Anotácia

This specification covers concentric-lay-stranded conductors made from uncoated hard-drawn round copper wires in combination with hard-drawn round copper-clad steel wires for general use as overhead electrical conductors. The conductors are classified under the following type designations: Type A, Type C, Type D, Type E, Type EK, Type F, Type G, Type J, Type K, Type N, Type P, and Type V. Welds and brazes may be made in copper rods or in copper wires prior to final drawing. Joints may not be made in the finished copper wires composing concentric-lay-stranded composite conductors containing a total of seven wires or less. In other conductors, welds and brazes may be made in the finished individual copper wires composing the conductor. Also, the joints or splices may be made in the finished individual copper-clad steel wires composing concentric-lay-stranded conductors, provided that such joints or splices have a protection equivalent to that of the wire itself and that they do not decrease the strength of the finished stranded conductor below the minimum breaking strength. The density, mass, and resistance of the wires shall be determined.
