Description

Technical Field

[0001] This utility model specifically relates to the field of cable outer surface protection technology, and more specifically to a marine cable anti-salt spray protection device. Background Technology

[0002] Marine cables are a key transmission medium for power transmission on ships. As ships sail in the ocean environment for a long time, the chloride ions in the salt spray are highly corrosive and will react with metals electrochemically, destroying the oxide film on the metal surface and accelerating metal corrosion. Over time, the cross-sectional area of ​​the cable conductor decreases and the resistance increases, resulting in reduced power transmission efficiency. In severe cases, it may cause short circuits and affect the normal operation of ship equipment.

[0003] Currently, anti-salt spray coating for marine cables mainly adopts dipping or mechanical spraying methods, especially mechanical spraying, which is widely used. However, due to the variety of cable diameters, existing coating equipment is difficult to adapt to the coating requirements of cables of different diameters without changing the hardware, and the preparation work is quite cumbersome.
