Longitudinal watertight degaussing cable for ships

Abstract

The invention discloses a longitudinal watertight degaussing cable for ships, which comprises three tinned copper conductors, the outer sides of the three tinned copper conductors are all coated withethylene propylene rubber insulating layers, the three tinned copper conductors are arranged in an abutting manner, and gaps among the ethylene propylene rubber insulating layers of the three tinned copper conductors are filled with filling material strips. The three ethylene propylene rubber insulating layers are wrapped in the first sealant layer, and a plurality of connecting clamping grooves distributed at equal intervals are formed in the outer wall of the first sealant layer. Chlorosulfonated polyethylene inner sheaths are connected to the two sides of the first sealant layer in a clamped mode, and a plurality of connecting strips are fixedly connected to the inner walls of the two chlorosulfonated polyethylene inner sheaths. The longitudinal watertight degaussing cable is strong inthe wholeability to work under pressure, better adaptability to external force such as stretching and twisting in the actual use process is achieved, and meanwhile good water tightness is achieved.

Description

technical field [0001] The invention relates to the field of cable equipment, in particular to a longitudinal watertight degaussing cable for ships. Background technique [0002] Ship degaussing technology is a technology that the navies of various countries must master and commonly use to prevent damage from weapons in waterproofing. The degaussing operation is to remove the residual magnetic field on the metal shell of the ship, so as not to be detected by other submarines and surface ships during operation. Moreover, degaussing also protects troops from magnetically fuzed mines. The ship degaussing device is a device used to counteract or compensate the ship's magnetism and magnetic field. The degaussing cable is an important part of the ship's degaussing device. [0003] The structure of the existing degaussing cables is relatively simple. During long-term use, the outer layer of the cable will often be damaged due to external force extrusion. Since the ethylene-propyl...

Problems solved by technology

[0003] The structure of the existing degaussing cables is relatively simple. During long-term use, external force extrusion and other effects often occur to damage the outer layer of the cable. Since the ethylene-propylene insulating material commonly used in degaussing cables has strong hygroscopicity, when the sheath is damaged, water flow It directly enters the inside of the cable, affecting the insulation performance of the cable, making it unusable. At the same time, it is used for the inevitable stretching and twisting of the cable during use. Long-term reciprocating stretching and twisting will easily cause the inner core of the cable to break or move. bit, affecting cable use
