1、Designation: B173 10Standard Specification forRope-Lay-Stranded Copper Conductors Having Concentric-Stranded Members, for Electrical Conductors1This standard is issued under the fixed designation B173; the number immediately following the designation indicates the year oforiginal adoption or, in the

2、 case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1. Scope1.1 This s

3、pecification covers bare rope-lay-stranded con-ductors having concentric-stranded members made from roundcopper wires, either uncoated or coated with tin, lead, orlead-alloy for use as electrical conductors (Explanatory Note 1and Note 2).1.2 Coated wires shall include only those wires with fin-ished

4、 diameters and densities substantially equal to the respec-tive diameters and densities of uncoated wires.1.3 The values stated in inch-pound or SI units are to beregarded separately as standard. Each system shall be usedindependently of the other. Combining values from the twosystems may result in

5、nonconformance with the specification.For conductor sizes designated by AWG or kcmil, the require-ments in SI units have been numerically converted fromcorresponding values, stated or derived, in inch-pound units.For conductor sizes designated by SI units only, the require-ments are stated or derive

6、d in SI units.1.3.1 For density, resistivity, and temperature, the valuesstated in SI units are to be regarded as standard.2.

10、tors consisting of 7 to 61 rope-lay-stranded members, each of which consists of 7 to 19concentric-stranded wires, with total conductor sizes rangingfrom No. 14 AWG (2.08 mm2) to 5 000 000 cmil (2534 mm2).(Typical use is for rubber-sheathed conductor, apparatus con-ductor, portable conductor, and sim

11、ilar applications.)3.1.2 Class HConductors consisting of 19 to 91 rope-lay-stranded members, each of which consists of 7 to 19concentric-stranded wires, with total conductor sizes rangingfrom No. 9 AWG (6.63 mm2) to 5 000 000 cmil (2534 mm2).Class K construction produces a conductor with greater fle

12、x-ibility than class G. (Typical use is for rubber-sheathed cordand applications where flexibility is required such as ontake-up reels over sheaves and extra-flexible apparatus con-ductor.)4. Ordering Information4.1 Orders for material under this specification shall includethe following information:
