ASTM B801 Standard Specification for Concentric-Lay-Stranded Conductors of 8000 Series Aluminum Alloy for Subsequent Covering or Insulation
ASTM B801次级涂层或绝缘的8000系列铝合金同芯绞捻导线标准规范

This specification covers aluminum alloys in the 8000 series in tempers 0 and H1X or H2X bare compact-round, compressed and conventional concentric-lay-stranded conductors made from round or shaped wires used as covered or insulated electrical conductors. These conductors shall be composed of a central core surrounded by one or more compacted, compressed or conventional layers of helically applied wires. Joints may be made in any of the wires of any stranding by electric-butt welding, cold-pressure welding, or electric-butt, cold-upset welding. The construction of the conductors shall conform to the construction requirements prescribed in this specification. Tests for the mechanical and electrical properties of wire composing the conductor shall be made before standing. Wires annealed before stranding shall meet the requirements of the prescribed specification. The tensile requirements shall be the same as those for round wires of equal nominal area.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

1. Scope
1.1 This specification covers aluminum alloys in the 8000 series cited in B 800 in tempers "0" and H1X or H2X bare compact-round, compressed and conventional concentric-lay-stranded conductors made from round or shaped wires used as covered or insulated electrical conductors. These conductors shall be composed of a central core surrounded by one or more compacted, compressed or conventional layers of helically applied wires (Explanatory Note 1 and Note 2).
1.2 The SI values for resistivity are regarded as standard. For all other properties, the inch-pound units are regarded as standard and the SI units may be approximate.
1.3 Sealed conductors that are intended to prevent longitudinal water propagation are also permitted within the guidelines of this specification.
