Historical (view previous versions of standard)
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.
