VR2®- ACSR Vibration Resistant

Application

VR2TM1 cable, a vibration-resistant, bare aluminum construction, is designed for use in overhead applications subject to Aeolian vibration and galloping due to wind and ice. VR2TM cable can be strung to the maximum allowable tension limits without the need for additional vibration protection.

Standards & References

Southwire's VR2TM cable meets or exceeds the following ASTM specifications for the subconductor of each conductor assembly:

B-231 Aluminum Conductor, Concentric-Lay-Stranded
B-232 Aluminum Conductor, Concentric-Lay-Stranded, Coated Steel Reinforced (ACSR).

Construction

Southwire's VR2TM cable is composed of two identical bare conductors twisted together with a lefthand lay. This gives the cable a figure 8 spiral shape. This spiral shape disrupts the forces created by steady cross winds which cause cable vibration by presenting a continuously changing projected cable diameter to the wind. This spiral shape, together with less torsional stiffness and varying bending stiffness also reduces or eliminates cable galloping due to combined ice and wind. VR2TM is engineered with a lay length that changes with conductor diameter. The engineered lay ensures that the product will install without bagging issues while still providing equal or better resistance to Aeolian vibration and ice galloping. The component conductors of VR2TM cable can be conductor types AAC, ACSR, AAC/TW, or ACSR/TW meeting the requirements of the appropriate ASTM standard. Other sizes available upon request.
