Abstract

This specification covers stranded conductors made from round copper wires, either uncoated or coated with tin, lead, or lead alloy for general use in insulated conductor assemblies for electrical purposes. These conductors shall be composed of one or more roller shaped or die closed layers of helically laid wires using the single input wire. For stranded conductors, the direction of lay of the outer layer shall be leeft hand and may be reversed or unidirectional/unilay in successive layers. Test for the physical and electrical properties of wires composing conductors made from hard-drawn or medium-hard-drawn wires, uncoated or coated, shall be made before but not after stranding. For the purpose of calculating mass, cross sections, and so forth, the density of the copper shall be taken. The mass and electrical resistance of a unit length of stranded unsealed conductor are a function of the lenght of lay shall be calculated.
