Standard Specification for Cored, Annular, Concentric-Lay-Stranded Copper Conductors
The following bibliographic material is provided to assist you with your purchasing decision:
Scope
1.1 This specification covers cored, annular, concentric-lay-stranded conductors made from round soft copper wires, either uncoated or coated with tin, lead, or lead alloy for use as electrical conductors (Explanatory Note 1 and Note 2).
1.2 The constructions prescribed herein are suitable for bare conductors, or for conductors to be covered with weather-resistant (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 0).
1.3 Cored, annular conductor constructions not included in this specification shall be specifically agreed upon between the manufacturer and the purchaser when placing the order.
1.4 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.
1.5 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.
