Embodiment 1

[0021] Such as figure 1 As shown, the whitening and anti-ultraviolet marine overall shielded instrument cable of the present invention is manufactured according to the following steps: extruding and whitening and anti-ultraviolet ethylene-propylene rubber insulating layer 2 on the outer periphery of a tinned annealed stranded copper conductor 1 of 0.35 mm to form an insulating core , the insulated wire cores are twisted in pairs to form a pair of twisted wires, the twisted pitch of each pair of twisted wires is not greater than 120mm and all pairs of twisted wires use different twisted pitches; all pairs of twisted wires The cable core is formed by right-hand stranding with a twisting pitch ratio of 16 to 24 times. The outer circumference of the cable core is wrapped with a copper foil polyester composite tape shielding layer 3 and the copper foil faces inward. The copper foil polyester composite tape shielding layer The inner side is provided with a tinned stranded copper wir...

Embodiment 2

[0027] The whitening and anti-ultraviolet marine overall shielding instrument cable of the present invention is manufactured according to the following steps: extrude and pack the whitening and anti-ultraviolet ethylene-propylene rubber insulation layer 2 on the outer periphery of a tinned annealed stranded copper conductor 1 of 1.25 mm to form an insulating core, and an insulating wire The cores are twisted in pairs to form a pair of twisted wires. The twisted pitch of each pair of twisted wires is not greater than 120mm and all pairs of twisted wires adopt different twisted pitches; 24 times the stranded pitch ratio than right-hand twisted to form a cable core, the outer periphery of the cable core is wrapped with a copper foil polyester composite tape shielding layer 3 and the copper foil faces inward, and the inner side of the copper foil polyester composite tape shielding layer is set Tinned stranded copper wire drain wire 3a, tinned stranded copper wire drain wire 3a runs...

Abstract

The invention relates to a marine integral 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, the all stranded wire pairs are stranded rightwards according to the 16-24 times of stranded node ratio to form a cable core, a copper foil polyester composite belt screening layer is lapped at the periphery of the cable core, a copper foil surface is inward, a tin-plating stranded steel drainage wire is arranged on the inner side of the copper foil polyester composite belt screening layer, penetrates through the full length of each stranded pair and clings together with the copper foil surface; and a polyester belt is lapped at the periphery of the copper foil polyester composite belt screening layer, an inner protecting bush is extruded at the periphery of the polyester belt, 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 integral 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 an overall shielded instrument cable for whitening and anti-ultraviolet ships. The invention also relates to a method for manufacturing a whitening and anti-ultraviolet marine overall shielding 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 mark...
