  • The armor wires are high tensile, Galvanized Extra, Extra Improved Plow Steel (GEEIPS), and coated with anti-corrosion compound for protection during shipping and storing. Wires are preformed and cables are post tensioned.
  • The manufacturers’ recommended tension profile must be maintained at all times, or conductor crushing can occur, and conductor failure is not always immediate. If the tension profile is changed, it should be corrected immediately.

* All values shown are nominal or typical values.
