* See attached specification sheet for recommended maximum temperature exposure times. 

  • 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 deg. F.
  • The temperature rating assumes a normal gradient for both temperature and weight.
  • Center conductor construction is 7x0.0128". The typical capacitance 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.
