Abstract

The invention relates to a whitening ultraviolet-proof double-shield instrument cable for ships and a manufacturing method thereof. The cable is characterized in that a whitening ultraviolet-proof ethylene-propylene rubber insulation layer is extruded at the periphery of a tin-plated annealed stranded copper conductor to form an insulation wire core; every two insulation wire cores are twisted to form twisted wire pairs; each twisted wire pair is wrapped with a wire core copper foil polyester composite tape shielding layer at the periphery; the wire core copper foil polyester composite tape shielding layers are each wrapped with a wire core polyester tape at the periphery to form a pair-twist group; all the pair-twist groups are stranded to the right at 16-24 times of stranding lay ratio to form a cable core; the cable core is wrapped with a cable core copper foil polyester composite tape shielding layer at the periphery; the cable core copper foil polyester composite tape shielding layer is wrapped with a cable core polyester tape at the periphery; an inner sheath is extruded at the periphery of the cable core polyester tape; the inner sheath is coated with a copper alloy wire weaving armor layer at the periphery; and an outer sheath is extruded at the periphery of the copper alloy wire weaving armor layer. The insulation layer of the double-shield cable is white in color, good in mechanical property, excellent in anti-ultraviolet irradiation and anti-aging performance, and long in service life.

Description

technical field [0001] The invention relates to an instrument cable, in particular to a whitening and anti-ultraviolet marine double-shielded instrument cable. The invention also relates to a method for manufacturing a whitened and anti-ultraviolet-proof marine double-shielded instrument cable. 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 of markin...
