*Resistance at 75ºC total temperature, based on ambient of 25ºC plus 50ºC rise due to heating effect of current. The approximate magnitude of current necessary to produce the 50ºC rise is 75% of the “Approximate Ampacity at 60 Hertz.” **Based on a conductor temperature of 125ºC and an ambient of 25ºC. A 2 ft/s wind speed and Emissivity = 0.5. The above data are nominal values and are subject to normal manufacturing tolerances. Electrical performance values, including ampacity and short-circuit ratings, are based on standard test methods and calculation procedures and may vary depending on application and operating conditions.

Utility Steel Strand

Guy, Static & Messenger Wire, Galvanized or Zinc-5% Aluminum Alloy Coated, 3 Strand, 7 Strand & 19 Strand – Steel

Commonly referred to as galvanized guy wire, it’s used for structural support and stabilization in electric utility and communications infrastructure including, pole guying, overhead static and ground wire applications, and messenger cable support. It provides high tensile strength and long-term corrosion resistance in outdoor environments. Galvanized (zinc-coated) strand is for reliable performance in standard utility installations, while zinc-5% aluminum alloy coated strand offers enhanced corrosion protection for coastal, industrial, and extended design-life applications. Designed to anchor and stabilize poles and towers, support aerial cable systems, and provide dependable grounding continuity where uninterrupted mechanical and electrical performance is required. Stocked primarily in extra high strength (EHS) grade. Other grades available upon request.
