Requirement for Wires6.1 Before stranding, the aluminum wires used shall meet all the requirements of Specification B230/B230M.6.2 Before stranding, the aluminum-clad steel core wires

18、used shall meet all the requirements of Specification B502.7. Joints7.1 Electric-butt welds, cold-pressure welds, or electric-butt, cold-upset welds in the finished individual aluminum wirescomposing the conductor may be made during the stranding process. No weld shall occur within 50 ft (15 m) of a

19、 weld in the samewire or in any other wire of the completed conductor (Explanatory Note 1).7.2 There shall be no joints of any kind made in the finished aluminum-clad steel wires.8.
