Abstract

The invention relates to a marine independent screening instrument cable capable of whitening and resisting ultraviolet and a manufacturing method thereof. Whitening and ultraviolet-resisting ethylene propylene rubber insulation layers are extruded at the peripheries of tin-plating annealing stranded copper conductors to form insulation wire cores, every two insulation wire cores are stranded to form a stranded wire pair, a copper foil polyester composite belt screening layer is lapped at the periphery of each group of stranded wire pair, copper foil surfaces are inward, tin-plating stranded steel drainage wires are arranged on the inner sides of the copper foil polyester composite belt screening layers, penetrate through the full length of each stranded pair and cling together with the copper foil surfaces; and a polyester belt is lapped at the periphery of each copper foil polyester composite belt screening layer to form a stranded group; and the all stranded groups are stranded rightwards according to the 16-24 times of stranded node ratio to form a cable core, an inner protecting bush is extruded at the periphery of the cable core, a copper alloy wire knitting armor layer covers the periphery of the inner protecting bush, and an outer protecting bush is extruded at the periphery of the copper alloy wire knitting armor layer. The independent screening instrument cable has the advantages that the color of an insulation layer is white, the mechanical property is good, the performance of resisting aging caused by ultraviolet light is excellent, and the service life is long.

Description

technical field [0001] The invention relates to an instrument cable, in particular to a whitening and ultraviolet-proof marine independent shielding instrument cable. The invention also relates to a manufacturing method of an independent shielded instrument cable for whitening and anti-ultraviolet ships. Background technique [0002] With the serious situation of shipbuilding, everyone pays more attention to cost control, and has higher requirements on the performance and service life of various supporting equipment. Marine cables often need to withstand sunlight exposure during the day and high-power lamps and lanterns at night. The ultraviolet radiation they suffer will accelerate aging, reduce insulation performance, and affect the safety and life of use. Often the service life of the cable is shorter than the design of the ship. life, affecting the use of ships. At the same time, since marine cables generally use printing numbers on the insulating surface as the method...
