Innovation starts at the core of C7™ Overhead Conductor
Southwire's newest transmission conductor is the result of a partnership with Celanese Corporation — engineers of advanced polymers, resins and thermoplastics. C7 Overhead Conductor features a multi-stranded, carbon-fiber composite core to provide greater flexibility, reliability and single-failure tolerance. Its advanced core and polymer coating provides C7 Overhead Conductor with unprecedented heat resistance and a 40+ year service life expectancy.
From new lines to reconductoring, C7 Overhead Conductor is engineered to withstand the rigors of installation and operation. Utility providers can reduce new-line costs by installing with standard line tools on existing structures and foundations. Reconductoring is also more affordable, as C7 Overhead Conductor has nearly double the capacity with less sag than same-diameter ACSR.
As part of Southwire's complete set of overhead transmission conductors, C7 Overhead Conductor fulfills a market need for increased performance, capacity and affordability. It is available in Trapezoidal Wire (TZ), Aluminum Zirconium (AlZr) and O-Temper versions to better suit your specific needs.
