Novel salt spray resistant cable

Abstract

The invention provides a novel salt spray resistant cable. The novel salt spray resistant cable comprises a conductor, an insulating layer, an inner sheath and a salt spray resistant outer sheath. Thenovel salt spray resistant cable effectively improves overall salt spray resistant performances of the cable, and the salt spray resistant outer sheath is arranged, and the formula of the salt sprayresistant outer sheath developed through scientific researches and multiple tests comprises silicone rubber, diphenyl silicon glycol, antimony trioxide, epoxy resin, potassium silicate, high temperature resistant composite powder, mica powder, an organic solvent, rapeseed oil, an anti-UV agent and nano-metallic oxide, therefore, the prepared salt spray resistant outer sheath has the excellent saltspray resistant function. In the using process, the rapeseed oil is gradually precipitated on the surface of the salt spray resistant outer sheath to effectively prevent crystal salt caused by seawater from adhering to the surface of the cable, so that the cable can be better protected, and then the service life of the cable can be greatly improved.

Description

technical field [0001] The invention belongs to the technical field of electric cables, and in particular relates to a novel anti-salt spray electric cable. Background technique [0002] Salt-spray resistant cables are used for power connections on marine exploration vessels and oil rigs. The cable floats on the water surface through the buoy, and transmits power to the mining equipment. In such an application, it often has to withstand high wind speed, strong ultraviolet radiation, high salt pollution, brine immersion, and severe acid, alkali, oil, and salt corrosion. After a long-term use of ordinary cables, a thick layer of crystalline salt will condense on the surface of the cable, increasing the weight of the cable, resulting in an increase in the weight of the cable, corroding the surface of the cable, and in severe cases, the cable will be broken. This situation is difficult. There has been no good solution to the problems that have plagued users and cable manufactur...

Problems solved by technology

The cable floats on the water surface through the buoy, and transmits power to the mining equipment. In such an application, it often has to withstand high wind speed, strong ultraviolet radiation, high salt pollution, brine immersion, and severe acid, alkali, oil, and salt corrosion. After a long-term use of ordinary cables, a thick layer of crystalline salt will condense on the surface of the cable, increasing the weight of the cable, resulting in an increase in the weight of the cable, corroding the surface of the cable, and in severe cases, the cable will be broken. This situation is difficult. For many years, there has been no good solution to the problems of users and cable manufacturers, so that users have to remove the crystallized salt on the surface of the cable every six months, and replace the cable once a year.
