Abstract
Disclosed in the utility model is an anti-oil sludge cable comprising conductors, an inner sheath layer, an armored layer, an anti-oil gasket layer, and an outer sheath layer. The cable is characterized in that the conductors are respectively wrapped by a polyethylene insulating layer in an extrusion manner to form wire cores; each two wire cores are stranded and then are wrapped with one polyester wrapping tape layer; the polyester grid layers are wrapped with the anti-oil gasket layers to form insulated wire cores; and the three insulated wire cores are combined and then are wrapped with a polyester wrapping tape layer II. The inner sheath layer is arranged outside the polyester grid layer II; a metal steel belt armored layer is arranged outside the inner sheath layer; and an anti-oil gasket layer II and the outer sheath layer successively coat the armored layer. Besides, a control wire core is arranged in the center of the combination of the three insulated wire cores. The provided cable with good oil-proof and ozone-proof performances an can adapt to seriousness of the working environment of the offshore oil platform and be resistant to corrosivity of the drilling fluid.
Description
technical field
The utility model relates to a kind of oil resistant mud cable, belongs 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., at the shallow water along the coast, also will be subject to complex-terrain, 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 specification 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.
utility model content
The utility model object 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.
Scheme of the present utility model 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 and 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 the low cigarette polyolefin of irradiation crosslinking halogen-free to extrude moulding.
Further, described armour adopts the steel band of 0.5mm to carry out lock armo.
In the utility model cable, 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.At copper belt interlocking armored layer, be surrounded with oil resistant bed course, improve the oil resistance of cable.
accompanying drawing explanation
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 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 and 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 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 revise; 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.
