Abstract
The utility model discloses an armored cable used in ocean engineering, which comprises conductors and insulated wire cores, wherein each insulated wire core is formed by extruding a polyvinyl chloride insulating layer on each conductor; two insulated wire cores are stranded and then wrapped with a metal shielding layer to form a wire core group, four wire core groups are combined and then wrapped with a wrapping layer, a reinforcing layer woven by adopting nylon is arranged outside the wrapping layer, an outer sheath layer is extruded outside the reinforcing layer, and the outer sheath layer is extruded by adopting polyvinyl chloride; and conductive cores are arranged between the four wire core groups. According to the flexible cable used in ocean engineering, the conductors are reinforced by adopting nylon, the tensile strength of the cable is enhanced, the bending property of the cable is not affected, and the integral tension resistance of the cable is enhanced by adopting the nylon woven reinforcing layer; and the flexible cable used in ocean engineering is light in weight, has good flexibility and good bending performance, is convenient to manufacture, and is suitable to be used in parts which are moved and bent frequently and subjected to a certain tension. Nylon is non-toxic and light in weight, and has excellent mechanical strength, wear resistance and good corrosion resistance.
Description
technical field
The utility model relates to a kind of ocean engineering flexible electric cable, belongs to technical field of electric wires and cables.
background technology
In recent years, there is great historical variations in international energy market, international oil price continues to rise, record high repeatly, each side is in bearing immense pressure, turn one's attention to one after another the key areas of following world's oil resources---offshore oil, China has also been placed on an extremely important strategic location marine oil and gas industry.Through effort in recent years, the marine mining technology and equipment of enterprise of CNPC has all obtained significantly improving, and Chinese Sea oil exploitation really enters the large-scale development stage.When China's offshore oil output constantly rises, for successive years, extra large oily engineering main business income is rapid growth situation, and offshore oil service presents the situation that supply falls short of demand.Continuing to increase of China's marine petroleum development dynamics, for marine oil field service trade provides the wide market space, in this course, offshore oil platform is also just more and more obvious by the demand of fire prevention control and instrument cable, especially because cable itself has deadweight, in use often bending, As time goes on, cable very easily ruptures, and brings unnecessary impact to normal production.
Utility model content
The purpose of this utility model is to provide a kind of ocean engineering flexible electric cable, solves the problem that often occurs bending and torsion for ocean engineering for lowering or hoisting gear and mobile device cable.
Scheme of the present utility model is as follows: a kind of ocean engineering flexible electric cable, comprise conductor, insulated wire cores, and described conductor adopts multiply soft copper tow to be twisted into type, and described conductor extrudes polyvinyl chloride insulation layer outward and forms insulated wire cores; Two wrapped metal screen layers of insulated wire cores strand form core group, wrapped belting layer after four core group combinations, described belting layer arranges the reinforced layer that adopts knit nylon outward, and described reinforced layer extrudes external sheath layer outward, and described external sheath layer adopts polyvinyl chloride to extrude; Between four described core groups, also arrange and lead core, the described core of leading is made up of the wrapped polyvinyl chloride insulation layer of conductor.
Further, described conductor is twisted into type by 10-30 root soft copper tow, and described conductor cross sectional area is 10-80mm
2.
Further, in the middle of four described insulated wire cores, a nylon rope is also set.
The utility model cable conductor adopts nylon to strengthen, and has improved cable tensile strength, does not affect again the bending property of cable.Adopt knit nylon reinforced layer, thereby improved whole cable resistance to tension.The utility model cable is lightweight, and pliability is good, good bending property, easily manufactured.Often being suitable for mobile bending used by the place of certain pulling force.That nylon has is nontoxic, light weight, good mechanical strength, resistance to wear and corrosion resistance preferably.The utility model cable long service life, lightweight, and also cost is low, has good Social benefit and economic benefit.
brief description of the drawings
Fig. 1 is structural representation of the present utility model.
embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
A kind of ocean engineering flexible electric cable, comprises conductor, insulated wire cores, and described conductor 1 adopts multiply soft copper tow to be twisted into type, extrudes polyvinyl chloride insulation layer 2 and form insulated wire cores outside described conductor 1; Two wrapped metal screen layers 3 of insulated wire cores strand form core group, wrapped belting layer 4 after four core group combinations, the outer reinforced layer 5 that adopts knit nylon that arranges of described belting layer 4, described reinforced layer 5 is outer extrudes external sheath layer 6, and described external sheath layer 6 adopts polyvinyl chloride to extrude; Between four described core groups, also arrange and lead core 7, the described core 7 of leading is made up of the wrapped polyvinyl chloride insulation layer of conductor.
Described conductor 1 is twisted into type by 10-30 root soft copper tow, and described conductor 1 cross-sectional area is 10-80mm
2; In the middle of four described insulated wire cores, a nylon rope 8 is also set.
The utility model cable long service life, lightweight, and also cost is low, has good Social benefit and economic benefit.
Although above embodiment of the present utility model has been given to describe in detail and explanation; but what should indicate is; we can carry out various equivalences to above-mentioned execution mode according to conception of the present utility model and change and amendment; when its function producing does not exceed spiritual that specification and accompanying drawing contain yet, all should be within protection range of the present utility model.
