Moisture-proof corrosion-proof coaxial cable

Abstract

A moisture-proof corrosion-proof coaxial cable comprises an inner conductor, an insulating layer, an outer conductor and an outer sheath, wherein an inner crusting layer is arranged between the inner conductor and the insulating layer; the outer conductor is composed of an aluminum foil layer and a weave layer; a filling layer is arranged between the outer conductor and the outer sheath; and the inner conductor, the inner crusting layer, the insulating layer, the aluminum foil layer, the weave layer, the filling layer and the outer sheath are radially arranged from inside to outside in sequence. Self-prepared mineral oil mixture is employed, so that corrosions of moisture and saline solution on aluminum foil and woven wire are prevented and metal oxidation resistance performance is good; the self-prepared mineral oil mixture is employed, so that, during production, filling process is simple and convenient, production efficiency is high and quality is stable; the self-prepared mineral oil mixture, which is a high molecular weight organic matter itself, effectively controls filling amount, helps to solve the problem of incompatibility between traditional ointments and cable sheath materials and meanwhile the transmission performance of the cable is not influenced.

Description

(1) Technical field [0001] The invention relates to a cable, in particular to a novel moisture-proof and corrosion-proof coaxial cable. (2) Background technology [0002] Once the coaxial cable is eroded by moisture, moisture, saline and alkali, the outer conductor will be oxidized and corroded, and the aluminum foil and braided wire of the outer conductor will gradually become brittle and deteriorated, resulting in deterioration of electrical and physical properties and loss of use function. [0003] And the way usually taken at present is to be filled with moisture-proof anti-corrosion ointment between outer conductor and sheath. There are following disadvantages in using this measure: [0004] 1) The anti-corrosion ointment itself contains a certain amount of water, and if it is not handled properly, it will be counterproductive; [0005] 2) There is a compatibility problem between the ointment and the sheath material. If the amount is too large, the ointment will preci...

AI Technical Summary

Problems solved by technology

[0004] 1) The anti-corrosion ointment itself contains a certain amount of water, and if it is not handled properly, it will be counterproductive;

[0005] 2) There is a compatibility problem between the ointment and the sheath material. If the amount is too large, the ointment will precipitate through the surface of the sheath, or force the small molecules in the sheath to precipitate;

[0006] 3) It is difficult to control in production by using the grease method, and the operators are disgusted;

[0007] 4) It is difficult to control the amount of waterproof ointment added, resulting in many quality problems, large waste, and low production efficiency
