VR2® Conductor – Southwire Company, LLC’s twisted pair conductor design – provides vibration and galloping resistance without the schedule delays associated with bagging problems during installation. Now, Southwire’s ZTACSR/VR2 conductor provides higher thermal resistance allowing for greater ampacity without having to increase conductor size.
Southwire Company’s ZTACSR/VR2® conductor is composed of two identical bare conductors twisted together. This varying profile disrupts the wind forces that cause conductor vibration, which helps to reduce galloping due to ice and wind. ZTACSR/VR2 is available with multiple conductor types, and in sizes up to 2 x 1113 kcmil.
ZTACSR/VR2 conductor is designed for overhead applications subject to aeolian vibration and galloping due to ice and wind. ZTACSR/VR2 can be installed to the maximum allowable tension limits without the need for additional vibration protection
