ACSR Motion-Resistant Conductor.

Bare Aluminum Conductor, Steel Reinforced.

APPLICATIONS

Southwire's Motion-Resistant Conductor is designed for overhead distribution and transmission lines. It is a galloping- and

vibration-resistant, bare aluminum construction, designed for use in overhead applications subject to aeolian vibration and

galloping due to wind and ice. Motion-Resistant conductors can be strung to the maximum allowable tension limits without the

Stranded Steel Core for Aluminum Conductors, Steel Reinforced (ACSR).

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

CONSTRUCTION

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
