1、 INCH-POUND A-A-59551A SUPERSEDING 22 October 2009 A-A-59551 27 October 2000 COMMERCIAL ITEM DESCRIPTION WIRE, ELECTRICAL, COPPER (UNINSULATED) The General Services Administration has authorized the use of this commercial item description for all federal agencies. 1. SCOPE. This commercial item desc
2、ription (CID) covers the general requirements for solid, bunch-stranded, concentric-lay-stranded, and rope-lay-stranded round, uninsulated, copper conductors for use in electrical wire. Wires covered by this CID are intended for commercial/industrial applications. 2. CLASSIFICATION/PART OR IDENTIFIC
3、ATION NUMBER (PIN). This CID uses a classification system which is included in the PIN shown in the following example (see 7.1). The PIN is made up of the basic CID number and a five-element alphanumeric dash number. Example of PIN: AA59551C64A1T AA59551C64A 1 TB No coating N Nickel (class 2 of ASTM
4、 B355) S Silver Coating T Tin C Nickel (class 10 of ASTM B355) E Nickel (class 27 of ASTM B355) 1 Soft or drawn and annealed (annealed for type H only). Temper 2 Medium hard drawn. 3 Hard drawn. 4 Unannealed (type H silver or nickel coated conductors only). Class: Class letters as shown in tables II
5、I, IV, V, and VI are to be used, except that all type S wires are class S. Size: Wire sizes are indicated by the size designators used in tables II, III, IV, V, and VI.

The type designates the construction of the wire (see table I and 3.3). The following types are available (see 7.5): S - Solid single
9、strand. C - Concentric-lay-stranding. R - Rope-lay-bunched member stranding. E - Rope-lay-concentric member stranding. B - Bunch-stranding. H - Hookup conductor. 2.2 Class. The class defines the construction details within a particular type wire (see 7.2). Type S wires are classified as class S for
10、the purpose of this CID. 2.3 Temper. The available tempers per wire type are listed in table I (see 7.5). 2.4 Wire size. For solid wires of American Wire Gauge (AWG) 56 thru 0000 (4/0), the wire size is indicated by AWG size as specified in ASTM B258. For all wires larger than 4/0, the size is indic
11、ated by the cross sectional area in circular mils (thousandths of an inch). For sizes of stranded wires smaller than 250,000 circular mils, the AWG number that is the closest but larger in size is used except for hookup wire (type H), in which only even AWG numbers are used.
