Abstract

The invention discloses a corrosion proof cable used for an offshore oil platform. The corrosion proof cable comprise conductors, insulation cable cores and a sheath layer, wherein insulation layers respectively wrap the outer sides of the conductors to form cable cores; three cable cores are twisted and then are wrapped by aluminium wrapping belts to form the insulation cable cores; five insulation cable cores are combined and are wrapped by a copper wire braiding lining layer; an insulation cable core II of which a conductor is wrapped by an insulation layer is also arranged in the middle of the combination of the five insulation cable cores; a zinc-coated wire armor layer wraps the outer side of the lining layer; an inflaming retarding zero halogen anti-corrosion mud polyolefin sheath wraps the outer side of the armor layer. According to the cable, five insulation cable cores are arrayed, the superposition of electromagnetic waves of a variable frequency cable is reduced; the shielding layer is formed by copper wire braiding, the anti-interference characteristic is good, the armor layer adopts thick zinc-coated wire armoring, the mechanical injury can be prevented, and the corrosion and the embrittlement of the steel wire are effectively prevented by smearing pitch.

Description

A kind of offshore oil platform corrosion proof cable
Technical field
The present invention relates to cable industry, be specifically related to a kind of offshore oil platform corrosion proof cable.
 
Background technology
Cable is normally by the cable of several or at least two every group stranded similar ropes that form of several groups of wires, mutually insulated between every group of wire, and be often twisted into round Yi Gen center, whole outside is surrounded by the cover layer of high-insulation.Cable has power cable, control cables, compensating cable, shielded type cable, high-temperature cable, computer cable, signal cable, coaxial cable, fire-resisting cable, shipboard cable, aluminium alloy cable etc.They are all made up of sub-thread or stranded conductor and insulating barrier, are used for connecting circuit, electrical equipment etc.
Traditional cable for petroleum flat is a topic being difficult to resolve for the corrosion-resistant of seawater in actual working environment always.
Summary of the invention
The invention provides a kind of offshore oil platform corrosion proof cable, meet ocean engineering cable and have low cigarette, Halogen, the performance index such as fire-retardant, this cable has also solved corrosion-resistant, resistance to mud problem simultaneously.
The solution of the present invention is as follows: a kind of offshore oil platform corrosion proof cable, comprise conductor, insulated wire cores and restrictive coating, and described conductor outside is enclosed with respectively insulating barrier and forms core, and three stranded rear wrapped aluminum belting layers of core form insulated wire cores; The inner covering of wrapped employing proof copper-wire braided after five insulated wire cores combinations, the combination middle part of five described insulated wire cores is also provided with the insulated wire cores II of a conductor wrap insulate layer; Described inner covering outside is enclosed with zinc-coated wire armour, and described armour outside is enclosed with the corrosion-resistant mud polyolefin jacket of fire-retardant Halogen layer.
Further, to amass be 15~100mm to described cross-sectional area of conductor 2.
Further, described armour outside is coated with bitumen layer.
Cable core of the present invention adopts five insulated wire cores to arrange, and has reduced the electromagnetic stack of frequency-changing cable; Screen adopts proof copper-wire braided to form, and anti-tampering characteristic can be good, and armour adopts lagging cover zinc wire armoring, can prevent mechanical damage characteristic, smear pitch and effectively prevent the corrosion-resistant and embrittlement of seawater to steel wire, with flame-proof cross-linking polyolefine material be insulation, there is good fire resistance.
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 offshore oil platform corrosion proof cable, comprises conductor 1, insulated wire cores and restrictive coating, and described conductor 1 outside is enclosed with respectively insulating barrier 2 and forms core, and three stranded rear wrapped aluminum belting layers 3 of core form insulated wire cores; The inner covering 4 of wrapped employing proof copper-wire braided after five insulated wire cores combinations, the combination middle part of five described insulated wire cores is also provided with the insulated wire cores II 5 of a conductor wrap insulate layer; Described inner covering 4 outsides are enclosed with zinc-coated wire armour 6, and described armour 6 outsides are enclosed with the corrosion-resistant mud polyolefin jacket of fire-retardant Halogen layer 7.
Further, described conductor 1 sectional area is 15~100mm 2, described armour 6 outsides are coated with bitumen layer.
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.
