Strong-current signal composite cable for submarine and production method thereof

Abstract

The invention discloses a strong-current signal composite cable for a submarine. The strong-current signal composite cable comprises a signal wire core group I, a signal wire core group II and strong-current insulated wire cores, wherein the signal wire core group I, the signal wire group II and the four strong-current insulated shielding wire cores are stranded into a cable core; and a wrapping water-blocking wrapping tape layer, a water-blocking aramid fiber layer and a polyurethane outer sheath are sequentially arranged outside the cable core. The invention further discloses a production method of the strong-current signal composite cable for the submarine. The strong-current signal composite cable for the submarine provided by the invention successfully solves the problems of insufficient longitudinal water tightness and insufficient anti-movement tension of a common underwater cable, so that the cable is enabled to keep stable reliability of normal power transmission and digital signal transmission under a certain water pressure condition and in a naval vessel sailing process, has comprehensive functions of power transmission, instruction transmission, digital signal transmission and the like, and has high bending characteristic, excellent corrosion resistance, abrasion resistance and repeated winding and unwinding capacity.
