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 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.
All values shown are nominal or typical values.
CRUSH RESISTANT. Can withstand 10:1 tension differentials.
