Ultraviolet-proof seawater-corrosion-proof water-blocking loadable low-voltage cable for ships

Abstract

The invention discloses an ultraviolet-proof seawater-corrosion-proof water-blocking loadable low-voltage cable for ships. The cable comprises insulating wire cores, a rubber sleeve and an outer sheath layer, the rubber sleeve is arranged on the inner side of the outer sheath layer, and blocking plates which are parallel to one another are evenly arranged on the inner side of the rubber sleeve atequal intervals. According to the invention, hard limiting strips are arranged between the two adjacent insulating wire cores in the cable body; on one hand, two adjacent insulated wire cores are blocked by the limiting strips; abrasion between two adjacent insulated wire cores is avoided; mutual influence of heat among the insulating wire cores is avoided; on the other hand, the limiting strips are used, so that the end surfaces of the two adjacent limiting strips are propped against each other after the cable is extruded to generate slight deformation; the hard limiting strips are used as asupporting structure to bear extrusion force, the clamping groove is used for protecting the insulating wire cores, extrusion force borne by the insulating wire cores is reduced, and the hard limitingstrips are matched with the closed cavity and the blocking plates to improve the loading capacity of the cable.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to an ultraviolet-proof, seawater-corrosion-proof, water-resistance and load-bearing low-voltage cable for ships. Background technique [0002] With the development of science and technology in our country, earth-shaking changes have taken place in ship equipment, which are very widely used in military equipment. Our country has a vast sea area, in order to resist foreign aggression, we must have a large number of ships. After these ships go to sea When returning to the base for maintenance, it is necessary to perform magnetization and degaussing before entering the port. After degaussing, the ship needs to be repaired and maintained. At this time, an external power supply is required. The power supply cable includes low-voltage cables and medium-voltage cables. Smaller ships can use low-voltage cables. For power supply, due to the long distance between the ship and the power distrib...
