  • Insulation is rated to 500° F. Armor wires are rated to 325° F at low levels of H2S & CO2.
  • The armor wires are made of a corrosion resistant alloy steel. Wires are preformed and cables are post tensioned.
  • The nickel coated copper wires are made of ASTMB355 Class 10 and they are used to increase corrosion protection.
  • 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.
  • Camesa recommends the use of a straight-pull cable head for termination of alloy cable to tool string. Conventional cable head terminations can cause stress cracking on alloy wire and are not recommended for sour service lines.
