This document supplements departmental manuals, directives, military standards, and so forth, and provides basic information on shipboard cables. It contains listings of shipboard cable
18、s, data tables, and supersession information, and should provide valuable facts and guidance to personnel responsible for the design, handling, installation, and maintenance of shipboard cable. 2. The “Cable Comparison Handbook“ was first published in 1946 to facilitate utilization of electrical shi
19、pboard cable, and to assis-t-in the planning of cable installations. A reprint was issued in 1948, and revised editions were printed in 1953, 1956, 1960, 1964, 1975, and 1977. This 1988 edition contains information on current cables. The information is based on current data, Section 304 of the Gener
20、al Specifications for Ships of the United States Navy, and MIL-C-915, MIL-C-24640, and MIL-C-24643. 3. For many years most of the shipboard power and lighting cables for fixed installation used silicone-glass insulation, polyvinyl chloride jacket, aluminum armor, and watertight construction. It was
21、determined that cables with all of these features were not necessary for many applications, especially for applications within watertight compartments and non-critical areas above the watertightness level. Therefore, for applications within watertight compartments and non-critical areas, a new famil
22、y of non-watertight lower cost cables was designed. This new family of cables is electrically and dimensionally interchangeable with silicone-glass insulated cables of equivalent sizes, and is covered by MIL-(3-915. Additionally, cables jacketed with polyvinyl chloride presented the dangers of toxic
23、 fumes and dense, impenetrable smoke when undergoing combustion. These hazards became increasingly evident when an electrical fire smoldered through the cable ways aboard the DDG 19 (USS TATTNALL). Because of the overwhelming amount of smoke and fumes, firefighters were unable to effectively control
24、 the fire, and a large amount of damage resulted. A new family of low smoke, low toxic cable, constructed with a polyolefin jacket vice polyvinyl chloride jacket, conforms to rigid toxic and smoke indexes and effectively reduces the hazards associated with the polyvinyl chloride jacketed cables. The
25、 new low smoke cable is covered by MIL-C-24643. A family of lightweight cables has also been introduced to aid in the elimination of excessive weight from the fleet. Considering the substantial amount of cable present on a ship or submarine, a reduction in cable weight will have a considerable impac
26、t on the overall load, thus improving performance and increasing efficiency. This new family of lightweight cables is constructed from cross-linked polyalkene and mica polyimide insulation, anda cross-linked polyolefin jacket, .The lightweight cable -is covered by MIL-C-24640. 4.- Cables are listed
27、in this handbook by general classification according to application and design.
