at -30F. was formulated. After passing all tests, it was finally accepted and the material described in a formal material specification. The resulting sheath construction was designated Alvyn. Author
