• B-779 Shaped Wire Compact Concentric-Lay-Stranded Aluminum Conductors, Steel-Reinforced (ACSR/TW).

Southwire's Motion-Resistant Conductor is composed of a combination of round and shaped wires of varying diameters and cross-sections. The wires are stranded in such a way to give the cable a spiraling elliptical shape. This spiraling elliptical shape disrupts the forces created by steady cross winds which cause cable vibration, by presenting a continuously changing projected cable diameter to the wind. The spiral shape, together with less torsional stiffness and varying bending stiffness also reduces or eliminates cable galloping due to combined ice and wind loads. High strength steel core and aluminum clad steel core is also available. AAC Motion-Resistant Conductor is available upon request.
