* See attached specification sheet for recommended maximum temperature exposure times.

  • 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 a total of nineteen wires. Conductor resistance is measured at 68° F. Voids in the copper strand are filled with a water-blocking agent to reduce water and gas migration.
  • SUPERSEAL, a special pressure seal agent, is applied between armor layers.
  • The temperature rating assumes a normal gradient for both temperature and weight.
  • All values shown are nominal or typical values.
