Problems solved by technology

In the past, the cable being sprayed to paint was considered an accidental phenomenon, which should be avoided or at least cleaned up in time. However, from the perspective of actual use, the cable surface being sprayed to paint is common, and it is only theoretically possible to completely avoid it, resulting in Reduced lifetime of marine cables
If a certain section of the entire cable is polluted, the entire cable will need to be replaced in advance, which is not only a serious waste, but also has a great potential safety hazard

Abstract

The invention relates to a marine oil-resistant and paint-aging-resistant instrument cable and a manufacturing method thereof. The method comprises the following steps: extruding an insulating layer on the periphery of a conductor to form insulated cores; pairwise twisting the insulated cores to form twisted pairs; filling gaps of the twisted pairs with flame-retardant polypropylene fiber filling cores; twisting multiple groups of twisted pairs to form a cable core; wrapping the periphery of the cable core with a flame-retardant and fire-resistant longitudinal tape with high thermal resistivity; coating the periphery of the longitudinal tape with an armored woven layer; coating the periphery of the armored woven layer with talcum powder; and extruding an oil-resistant and paint-aging-resistant outer sheath outside the talcum powder. The outer sheath is prepared from the following components in parts by weight: 15 parts of PVC-SG2, 5 parts of LEVAPREN 500HV rubber, 4-7 parts of polypropylene adipate, 2-3 parts of epoxidized soybean oil, 0.6-1 part of tribasic lead sulfate, 1-1.5 parts of dibasic lead phthalate, 0.05-0.1 part of diphenol propane, 2-4 parts of Elvaloy 742, 1-3 parts of antimonous oxide, 0.1-0.5 part of chlorinated paraffin-52 and 0.3-0.5 part of ferrocene. The cable is resistant to oil and paint aging.
