Southwire Company LLC, a leading manufacturer of high-voltage underground cable systems, aims to boost cable production and quality with the Maillefer Round Premium Package. Slated for installation later this year as an upgrade to an existing line, Southwire will be the first in North America to employ this capability. The company will be able to produce rounder cables as large as 6 inches (152mm) in diameter that weigh as much as 25 pounds per foot at production speeds faster than previous technology has allowed. Southwire will also be able to reduce material usage, which is significant due to the many plastic layers extruded over the conductor for safety and durability.

“We have a strong, long-standing association with Maillefer, a Davis-Standard company. Davis-Standard has augmented this relationship by providing local support for parts, service and purchasing, further improving the process,” said Chris McGill, Plant Manager at Southwire. “This upgrade to our vertical CV line not only supports better production, but it also benefits cable installers because rounder cables are easier to connect for longer lengths in the field.”

Southwire’s high-voltage power cable is engineered to run underground for power transmission and distribution from generation points to substations over long distances. Due to the trend away from bare conductors and overhead transmission lines, demand for this type of cable has increased dramatically. With Southwire’s international customer base, the upgrade will enable them to more effectively address current and future market growth. In addition to equipment, Maillefer will provide installation support, commissioning and training.

“We are excited to have a North American customer install and use this technology,” said John Zachow, Vice President of Davis-Standard Wire and Cable Systems. “This is going to differentiate their product while improving all aspects of production for this type of cable.”
