Anotace

This specification covers shaped wire compact concentric-lay-stranded aluminum conductors, steel supported (ACSS/TW) for use as overhead electrical conductors. Electric-butt welds, cold-pressure welds, and electric-butt, cold upsed welds in the finished individual aluminum wires composing the conductor may be made during the stranding process. The electrical resistivity of the material shall meet the minimum resistivity specified. The rated strength of the completed conductor may be determined by mechanical tests. Mass and density of the conductors shall be determined.
