1、INCH-POUND MIL-DTL-3432J 22 December 2009 SUPERSEDING MIL-DTL-3432H 23 January 2006 DETAIL SPECIFICATION CABLES, (POWER AND SPECIAL PURPOSE) AND WIRE, ELECTRICAL (300 AND 600 VOLTS) This specification is approved for use by all Departments and Agencies of the Department of Defense. 1. SCOPE 1.1 Scop

2、e. This specification covers single and multiple conductor cables with and without shields for use in 300 and 600 volts root mean square (rms) applications (see 6.1). 1.2 Classification. Cables covered in this specification are furnished in accordance with the type designation specified and are clas

3、sified by the element thereof. 1.2.1 Type designation. The type designation is formed as follows: M 3432 - 08 HG E (2/16S-4/12) SJ 1090 Part or Identifying Number (PIN) (1.2.1.1) Total number of conductors (1.2.1.2) Class (1.2.1.3) Flexibility (1.2.1.4) Conductor data (1.2.1.5) Shielding under jacke

4、t (1.2.1.6) Outside diameter (1.2.1.7) 1.2.1.1 PIN. Cables covered by this specification are identified by “M3432“ followed by a hyphen. 1.2.1.2 Total number of conductors. The total number of conductors (see 6.3.1) in a cable, exclusive of ground wires (see 6.3.2 and 6.3.4), is identified by a two-

5、digit number. For cables with less than 10 conductors, a “0“ precedes the number of conductors (example - 04 means 4 conductors) in a multiple conductor power cable.

The class of cables is identified by a two letter symbol, the first letter of which designates the duty (see 6.1) in accordance with table I. The second letter indicates the application of the cables in accordance with table I

11、lyisoprene may be blended with natural rubber. 1.2.1.4 Flexibility. Flexibility of a cable is based upon the flexibility of the conductors within the cable. All conductors and ground wires within the same cable will be of the flexibility designated (see 3.1.1 and 3.1.2). The flexibility is identifie

12、d as follows: S - Semi-flexible F - Flexible E - Extra-flexible 1.2.1.5 Conductor data. 1.2.1.5.1 Number and size of individual conductors. The number of individual conductors of the same wire size are designated by that number followed by a slash and a number indicating the conductor wire size. For

13、 example: “3/22“ indicates 3 number 22 AWG conductors. When cables are made up of different wire sizes, each different wire size is individually represented, with a dash separating each different wire size. For example: “-6/14-1/8“ indicates 6 number 14 AWG conductors and 1 number 8 AWG conductor. P

14、rovided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-DTL-3432J 3 1.2.1.5.2 Unshielded grouped conductors. Conductors twisted together to form a group (such as pairs, triples, quads, etc.) are designated, immediately following the wire size, by “x“ foll

15、owed by the number of these conductor groups contained in the cable. For example, “2/20 x 1“ indicates 2 number 20 AWG conductors twisted together to form a pair; “3/22 x 4“ indicates four groups, each group consisting of 3 number 22 AWG conductors twisted together to form a triple. 1.2.1.5.3 Shield

16、ing. 1.2.1.5.3.1 Grouped shielding. When one or more groups of copper conductors have a common shield over each conductor group, the designator “S x (number of groups)“ follows the wire size; for example, “2/22 S x 6“ indicates six pairs of number 22 AWG conductors, with a shield over each pair. Whe

17、n a single group has an overall shield, the designation “x 1“ is to be omitted since conductors under a shield are twisted to form one group, for example; “2/20 S“ indicates one twisted pair of number 20 AWG conductors under a common shield. 1.2.1.5.3.2 Individual shielding. When each conductor of t

18、he same size is individually shielded, the letter “I” follows the letter “S“. For example: “3/14 SI indicates 3 number 14 AWG conductors, each conductor individually shielded. A shielded single conductor is to be designated by the letter “S“ instead of “SI“. For example: “1/18 S“ indicates 1 number

19、18 AWG conductor shielded. 1.2.1.5.4 Uninsulated ground drain wires. Uninsulated ground drain wires are designated in the same manner as conductors specified in 1.2.1.5 except the letter “R“ is to follow the wire size. For example: “3/8 R“ indicates 3 number 8 AWG ground wires. Uninsulated ground wi

20、res are not counted in the total number of conductors. 1.2.1.5.5 Cabling. All conductors and groups that are cabled together beneath the jacket, and under the jacket shield, should be enclosed in parentheses. For example: “(2/20 x 2 - 3/18)“ indicates a cable made up of two twisted pairs of number 2

21、0 AWG conductors and 3 number 18 AWG conductors. 1.2.1.5.6 Cable configuration. Cables composed of two conductors laid parallel are to be designated by the letter “F“, which is to follow the conductor number. For example, “2F/8“ indicates 2 number 8 AWG conductors laid parallel. 1.2.1.6 Shielding un

22、der the jacket. When single shielding is over all conductors and beneath the jacket, the letters “SJ“ follows the parentheses that enclose the conductor data. When double shielding beneath the jacket is specified, the letters “SSJ“ will follow the parentheses that enclose the conductor data. No lett

23、ers are used if an overall shield beneath the jacket is not present. 1.2.1.7 Outside diameter. 1.2.1.7.1 Cables (except parallel conductors). The outside diameter of the cable is indicated by four significant figures expressing the diameter in mils (thousandths of an inch) to the nearest figure divi

24、sible by five. If a tolerance other than that specified in 3.2.8.1 is required, it is indicated by placing the tolerance immediately after this element of type designation (see 1.2.1.8b and 1.2.1.8f). 1.2.1.7.2 Parallel conductor cables. The outside diameter of the parallel conductor cable should be

25、 designated by giving the major diameter followed by a slant, followed by the minor diameter. The diameter, either major or minor, should be indicated in mils (thousandths of an inch) by four significant figures. If a tolerance other than that specified in 3.2.8.2 is required, it should be indicated

26、 by placing the tolerance immediately after the major or minor diameter. 1.2.1.8 Use and examples of type designations. Use of type designations formed as indicated in 1.2.1 is not intended to limit the number of cable types procured under this specification. Representative examples of type designat
