First Claim
Patent Images
1. A method of making a coaxial cable, comprising the steps of:
- advancing a center conductor along a predetermined path of travel;
applying a dielectric layer around the center conductor;
applying an outer conductor around the dielectric layer; and
applying a corrosion-inhibiting composition to said outer conductor, said corrosion-inhibiting compound comprising a corrosion-inhibiting compound dispersed in a paraffinic oil, and a stabilizer selected from the group consisting of propylene glycol ethers, propylene glycol ether acetates, ethylene glycol ethers and ethylene glycol ether acetates, the corrosion-inhibiting compound being present in the composition in an amount of from about 5 to about 40% by weight, the oil being present in an amount of from about 50 to 90% by weight, and the stabilizer being present in an amount of from about 1 to about 10% by weight.

Abstract
The present invention is a corrosion-protected cable, a method of making a corrosion-inhibiting cable, and a corrosion-inhibiting composition. The corrosion-inhibiting composition includes a water-insoluble corrosion-inhibiting compound dispersed in an oil, and a stabilizer selected from the group consisting of propylene based glycol ethers, propylene based glycol ether acetates, ethylene based glycol ethers and ethylene based glycol ether acetates. The corrosion-inhibiting composition is preferably applied to the outer conductor of the coaxial cable, e.g., by wiping or by immersion, and heated to provide a corrosion-inhibiting coating that is not tacky or greasy.
