Description
Technical field:
The present invention relates to a kind of polar region oil well and move freely tired bending anti-interference control cable with anti-.
Background technology:
One, the exploitation in Arctic (so-called polar region refer to the earth north and south poles area) oil field in recent years, pumping unit of well must
Must use under the conditions of extremely harsh climate, for its supporting moving control cable due to do not adapt to operating temperature-60～
+ 125 DEG C and frequently move freely, cause cable to move freely bending and damage less than 15000 partial conductors fracture insulating sheaths, electricity
Cable continuous service life was less than 10 days.
Two, the subject matter existed:
1, in the construction of cable that design uses, insulation and sheath material do not adapt to the working temperature environment that polar region is severe, and cable
Architectural characteristic inadaptable move freely bending frequently.
2, in the construction of cable that design uses, conductor and cabling structure characteristic are not suitable with and move freely bending frequently.
3, cable anti-electromagnetic interference capability is poor, it is impossible to meets and uses requirement.
Summary of the invention:
For overcoming the defect of prior art, it is an object of the invention to provide a kind of polar region oil well and move freely tired bending with anti-
Anti-interference control cable, uses insulation and sheath material in the construction of cable to adapt to the working temperature environment that polar region is severe through on the spot,
And the architectural characteristic of cable adapts to move freely bending frequently.
The present invention solves technical problem and adopts the following technical scheme that
A kind of polar region oil well tired bends anti-interference control cable with anti-moving freely, arrange outside cable conductor stranding band around
Bag, is provided with total screen layer at described stranding band outer layer, and the outermost layer of cable is restrictive coating；
Described cable core is by many insulated wire cores twisted synthesizing cables, and each insulated wire cores is by conductor and extrudes in the vulcanite of conductor outer layer
Insulating barrier pair twist is constituted, and is surrounded with pair twist band at pair twist core outer layer, and described pair twist band outer layer is provided with sub-shield；
Described conductor uses many diameters to be not more than the beamline construction that the copper monofilament of 0.2mm is stranded, insulated wire cores twisted synthesizing cable
Direction of lay is identical with the copper monofilament direction of lay of conductor.
Described restrictive coating uses EPT rubber/thermoplastic cable jacket material to extrude formation.
Described total screen layer uses the plastic-aluminum combined wrapped and composite construction of proof copper-wire braided, total screen layer and described sub-shield shape
Become double layer screen Anti-interference cable structure.
Compared with the prior art, beneficial effects of the present invention is embodied in:
1, cable insulation of the present invention and the selection of jacket material, solves operating temperature-60～the problem of+125 DEG C, through reality
In the ground inspection construction of cable, insulation and sheath material adapt to the working temperature environment that polar region is severe, and the architectural characteristic of cable adapts to
Move freely bending frequently, owing to cable conductor uses many 0.2 and following copper monofilament with high density twisting pitch
Beamline construction, it is ensured that conductor bends flexible nature.Cable insulation core stranding stranded employing high density twisting pitch and stranded side
To identical with conductor strand direction, it is ensured that the bending flexible nature that cable core is overall so that cable moves freely Curved Continuous
Bent >=200000 times.
2, in the construction of cable that test design on the spot uses, conductor structure characteristic adaptation moves freely bending frequently.
3, the plastic-aluminum combined wrapped and composite construction of proof copper-wire braided, total screen layer is used to be formed with sub-shield due to total screen layer
Double layer screen Anti-interference cable structure so that cable anti-electromagnetic interference capability can meet use requirement.
4, the cable special manufacturing process processing method of checking fully meets the needs of batch production.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of cable of the present invention.
Label in figure: 1 conductor, 2 insulating barriers, 3 pair twist bands, 4 sub-shields, 5 stranding bands, 6 total screen layers, 7
Restrictive coating.
Below by way of detailed description of the invention, and the invention will be further described to combine accompanying drawing.
Detailed description of the invention:
Embodiment: combine Fig. 1, the cable of the present embodiment, it is wrapped that stranding band 5 is set, at stranding band 5 outside cable core
Outer layer is provided with total screen layer 6, and the outermost layer of cable is restrictive coating 7.
Cable conductor is by many insulated wire cores twisted synthesizing cables, and each insulated wire cores is by conductor 1 and extrudes the sulfuration rubber in conductor outer layer
Glue insulating barrier 2 pair twist is constituted, and is surrounded with pair twist band 3 at pair twist core outer layer, and pair twist band 3 outer layer is provided with sub-shield 4.
In specifically arranging, conductor 1 uses many diameters to be not more than the beamline construction that the copper monofilament of 0.2mm is stranded, it is ensured that conductor
