Abstract
The invention discloses a flexibility control cable for ocean engineering. Conductors are molded by bundling and intertwisting a plurality of soft copper wires, a polyvinyl chloride insulating layer is extruded on each conductor to form an insulated wire core, and plurality of insulated wire cores are intertwisted and wrapped by a polyester belting layer; the belting layer is externally provided with a reinforced layer braided by nylon, an outer sheath layer is extruded outside the reinforced layer, and the outer sheath layer is extruded by using polyvinyl chloride. The cable in the invention has a long service life and light weight, is low in cost, and has good social benefits and economic benefits.
Description
Technical field
The present invention relates to a kind of cable, particularly ocean engineering pliability control cables, belong 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, ocean engineering is also just more and more obvious by the demand of pliability control cables, 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.
Summary of the invention
The object of this invention is to provide a kind of ocean engineering pliability control cables, solve the problem that often occurs bending and torsion for ocean engineering for lowering or hoisting gear and mobile device cable.
The solution of the present invention is as follows: a kind of ocean engineering pliability control cables, and its conductor adopts multiply soft copper tow to be twisted into type, extrudes polyvinyl chloride insulation layer and forms insulated wire cores, the stranded and wrapped polyester belting layer of split conductor core on described conductor; Described belting layer arranges the reinforced layer that adopts knit nylon outward, and described reinforced layer extrudes external sheath layer outward, and described jacket layer adopts polyvinyl chloride to extrude.
Described insulated wire cores is 4-7 thigh.
Beneficial effect of the present invention:
1, cable conductor of the present invention adopts nylon to strengthen, and prevents nylon reinforcing element at cable conductor Shu Jiaoshi center, has improved cable tensile strength, does not affect again the bending property of cable.
2, cable of the present invention adopts knit nylon reinforced layer, thereby has improved whole cable resistance to tension.
3, cable of the present invention 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.
4,, reinforcing element of the present invention and braiding all adopt nylon, that nylon has is nontoxic, light weight, good mechanical strength, resistance to wear and corrosion resistance preferably.
5, cable long service life of the present invention, lightweight, and cost is low, has good Social benefit and economic benefit.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described.
A kind of ocean engineering pliability control cables, its conductor 1 adopts multiply soft copper tow to be twisted into type, extrudes polyvinyl chloride insulation layer 2 and forms insulated wire cores, the stranded and wrapped polyester belting layer 3 of split conductor core on described conductor 1; The outer reinforced layer 4 that adopts knit nylon that arranges of described belting layer 3, described reinforced layer extrudes external sheath layer 5 outward, and described jacket layer 5 adopts polyvinyl chloride to extrude.
Described insulated wire cores is 4-7 thigh.
Cable provided by the invention 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.
Although above the specific embodiment of the present invention 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 invention and change and amendment; when its function producing does not exceed spiritual that specification and accompanying drawing contain yet, all should be within protection scope of the present invention.
