Description / Abstract:

This specification covers cored, annular, concentric-laystranded conductors made from round soft copper wires, either uncoated or coated with tin for use as electrical conductors (Explanatory Note 1 and Note 2)

The constructions prescribed herein are suitable for bare conductors, or for conductors to be covered with weatherresistant (weather-proof) material, or for conductors to be insulated with rubber, varnished cloth, or impregnated paper, except types such as “oil-filled” or “gas-filled” (Explanatory Note 3)

Cored, annular conductor constructions not included in this specification shall be specifically agreed upon between the manufacturer and the purchaser when placing the order

These constructions are not recommended for use as electric furnace leads where great flexibility is required and special conductor designs are indicated in consideration of the particular service requirements

The SI values for density are regarded as the standard. For all other properties the inch-pound values are to be regarded as standard and the SI units may be approximate
