Anotace textu normy ASTM B786/B786M-08(2023) :
This specification covers the standard requirements for bare combination unilay-stranded conductors made from round wires of aluminum 1350 and 8000 series of aluminum alloys, for insulated conductors to be used for electrical purposes. Aluminum 1350 wires in tempers -H19, -H16 or -H26, -H14 or -H24, and -H142 or -H242 and 8000 series aluminum alloy wires in tempers “0” and H1X or H2X are permitted. These conductors shall be constructed with a central core wire surrounded by two layers of helically laid wires, resulting in an outer diameter equal to the compressed-stranded equivalent conductors. Electric-butt welds, cold pressure welds, or electric-butt cold-upset welds may be made in the finished individual wires composing the conductor. Mechanical (tension) and electrical tests shall be performed on the wires composing the conductors that are annealed and not annealed after stranding. The mass and electrical resistance of a unit length of stranded conductor shall be determined as a function of the length of lay. The conductors shall meet the breaking strength, tensile strength, and bending strength requirements.
