Insulation is rated to 500° F. Armor wires are rated to 425° F at low levels of H2S + CO2.
The armor wires are made of a corrosion resistant alloy steel. Wires are preformed.
The nickel coated copper wires are made according to the ASTMB355 Class 10 and they are used to increase corrosion
protection.
Core assembly – Copper strand consists of nineteen wires. Conductor resistance is measured at 68° F. Voids in the copper
strand are flled 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.
