Abstract
The invention discloses an anti-aging cable which comprises conductors, insulating layers and sheath layers, wherein a cable core is formed by twisting of five insulation cable core bodies, the cable core is wrapped in an oil-resistant cushion layer, an inner sheath layer is arranged outside the oil-resistant cushion layer in an extruded mode, a metal braided armor layer is arranged on the inner sheath layer and is wrapped in a second oil-resistant cushion layer, an outer sheath layer is arranged outside the second oil-resistant cushion layer in an extruded mode, three conductive core bodies are twisted together and then wrapped in a lining layer and a metal shielding layer sequentially to form each insulation cable core body, each conductive core body is formed after the corresponding conductor is wrapped in the corresponding insulating layer, and a control cable core body is further arranged in the middle of the cable core. According to the anti-aging cable, both the inner sheath and the outer sheath are mud-resistant irradiation crosslinking halogen-free low-smoke polyolefin sheaths which are good in mud resistance and ozone resistance and high in mechanical strength, and therefore the service life of the cable can be prolonged.
Description
technical field
The present invention relates to a kind of ageing-resistant cable, belong to technical field of electric wires and cables.
background technology
The cable that offshore oil platform is used is now substantially all take shipboard cable as main, because common shipboard cable does not have mud property.For offshore oil platform, especially all kinds of production platforms, because of the abominable of its operating environment and the corrosivity of boring liquid, for guaranteeing equipment serviceability and safety, increase the service life, and cable must have resistance to mud property.The probing of drilling platforms, because of its frequent all kinds of brill liquid of contact, easily causes that cable is aging, and then shortens cable useful life.
summary of the invention
The object of the invention is to provide a kind of resistance to mud, resistance to ozone, ageing-resistant cable.
The solution of the present invention is as follows: a kind of ageing-resistant cable, comprise conductor, insulating barrier, restrictive coating, cable core is by five stranded forming of insulated wire cores, the outer wrapped oil resistant bed course of described cable core, on described oil resistant bed course, adopt the low cigarette of the irradiation crosslinking halogen-free polyolefin of resistance to mud to extrude inner restrictive coating, described inside and outside jacket layer is provided with metal knitted armour, and wrapped the second oil resistant bed course again on armour, is extruded with external sheath layer on the second described oil resistant bed course; Described insulated wire cores by three lead core stranded after successively wrapping lining-layer, metal screen layer form, the described core of leading is made up of the outer wrapped cross-linked polyolefin insulating barrier of conductor; Described cable core middle part is also provided with control core, and described control core is led the outer wrapped cross-linked polyolefin insulating barrier of core by two and formed.
Further, described conductor is by stranded the forming of 10-40 root silver-gilt copper wire.
Further, described metallic shield layer thickness is 0.5-5mm.
In cable of the present invention, oversheath all adopts the low cigarette polyolefin jacket of irradiation crosslinking halogen-free of resistance to mud, because the low cigarette polyolefin jacket of irradiation crosslinking halogen-free of resistance to mud has the features such as good resistance to mud, resistance to ozone, high mechanical properties.Be well suited for for the abominable of offshore oil platform operating environment and the corrosivity of boring liquid, extend cable useful life.Cable long service life of the present invention, and cost is low, has good Social benefit and economic benefit.
Accompanying drawing explanation
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 ageing-resistant cable, comprise conductor 1, insulating barrier 2, restrictive coating, cable core is by five stranded forming of insulated wire cores, the outer wrapped oil resistant bed course 5 of described cable core, on described oil resistant bed course 5, adopt the low cigarette of the irradiation crosslinking halogen-free polyolefin of resistance to mud to extrude inner restrictive coating 6, described inside and outside jacket layer 6 is provided with metal knitted armour 7, and wrapped the second oil resistant bed course 8 again on armour 7, is extruded with external sheath layer 9 on the second described oil resistant bed course 8; Described insulated wire cores by three lead core stranded after successively wrapping lining-layer 3, metal screen layer 4 form, the described core of leading is made up of the outer wrapped cross-linked polyolefin insulating barrier 2 of conductor 1; Described cable core middle part is also provided with controls core 10, and described control core is led the outer wrapped cross-linked polyolefin insulating barrier of core by two and formed.
Described conductor 1 is by stranded the forming of 10-40 root silver-gilt copper wire, and described metal screen layer 4 thickness are 0.5-5mm.
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 revise; 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.
Claims (3)
