2、permitted without license from IHS-,-,-MIL-STD-2003-4A(SH) ii FOREWORD 1. This standard is approved for use by the Naval Sea Systems Command, Department of the Navy, and is available for use by all Departments and Agencies of the Department of Defense. 2. This standard disseminates up-to-date inform

3、ation detailing requirements for standard installation methods employed for submarine and surface ship electrical distribution systems. 3. 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

4、 application to new construction, conversion, and alteration of existing 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, th

5、ey should be forwarded to Naval Sea Systems Command (NAVSEA) 05Z3 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 Superseded pages may be retained fo

6、r reference if so desired. 6. Comments, suggestions, or questions on this document should be addressed to Commander, Naval Sea Systems Command, ATTN: SEA 05M2, 1333 Isaac Hull Avenue, SE, Stop 5160, Washington Navy Yard DC 20376-5160 or emailed to CommandStandardsnavy.mil, with the subject line “Doc

Unless otherwise noted herein or in the contract, in the event of a conflict between the text of this document and the references cited herein, the text of this document ta

30、kes precedence. Nothing in this document, however, supersedes applicable laws and regulations unless a specific exemption has been obtained. 3. DEFINITIONS 3.1 Bottom loading. Cable secured to the underside of a cableway tier. 3.2 Cableway tier. Cableway tier is one row of cable installed in a cable

31、way. 3.3 Double banking. Double banking is two rows of cable installed in a single tier of a cableway. 3.4 Multiple banking. Multiple banking is three or more rows of control and/or instrumentation cables on a single tier or in a cable tray. 4. GENERAL REQUIREMENTS 4.1 Location of cable runs. Main f

32、ore-and-aft cableways shall be located port and starboard, high and low in ship; lower cableways shall be through machinery spaces and corresponding platform decks, upper cableways under the main deck. This is to provide a quadrangular pattern to allow maximum athwartship and vertical separation of

33、cables to loads requiring two sources of power for systems requiring alternate reliability circuits. For example, a ship service power feeder in the lower starboard cableway should have its complementary emergency or alternate feeder in the upper port cableway. 4.1.1 Vertical cable runs. Vertical ca

34、ble runs shall be organized on the basis of the fore-and-aft or athwartship separation. 4.1.2 Emergency diesel generator seawater booster pumps. Cables supplying emergency diesel generator seawater booster pumps shall be run in the same compartment with, and as close as practicable to, but shall not

35、 be attached to the water piping connecting the pump to the diesel engine. Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-STD-2003-4A(SH) 3 4.1.3 Interior communications and weapons control. The main runs of interior communications and weapons c

36、ontrol system cables shall follow cable runs of lighting and power installations. Interior communication and weapons control cables for circuits having several interrelated main and interrelated auxiliary circuits shall be run so that main circuits including normal power supply will be in one group

37、and auxiliary circuits including alternate power supply will be in another group. 4.1.4 Control from more than one location. Where equipment is controlled from more than one location, the control cabling from each location to the equipment shall be installed in separate wireways. 4.1.5 Weather expos

38、ure. Cables shall not be exposed to the weather except where they penetrate a deck or bulkhead to supply equipment. Cables exposed to the weather shall be kept to a minimum. Where possible, cables exposed to the weather shall be protected by installation within conduit, masts, staffs, macks, and yar

39、darms. 4.1.6 Circuit trunking. Location and arrangement of cable runs shall provide circuit trunking avoiding physical interferences with piping and ventilation ducts. Spaces considered harmful to cable or subject to explosion hazards shall be avoided. Cableways shall be arranged so that ventilation

40、 will be adequate for maintaining the minimum practicable temperature of cables within the cableway. Cableways shall be located so the cables will not be disturbed by disassembly or removal of machinery. 4.1.7 Armored cable. Armored cable has been identified as detrimental to the ability of low smok

41、e cable to self extinguish. As a result, armored cable is no longer permitted aboard Naval ships except where necessary to provide physical protection to certain cables. These applications are limited aboard ship. Armored cable shall not be installed in weather exposed areas unless run in conduit. T

42、he following armored cables are permitted aboard ships: a. MIL-DTL-24640/15, 2XSAWA b. MIL-DTL-24643/24, LSTCKX, LSTCTX, and LSTCJX c. MIL-DTL-24643/25, LSPI d. MIL-DTL-24643/26, LSDPS, LSTPS, LSFPS, and LS7PS 4.1.8 Dead-ended cable. Cables installed through error or rendered useless as a result of

43、modification shall be removed. 4.1.9 Gun mounts. Cables to gun mounts and directors shall be routed from the deck below through the center column. Watertight integrity shall be maintained. Cable shall be located and installed to avoid the possibility of chafing. Nonflexing cables shall terminate in

44、submersible or watertight changeover connection boxes at the point of connection to the flexible cables. Length of flexible cables between changeover connection boxes and the slack cable enclosure shall be kept to a minimum. The slack cable enclosure shall be entered through stuffing tubes. In compa

45、rtments containing hydraulic systems, the cable installation shall not impair the air-tightness or watertightness of decks and bulkheads forming the boundaries of the compartment. 4.1.10 Rotating missile launchers. Cable connections to rotating missile launchers shall comply with the Government Furn

46、ished Information (GFI) for the specific ordnance system being connected. 4.1.11 Ballistic structures. Cables shall not be supported or attached to ballistic structures unless approved by NAVSEA. Preferences for cable routing to avoid ballistic structure is as follows: a. First preference shall be g

47、iven to routing cables on the inboard or after bulkheads in the forward half of the ship, and on the inboard or forward bulkheads in the after half of the ship. b. Second preference shall be given to routing cables on channels, or in cable racks on angles, attached to overhead deck beams. 4.1.12 Bul

48、kheads and overheads. Cables shall not be routed on the outboard or forward bulkheads in the forward half of the ship, and on the outboard or after bulkheads in the after half of the ship, when the plating is 50 pounds per square foot (lb/ft2) or heavier. This routing shall also be avoided for light

49、er plating unless no other route is feasible. The installation of cables on the overhead and on bulkheads shall comply with NAVSEA standard methods specified herein. Cables for vital systems such as interior communication and weapons control systems shall not be secured to the overhead, or to shell planking, to shell plating or to ballistic bulkheads.
