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 – Conductors are bound with conductive tape and voids are flled with conductive fller and string.
Conductors are “Water Blocked” 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.
Center conductor construction is 6x0.0142” with a non-conductive center member. The typical resistance is reduced by
approximately 5 to 10% and the capacitance is increased by approximately 5 to 10% in comparison to the outer conductors.
All values shown are nominal or typical values
