Abstract

The utility model provides a round cable for the electric oil-immersed pump and belongs to the technical field of cable. The cable structure includes a hinged conductor, an inner insulating layer, an external insulation layer, a protective sheath and an armor layer. The hinged conductor is formed by hinging and pressing 7 or 19 copper wires. The inner insulating layer is arranged on the outside of the hinged conductor, the external insulating layer is arranged on the outside of the inner insulating layer, and the inner and the external insulating layer and the hinged conductor form an independent signal transmission core. Three signal transmission cores of the same structure are sheathed by the protective sheath, the armor layer is arranged outside the protective sheath, and the external surface of the armor layer is in the shape of a continuous semicircle. Compared with prior art, the electric immersed pump round cable provided by the utility model has the advantages of resistance to high temperature, high current carrying amount, oil resistance, high resistance to corrosion, as well as capabilities for providing reliable electricity for high power electric pump and for maximumly inhibiting the underground matters from corroding the cable.

Description

Electric submersible pump electric power circle cable
(1) technical field
The utility model relates to a kind of cable, specifically a kind of electric submersible pump electric power of the supporting power supply of oil-immersed pump unit of the above high current-carrying capacity of 125A that is applicable to is justified the improving technology of armature of cable structure, be applicable to circular oil-submersible cable, can reduce cable and play the too fast armour skin dropout phenomenon that causes of well.
(2) background technology
At present, the oil-submersible cable of domestic use mostly is flat type cable.Domestic equipment manufacturer also can only provide the mould of producing flat type cable.Along with the increasing that country drops into oil development, heavy caliber oil well and marine oil field begin that oil-immersed pump circle cable is had very big demand.At present, there is ripe equipment can produce round cable abroad.But the producer that produces the circle cable with domestic equipment is few.And the product armour arc of producing is more flat, can not alternating bending, and thread off easily in the cable back of going into the well.
(3) summary of the invention
Technical assignment of the present utility model is at the deficiencies in the prior art, provides a kind of soft, and crooked back armour skin can restore, and is difficult for taking off mouth, can prolong the cable electric submersible pump electric power circle cable in useful life.
The technical scheme that its technical problem that solves the utility model adopts is:
This electric submersible pump electric power circle cable, comprise stranded conductor, inner insulating layer, external insulation layer, sheath and armour, the arranged outside of stranded conductor has inner insulating layer, the outside of inner insulating layer is provided with external insulation layer again, said structure is formed an independently signal transmission core, three identical signal transmission cores are coated by sheath, are provided with armour in the outside of sheath, and the outer surface of armour is continuous semicircular arc.Because sheath externally has than hightension, steel band edge and internal layer steel band overlap joint closely can effectively stop entering of the interior corrosive substance of oil well.
Above-mentioned electric submersible pump electric power circle cable, its stranded conductor is by 7 strands or 19 bursts of stranded forming of tinned wird.
Above-mentioned electric submersible pump electric power circle cable, the outer surface of its sheath is provided with the key tooth.
Electric submersible pump electric power circle cable of the present utility model compared with prior art, the beneficial effect that is produced is: the utlity model has high temperature resistant, high current-carrying capacity can be greater than 125 amperes, the advantage that oil resistant and corrosion resistance are strong, can be high-power electric pump reliable electric power is provided, control the corrosion of subsurface material to greatest extent cable.
(4) description of drawings
Accompanying drawing 1 is a cross section structure schematic diagram of the present utility model;
Accompanying drawing 2 is the structural representation after the utility model is cut armour open.
Among the figure, 1-stranded conductor, 2-inner insulating layer, 3-external insulation layer, 4-sheath, 5-armour, 6, the key tooth.
(5) embodiment
Below in conjunction with explaining below the round cable work of the novel electric submersible pump electric power of accompanying drawing 1,2 usefulness.
Embodiment 1:
As accompanying drawing 1,2, electric submersible pump electric power circle cable of the present utility model, its structure is by stranded conductor 1, inner insulating layer 2, external insulation layer 3, sheath 4 and armour constitute 5, stranded conductor 1 is by 7 bursts of stranded forming of tinned wird, the inner insulating layer 2 that the useful polyimide material of the arranged outside of stranded conductor 1 is made, the outside of inner insulating layer 2 is provided with the external insulation layer made from high-strength ternary second third glue 3 again, said structure is formed an independently signal transmission core, three sheath 4 coatings that identical signal transmission core is equilateral triangle and is made by high-strength ternary second third glue, the outer surface of sheath 4 is provided with key tooth 6, be provided with armour 5 in the outside of sheath 4, the outer surface of armour 5 is continuous semicircular arc.
Sheath appearance design and Flexible Design: jacket surface is designed to profile of tooth, and the about 1.5mm of tooth depth tightens up by armouring, reaches the purpose that increases sheath and steel band frictional force, thereby can prevent sheath and the landing mutually after being subjected to big pulling force of armour skin.The sheath material Intensity Design is for before aging: tensile strength 〉=12N/mm2, do ageing test by GB/T16750-1997 after, rate of change≤30%; Rate of change after the oil resistant test≤40%.The raising of sheath intensity makes sheath and armour skin form active force, guarantees the activity in the armour arc that armour skin barb can be stable.
The armour appearance design: the armour outward appearance is continuous semi arch profile, because sheath externally has than hightension, steel band edge and internal layer steel band overlap joint closely can effectively stop entering of the interior corrosive substance of oil well.
Embodiment 2:
In order to strengthen the pliability of electric submersible pump electric power circle cable, stranded conductor 1 also can be by 19 bursts of stranded forming of tinned wird, and other structures are constant.
