Longitudinal water-sealing degaussing cable and manufacturing process for same

Abstract

The invention discloses a longitudinal water-sealing degaussing cable. The longitudinal water-sealing degaussing cable is characterized by comprising three cores which are arranged in a delta shape or linearly. A plurality of tin plated copper wires are twisted to form a conductor in the center of each core of the cable by an electric wire and cable twisting machine. A waterproof adhesive is filled in gaps between every two of the plurality of tin plated copper wires. A first layer of wrapped waterproof tape is arranged on the periphery of the conductor. An insulating layer made of an insulating material ethylene propylene rubber is arranged on the periphery of the first layer of wrapped waterproof tape. A second layer of wrapped waterproof tape is arranged on the periphery of the insulating layer. A sheath is arranged on the periphery of the second layer of wrapped waterproof tape. The waterproof adhesive is filled in gaps between every two of the three cores which are arranged in the delta shape. The longitudinal water-sealing degaussing cable has the advantages that: by a multi-core structure, troubles in the multi-turn winding laying of the conventional single-core structure are avoided, and the longitudinal water-sealing degaussing cable is convenient to mount and lay; the longitudinal water-sealing degaussing cable can be used for compensating for own induced magnetic field of a naval ship, and is small in interference and good in degaussing effect, and a generated magnetic field is regular and easy to control; and the longitudinal water-sealing degaussing cable is low-smoke, halogen-free and low-toxicity.

Description

technical field [0001] The invention relates to a longitudinal watertight degaussing cable and a preparation process thereof; the cable spans two fields of the longitudinal watertight cable and the degaussing cable. Background technique [0002] The traditional degaussing cables are based on Russian technology. The conductor is extruded and insulated and then a sheath is added. It can also be simply regarded as a single power cable with a sheath. At present, the ship degaussing cables of domestic manufacturers mostly adopt this structure. This type of degaussing cable is mainly used in degaussing stations, degaussing ships, etc. for temporary degaussing. The present invention is specially used in the submarine degaussing system to eliminate the induced magnetic field, and has the longitudinal watertight performance of the cable, and there is no such product in the market at present. Contents of the invention [0003] The present invention proposes a longitudinal water-se...
