These criteria apply to work on a specific ship or ships only when invoked by the Ship Specifications or similar contractual documents. 4. These criteria are for application to new construction, conversion, and alteration of ex

4、isting ships. 5. Considering the magnitude of this standard, along with the changing requirements imposed on the Electric Plant, it is inevitable that changes will be required to update these criteria. Therefore, as comments arise, they should be forwarded to Naval Sea Systems Command (NAVSEA) 05Z3

5、to keep this standard as current as possible through subsequent revisions. Revisions will be accomplished by the issuance of additional or revised figures to be inserted in the basic standard parts. Superseded pages may be retained for reference if so desired. 6.

This standard covers standard methods for cable preparation and end-sealing, entry to equipment and connectors, repair and splicing. 1.1.1 Application. These installation methods are to

14、 be used by all installing activities. These methods do not identify ship or type but do establish minimum standards of acceptance for Naval ships. It is the responsibility of the user activity to determine which method satisfies their requirements. It does not authorize relaxation of any requiremen

15、t specifically invoked by new construction, conversion, overhaul, or refurbishment contracts. In instances where deviated design requirements (for example, ship type, ship class, and so forth) conflict with the requirements of this standard, the requirements of this standard govern. Any deviation fo

16、r electric plant installation identified in this standard is to be submitted to NAVSEA 05Z3 for resolution. 1.1.2 New cable specifications. Refer to the cable comparison handbook (MIL-HDBK-299) for guidance in substituting MIL-DTL-24643 cable for equivalent MIL-DTL-915 cable applications. All cable

17、type designations specified herein, to be in accordance with MIL-DTL-24643, are preceded by the prefix “LS”. The following cable types are in accordance with MIL-DTL-915 for use as outboard or portable applications and have no MIL-DTL-24643 equivalent: DLT TRF MSPW 3PR-16 DSWS TRXF MSP 1Q-16 DSS TSP

Provided by IHSNot for Resale-,-,-MIL-STD-2003-1A(SH) 3 3. DEFINITIONS 3.1 Cable repair. Cable repair refers to restoration of only the cable ar

32、mor or the outermost cable sheath or both. 3.2 Flooding water level II (FWL-II). FWL-II is the highest water level that can be expected above the bulkhead deck at any particular intact watertight subdivision after any flooding elsewhere in the ship which the ship is expected to be capable of survivi

33、ng. If FWL-II is unknown, consider the main deck to be the FWL. 4. GENERAL REQUIREMENTS 4.1 Cable. 4.1.1 Cable slack. Where cables enter electrical equipment, a minimum of two inches of slack cable shall be provided in the cableway, permitting repairs to be made at the cable ends, avoiding cable rep

34、lacement. Cable conductors shall also have two inches of slack inside the enclosure. 4.1.2 Supporting cables entering enclosures. Cables entering enclosures shall be secured to bulkheads and shall not exceed the cable bend radius. 4.1.3 Cable bend radius. Cable bend radius shall be in accordance wit

35、h MIL-STD-2003-4. 4.1.4 Box connectors, electrical. Junction box or outlet connectors shall be in accordance with A-A-50552 type, class, and style listed or other connector as approved by NAVSEA. a. Straight connector for single round cable Type 1, Class 1, Style A. b. Straight connector for duplex

36、round cable Type 1, Class 1, Style B. c. 45-degree angle connector for single round cable Type 1, Class 1, Style C. d. 90-degree angle connector for single round cable Type 1, Class 1, Style D. 4.1.5 Cable connection. Changes in conductor size other than at switchboards or panels shall be made by us

37、e of electrical enclosures, terminal boxes, or other equipment specified herein or on standard drawings. At the point of connection, the separation of conductors and the removal of sheathing shall be in accordance with the requirements specified herein and shall be kept to a minimum. On parallel cab

38、le runs, the length of sheath removed from each cable shall be equal. 4.1.6 Watertight cables. Cables terminating at the following equipment, located below FWL-II (see 3.2), shall be watertight. There are two acceptable methods for watertight cables: water blocked and end-sealing. a. Power and light

39、ing switchboards (includes ship service, emergency and load center switchboards). b. Manual and automatic bus transfer equipment (whether mounted on a switchboard or panel or as an independent unit). c. Distribution power and lighting panels supplied from two sources of power. d. Degaussing switchbo

40、ards, control panels, and power supplies except where they supply power to only one degaussing coil. e. Watertight interior communication and weapons control equipment, including switchboards, control panel, and connection boxes, where water seepage into the unit would jeopardize undamaged operable

41、portions of the system. f. Top entrance cable to interior communication and weapons control switchboards of other than watertight construction. g. In minesweepers only, degaussing. h. Degaussing connection and through boxes having connections for more than one degaussing coil. 4.1.6.1 Water blocked

42、cables. Water blocked cables shall be in accordance with MIL-DTL-24640 or MIL-DTL-24643. Water blocked cables are the preferred method and shall be used unless end-sealing is approved for use by NAVSEA. Provided by IHSNot for Resale-,-,-MIL-STD-2003-1A(SH) 4 4.1.6.2 Cable end-sealing. Although end-s

43、ealing is an acceptable method, it is usually less economical and therefore only used when approved by NAVSEA. 4.1.6.3 Watertight cable exceptions. Cables terminating at equipment designated need not be watertight where one or more of the following conditions apply: a. Flexible cables to rotating st

44、ructures. b. Cables which do not pass through a watertight deck or bulkhead. c. Cables which penetrate FWL-II but do not pass through a watertight deck or bulkhead below FWL-II (see 3.2). d. Where water seepage into a unit of an interior communication or weapons control system through a damaged cabl

45、e would result in no loss of function beyond that already sustained due to cable casualty. e. In interior communication systems, and weapons control systems, cable Types TTSU and MSCU, and all electronic, communication and instrumentation two, three, and four-conductor cable of size 9 and smaller. 4

46、.1.7 Cable lug terminals. Cable lug terminals shall be installed on each connected conductor unless cable is terminated by a connector. Lug terminals shall conform to MIL-T-16366 (solderless type), SAEAS7928/1 (insulated barrel solderless type), NASM 77072 (solder type), or NASM 77073 (solder type).

47、 4.1.7.1 Application. Solderless type lug terminals shall be used for all applications except for equipment having requirements for solder type terminals or in specified electrical enclosures in which electrical clearances would be reduced below minimum standards by the use of solderless types. 4.1.

48、8 Cable entrance to machinery and equipment. Cable entry into bulkhead-mounted non-watertight equipment shall be through the bottom or lower half of the side unless otherwise approved by NAVSEA. Cables shall enter watertight equipment in locations best suited to disposition of the cable installation

49、. Sufficient slack shall be allowed for cable connection to machinery to prevent damage to cables, due to vibration, at locations where the cables pass from the structure of the ship to the machinery. Cables connected to equipment provided with resilient mounts shall have a minimum length between the equipment and the last point of support of the cable of 18 inches with sufficient slack to provide for flexibility a
