1. A coaxial cable, comprising:
- an elongate center conductor;
a dielectric layer surrounding said center conductor;
an outer conductor comprising aluminum or an aluminum alloy surrounding said dielectric layer; and
a corrosion-inhibiting coating on at least an outer portion of said outer conductor and comprising a water-insoluble corrosion-inhibiting compound selected from the group consisting of petroleum sulfonates and salts thereof, said corrosion inhibiting coating further including residual amounts of an oil dispersant, and residual amounts of a stabilizer selected from the group consisting of propylene glycol ethers, propylene glycol ether acetates, ethylene glycol ethers and ethylene glycol ether acetates.

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.

20. A coaxial cable, comprising:
-
an elongate center conductor;
a dielectric layer surrounding said center conductor;
an outer conductor comprising aluminum or an aluminum alloy surrounding said dielectric layer; and
a corrosion-inhibiting coating on at least an outer portion of said outer conductor, said corrosion-inhibiting coating formed by beating a composition comprising a water-insoluble petroleum sulfonate corrosion-inhibiting compound dispersed in an 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 such that a substantial portion of the oil and the stabilizer evaporate to leave a non-tacky, non-greasy corrosion-inhibiting coating comprising said corrosion-inhibiting compound on said outer conductor. - View Dependent Claims (21)
