Anti-strong interference environment type signal measurement and control cable for ship safety monitoring system

technical field

The utility model relates to a cable structure, which belongs to the technical field of cables.

Background technique

The power lines and electrical control lines of large ships and warships need to use a large number of cables. Ships and warships sail in rivers and seas, and their power lines and electrical control lines are susceptible to high and low temperature, humidity, salt spray and other factors and external force collisions. Therefore, the outer braided armor layer of cables for ships and warships is beneficial to improve the performance and life of the cables. Existing ordinary cables composed of conductors, insulation, shielding layers, flame-retardant layers, water-blocking layers, and armor layers are used for power lines and electrical control lines of ships and warships, and cannot fully achieve anti-oxidation, anti-corrosion, and anti-corrosion. The effect of external impact cannot meet the requirements of accurate, safe and efficient operation of ships and military ships. The steel wire of the armor layer is easily corroded and damaged, which affects the service life of the cable.
