* 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 and cables are post tensioned.
* Core assembly – Conductors are bound with conductive tape and voids are filled with conductive paste and string.
* Conductors are "Water Blocked" to reduce water and gas migration. Conductor resistance is measured at 68 deg. F.
* The temperature rating assumes a normal gradient for both temperature and weight.
* Center conductor construction is 7×0.0128". The typical capacitance is decreased by approximately 5 to 10% in comparison to the outer conductors.
* All values shown are nominal or typical values.
