The aluminum and galvanized steel wires for standard constructions covered by this standard shall have the diameters specified in the table. A tolerance of ± 2 percent for galvanized steel wires shall be permitted on the nominal diameter specified in this table. The sizes of standard aluminum conductors, galvanized steel reinforced shall be as given in the table.
There shall be no joint, except those made in the base rod or wire before final drawing, in steel wires forming the core of a steel reinforced aluminum conductor, unless the core consists of seven or more galvanized steel wires. In the later case joint in individual wires are permitted in addition to those made in the base rod before final drawing, but no two such joint shall be less than 15 meters apart in the complete steel core. Joint in galvanized steel cable shall be made by resistance butt-welding or brazing and shall be protected against corrosion.
