The armor wires are high tensile, Galvanized Extra Improved Plow Steel (GEIPS), and coated with anti-corrosion compound for protection during shipping and storing. Wires are preformed.
Core assembly – Copper strand consists of six wires around one center wire. Voids in the copper strand are flled with a waterblocking agent to reduce water and gas migration. Conductor resistance is measured at 68° F.
The temperature rating assumes a normal gradient for both temperature and weight.
All values shown are nominal or typical values.
