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

  • While insulation is rated to 1-hour exposure of 500°F, alloy armor wires may have reduced corrosion resistance at temperatures above 400°F.
  • The armor wires are made of corrosion resistant alloy steel suitable for moderate H2S and CO2 environments.
  • Conductor has nickel plated wires adhering to ASTMB355 Class 10 for increased corrosion resistance.
  • Core assembly – Copper strand consists of six wires around one center wire. 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.
