CUES manufactures both single-conductor and multi-conductor systems. Both single-conductor and multi-conductor systems equally represent current technology in this industry and are in use daily throughout the United States and the rest of the world. Single-conductor cable contains one coaxial conductor pair surrounded by insulation, then a spiral wound steel armor, then a second steel armor spiral wound in the opposite direction (the two steel armors also act as tensile-load-bearing members; the outer armor also acts as the cable’s jacket). Multi-conductor cable contains one coaxial conductor pair and ten individual conductors wound in a spiral fashion surrounded by a braided Kevlar tensile-load-bearing member embedded in an extruded nylon armor/jacket.
