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.
Manufacturer recommends to maintain tension profle at all times, or conductor crushing can occur, and conductor failure is not always immediate. If the tension profle is changed, it should be corrected immediately.
Core assembly – Conductors are stranded and covered with ETFE plastic jacket.
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.
