Southwire’s innovative 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 provide our C7 Overhead Conductor with unprecedented sag/tension performance and a 40+ year service life expectancy. From new lines to reconductoring, the C7 Overhead Conductor is engineered to withstand the rigors of installation and operation. Utilities can reduce new-line costs by designing lines with fewer structures or shorter structures, reducing overall construction costs. Line upgrades are also more affordable, as the C7 Overhead Conductor can be used in reconductoring applications to double the ampacity of an existing ACSR, with less sag, without exceeding existing design tensions. As part of Southwire’s complete set of overhead transmission conductors, the C7 Overhead Conductor fulfills a market need for increased performance, capacity and affordability. It is available in Trapezoidal Wire (TW), Aluminum Zirconium (Al-Zr) and O-Temper versions to better suit your specific needs.
