Hard-Drawn Copper, Grooved Contact Wire, 30% SouthWear®

Contact / Trolley Wire for Mass Transit and Industrial Haulage



This product offers the industry's most commonly used, best conductivity, wear characteristics and tensile strength properties. Hard Drawn Copper contact/trolley wire is available in the ASTM configurations: grooved, figure 8, or figure 9.

Applications and Features:

SouthWear® Contact Wire is mechanically rugged commonly used as an overhead power source on streetcars, trolleys, electric trolley buses, light rail, commuter rail and high speed railway mass transit systems. Features a 30% wear mark on the side of the wire to provide visual identification when the percentage of wear has met or exceeded the industries allowable safe tolerance for wear. Southwire hard drawn copper trolley wire is ideal for line speeds of up to 100 mph (160 km/h).
