A watertight mooring detection cable and a manufacturing process thereof

Abstract

The invention provides a watertight mooring detection cable. The watertight mooring detection cable comprises annealed copper wire conductors. Conductors are externally provided with crosslinked polyethylene insulation layers through extrusion and thus power wire insulation wire cores are formed. Conductors are externally provided with low-density polyethylene insulation layers through extrusion and thus signal wire insulation wire cores are formed. Two strands of the signal wire insulation wire cores form an insulation wire core group I through pair twisting. Three insulation wire core groups and three power wire insulation wire cores are twisted to form a cable core. A water-blocking wrapping layer, a water-blocking adhesive layer, a copper-plastic composite belt shield layer, a water-blocking aramid fiber layer, a thin non-woven cloth layer, a water-blocking aramid fiber layer I, and a flame-retardant polyurethane outer sheath are arranged on and wrapped around the outer side of the cable core successively. The invention also provides a production method of the cable. According to the invention, the problems of insufficient longitudinal watertightness and poor breaking force resistance of cables are solved, and the cable has excellent watertightness and tensile load-bearing capability, can maintain the reliability of power transmission and data signal transmission normally under certain water pressure and has certain tensile strength.
