Anotation

This specification covers cored, annular, concentric-lay-stranded conductors made from round soft copper wires either uncoated or coated with tin for use as electrical conductors. The core may be of any materials and its size and surface firmness as a base for the overlaid wires shall be adequated to prevent forcing or dropping of any wire out of its layer position. No splice shall be made in the conductor as a whole, welds or brazes may be made in the finished individual wires. The materials shall conform to the required nominal conductor size, number of layers of wires, number, diameter, lay-up wires, approximate core diameter, and maximum conductor diameter. The mass per unit length and electrical resistance of a unit length of stranded conductor are a function of the length of lay and shall be calculated. The are of cross section of a conductor shall be considered to be the sum of the cross-sectional areas of its component wires at any section when measured perpendicularly to their individual axes.
