The following bibliographic material is provided to assist you with your purchasing decision:

This specification covers hard-drawn round copper-clad steel electrical conductor for CATV drop wire (coaxial cable center conductor). The wire shall be composed of a steel core with a substantially uniform and continuous copper cladding thoroughly bonded to it throughout. The size shall be expressed as the diameter of the wire. The steel wire shall conform to the prescribed tensile strength, elongation, and breaking strength. Requirements for (1) tension and torsion tests, (2) method of determining the electrical resistance, (3) cladding uniformity in terms of thickness, and (4) joint construction are detailed. The prescribed density of the wire to be taken for calculating mass/unit length, cross section, and so forth is given.



1.1 This specification covers 21 % conductivity hard-drawn round copper-clad steel wire for coaxial cable center conductors (Note 1). Note 1 - Wire ordered to this specification is not intended for redrawing since it is furnished in the hard-drawn temper. If wire is desired for the purpose, the manufacturer should be consulted.

1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
