Abstract
The invention discloses an oil-sludge-resistant cable which comprises a conductor, an inner sheath layer, an armor layer, an oil-resistant cushion layer and an outer sheath layer and is characterized in that a polyethylene insulating layer is arranged outside the conductor in an extruded mode to form cable cores, the two cable cores are twisted together and then wrapped in a polyester tape layer, the polyester tape layer is wrapped in the oil-resistant cushion layer to form insulation cable cores, the three insulation cable cores are combined and then wrapped in a polyester tape layer II, the inner sheath layer is arranged outside the polyester tape layer II, the metal steel tape armor layer is arranged outside the inner sheath layer, the armor layer is sequentially wrapped in an oil-resistant cushion layer II and the outer sheath layer, and a control cable core is further arranged at the position of the combination center of the three insulation cable cores. The oil-sludge-resistant cable is good in oil resistance and ozone resistance and capable of being adapted to the severe offshore oil platform working environment and the corrosivity of drilling fluid.
Description
technical field
The present invention relates to a kind of oil resistant mud cable, belong to technical field of electric wires and cables.
background technology
Along with the develop rapidly of Chinese national economy, energy demand improves constantly, and energy exploration seawater oil platform constantly increases, the fast development of energy device manufacturing industry.Marine environment is complicated and changeable, and ocean engineering is often wanted the strong effect of bearing typhoon (hurricane), wave, morning and evening tides, ocean current, ice slush etc., also will be subject to complex-terrain at the shallow water along the coast, and seashore develops, the impact of Sediment Transport.The Marine Environment Factors such as temperature, earthquake, radiation, electromagnetism, burn into biological attachment, also have impact to some ocean engineering.Therefore, while carrying out the external force analysis of building and works, consider the stochastic behaviour of various kinetic factors, in Structure Calculation, consider dynamic problem, in basic engineering, consider the ambiguity of periodic load action and soil, on material is selected, considering economy and durability etc., is all very necessary.Offshore engineering equipment is because of the particularity of its operating environment, supporting with it cable has been proposed to very high technical requirement, and conventionally cable for ocean engineering need to have the performances such as oil resistant, corrosion-resistant, high temperature resistant, low temperature resistant, wear-resisting, high mechanical properties, Halogen, low cigarette.
summary of the invention
The object of the invention is to provide a kind of oil resistant mud cable, has good oil resistant, ozone resistance, can adapt to the abominable of offshore oil platform operating environment and the corrosivity of boring liquid.
The solution of the present invention is as follows: a kind of oil resistant mud cable, comprise conductor, inner restrictive coating, armour, oil resistant bed course, external sheath layer, described conductor adopts zinc-plated soft copper tow strand to form, on described conductor, extrude polyethylene layer and form core, two stranded rear wrapped polyester belting layers of core, the outer wrapped oil resistant bed course of described polyester belting layer forms insulated wire cores, wrapped polyester belting layer II after three insulated wire cores combinations, described polyester belting layer II arranges inner restrictive coating outward, described inner restrictive coating arranges metallic steel band armour outward, described armour wraps up oil resistant bed course II and external sheath layer outward successively, three described insulated wire cores combination center places also arrange one control core, described control core by three lead the stranded rear wrapped polyester belting layer of core, inner covering forms.
Further, described inner restrictive coating and external sheath layer increase and adopt irradiation crosslinking halogen-free low cigarette polyolefin to extrude moulding.
Further, described armour adopts the steel band of 0.5mm to carry out lock armo.
In cable of the present invention, oversheath all adopts the low cigarette polyolefin jacket of irradiation crosslinking halogen-free of oil resistant mud, because the low cigarette polyolefin jacket of irradiation crosslinking halogen-free has the features such as good oil resistant, 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.Adopt the copper strips of 0.5mm to carry out lock armo, cable has high, the resistance to bending of mechanical strength, corrosion resistance and good, can resist the pressure in oil well, improves the oil resistance of cable, prevents that oil gas from entering insulating barrier.Be surrounded with oil resistant bed course at copper belt interlocking armored layer, improve the oil resistance of cable.
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 oil resistant mud cable, comprise conductor 1, inner restrictive coating 2, armour 3, oil resistant bed course 8, external sheath layer 5, described conductor 1 adopts zinc-plated soft copper tow strand to form, on described conductor 1, extrude polyethylene layer 6 and form core, two stranded rear wrapped polyester belting layers 7 of core, the outer wrapped oil resistant bed course 8 of described polyester belting layer 7 forms insulated wire cores, wrapped polyester belting layer II 9 after three insulated wire cores combinations, the outer inner restrictive coating 2 that arranges of described polyester belting layer II 9, described inner restrictive coating arranges metallic steel band armour 3 outward, outer oil resistant bed course II 4 and the external sheath layer 5 of wrapping up successively of described armour 3, three described insulated wire cores combination center places also arrange one control core 10, described control core by three lead the stranded rear wrapped polyester belting layer of core, inner covering forms.
Described inner restrictive coating 2 and external sheath layer 5 increase the low cigarette polyolefin of employing irradiation crosslinking halogen-free and extrude moulding.Described armour adopts the steel band of 0.5mm to carry out lock armo.
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.
