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 paste 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 7x0.0128”. The typical capacitance is decreased by approximately 5 to 10% in comparison to the outer conductors.
All values shown are nominal or typical values
