Anotation

This specification covers aluminum 1350-H19, 1350-H16 or -H26, 1350-H14 or -H24, 1350-H142 or -H242, and aluminum alloy 8XXX series for tempers ""O"" and H1X or H2X, bare stranded conductors composed of one or more roller shaped or die compressed layers of helically laid wires. The conductors are for general use for electrical purposes. The conductors described in this specification are intended for subsequent insulation or covering. The areas of cross section, the minimum number of wires, and diameters of the finished strand shall conform to the prescribed construction requirements. The rated strength of 1350-H19 conductors shall be taken as the percent of the sum of the strengths of the component wires, calculated using the nominal wire diameters and the specified minimum average tensile strength. The rated strength of 800 series conductors shall be taken as the percent of the sum of strengths of the component wires, calculated using nominal wire diameters and the specified minimum average tensile strength. The approximate mass and electrical resistance may be determined using the standard increments due to stranding. Mechanical and electrical tests shall be made for not annealed and annealed conductors after stranding. Temperature correction factors for conductor resistance shall be provided when dc resistance is measured at specified temperatures.
