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.

Method of making corrosion-protected coaxial cable

An electrical communications element having a foamed plastic insultation extruded about a conductor with said insulation including at least one component with more than 20% by weight of an ultra-high die swell ratio polymer (UHDSRP), preferably around 15% by weight. The UHDSRP is defined as greater than 55% die swell ratio and more preferably greater than 65% die swell ratio. The insulation also preferably includes at least a second component with a high degree of stress crack resistance, such that the combination of (minimally) these polymers will yield an insulation layer that has a unique combination of physical propeties yielding a high degree of foaming, small uniform cell structure, characteristically lower attenuation, and stress crack resistance capable of withstanding greater than 100 hours at 100&#xb0; C. while coiled at a stress level of 1 times the insulation outside diameter without failure (cracking).
