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.
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.
SUPERSEAL, a pressure seal agent is applied between armor layers.
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.
