Method for manufacturing a coaxial cable
View Patent ↗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.
1. A method for manufacturing a coaxial cable, the method comprising the steps of:
extruding a dielectric around a center conductor;
surrounding the dielectric with an outer conductor;
applying a corrosion-inhibiting composition to the outer conductor, the corrosion-inhibiting composition consisting essentially of a synthetic sulfonate salt dispersed in a paraffinic mineral oil, the synthetic sulfonate salt being present in the composition in an amount of from about 5% to about 10% by weight, the paraffinic mineral oil being present in the composition in an amount of from about 90% to about 95% by weight; and
surrounding the outer conductor with a jacket.
2. The method as recited in claim 1 , further comprising the step of heating the coaxial cable to partially evaporate the corrosion-inhibiting composition.
3. The method as recited in claim 1 , wherein the synthetic sulfonate salt has an activity of about 67%.
4. The method as recited in claim 1 , wherein no stabilizer is employed to maintain the dispersion between the synthetic sulfonate salt and the paraffinic mineral oil.
5. The method as recited in claim 1 , wherein said step of applying a corrosion-inhibiting composition to the outer conductor comprises wiping an outer surface of the outer conductor with the corrosion-inhibiting composition.
6. The method as recited in claim 1 , wherein said step of applying a corrosion-inhibiting composition to the outer conductor comprises immersing the outer conductor in the corrosion-inhibiting composition.
7. The method as recited in claim 1 , wherein said step of applying a corrosion-inhibiting composition to the outer conductor comprises the steps of:
applying the corrosion-inhibiting composition to a tape layer of the outer conductor; and
applying the corrosion-inhibiting composition to a braid layer of the outer conductor.
8. The method as recited in claim 7 , wherein the tape layer is laminate tape having a layer of aluminum and a braid layer is formed from interwoven aluminum or copper wires.
9. A method for manufacturing a coaxial cable, the method comprising the steps of:
extruding a dielectric around a center conductor;
