CORROSION RESISTANT COAXIAL CABLE
Corrosion resistant coaxial cable. In one example embodiment, a method for manufacturing a coaxial cable includes various steps. First, a dielectric is extruded around a center conductor. Next, the dielectric is surrounded with an outer conductor. Then, a corrosion-inhibiting composition is applied to the outer conductor. Finally, the outer conductor is surrounded with a jacket. The corrosion-inhibiting composition includes a synthetic sulfonate salt dispersed in a paraffinic mineral oil. The synthetic sulfonate salt is present in the composition in an amount of from about 5% to about 10% by weight. The paraffinic mineral oil is present in the composition in an amount of from about 90% to about 95% by weight.
