Background technology:
One, the exploitation in oil field, Arctic (so-called polar region refers to earth north and south poles area) in recent years, pumping unit of well must extremely use under harsh climate condition, for its supporting moving control cable is owing to can not adapting to working temperature-60～+ 125 DEG C and frequently moving freely, cause cable to move freely bending less than 15000 partial conductor fracture insulating sleeves and damage, cable less than in continuous useful life 10 days.
Two, the subject matter existing:
1, in the construction of cable that design is used, insulation and sheath material can not adapt to the severe working temperature environment in polar region, and the architectural characteristic of cable is inadaptable moves freely frequently bending.
2, in the construction of cable that design is used, conductor and cabling structure characteristic are not suitable with and move freely frequently bending.
3, cable anti-electromagnetic interference capability is poor, can not meet instructions for use.
Summary of the invention:
For overcoming the defect of prior art, the purpose of this utility model is to provide a kind of polar region oil well to move freely tired bending antidisturbance control cable with resisting, use the severe working temperature environment of insulation and sheath material adaptation polar region in the construction of cable through on the spot, and the architectural characteristic of cable adapts to move freely frequently bending.
The utility model technical solution problem adopts following technical scheme:
A kind of polar region oil well moves freely tired bending antidisturbance control cable with anti-, and cable conductor outer setting stranding band is wrapped, is provided with total screen at described stranding band skin, 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 made up of with extruding in the outer field vulcanized rubber insulating barrier of conductor pair twist conductor, is surrounded with pair twist band at pair twist core skin, and described pair twist band skin is provided with sub-shield;
Described conductor adopts the many stranded bunch structures of copper monofilament that diameter is not more than 0.2mm, and the direction of lay of insulated wire cores twisted synthesizing cable is identical with the copper monofilament direction of lay of conductor.
Described restrictive coating adopts EPT rubber/thermoplastic cable jacket material to extrude formation.
Described total screen adopts the composite construction of plastic-aluminum combined wrapped and proof copper-wire braided, total screen and described sub-shield formation double layer screen Anti-interference cable structure.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
1, selecting of the utility model cable insulation and jacket material, solve the problem of working temperature-60～+ 125 DEG C, check the severe working temperature environment of insulation and sheath material adaptation polar region in the construction of cable through on the spot, and the architectural characteristic of cable adapts to move freely frequently bending, be because cable conductor adopts many 0.2 ㎜ and following copper monofilament with the bunch structure of high density twisting pitch, ensure the bending flexible nature of conductor.Cable insulation core stranding stranded employing high density twisting pitch and direction of lay are identical with conductor direction of lay, have ensured the bending flexible nature of cable core entirety, make cable move freely continuous bend >=200000 time.
2, in the construction of cable that test design uses on the spot, conductor structure characteristic adaptation moves freely bending frequently.
3, the composite construction that adopts plastic-aluminum combined wrapped and proof copper-wire braided due to total screen, total screen and sub-shield formation double layer screen Anti-interference cable structure, make cable anti-electromagnetic interference capability can meet instructions for use.
4, the special manufacturing process processing method of cable of checking meets the needs of batch production completely.
