Abstract
The utility model relates to a special extrusion insulating power cable for an oil well, which is suitable for 1.14 kV voltage grade of oil wells in an oil field, is formed by a conductor, an insulating layer, a copper strip shielding layer, a filling material, an inner lining layer, a waterproof layer, an isolation sleeve, a steel strip armor, and an outer sheath, and is used for electric energy transmission of the 1.14 kV voltage grade of the oil wells in the oil field. The special extrusion insulating power cable for an oil well has the characteristics of shielding, waterproofing, anticorrosion, acid and alkali resistance, and anti-ant damage.
Description
Technical field
The utility model belongs to the cable technology field, is specifically related to the special-purpose extruded insulation power cable of a kind of 1.14kV oil well.
Background technology
The system of laying of field produces on-site cable generally adopts modes such as direct-burried, comb, raceway groove, tunnel, crane span structure, and cable maybe be local or immerse fully in the water during ponding in the raceway groove, and direct-burried cable when phreatic high maybe be often and periodically is immersed in water; Some areas subject to ant evil etc., destroy the insulation level of cable, reduce the cable voltage grade.
The used power cable of oilfield 1.14kV electric pressure was after reinforced insulation intensity on original lv power cable basis, to change a social system to form mostly in the past; Do not adopt suitable waterproof, shielding measure; In practical application, be prone to various faults such as insulation breakdown, and then influence the production efficiency and the production capacity of oil well.
Summary of the invention
In order to overcome the multiple shortcoming that exists in original oil well 1. 14kV electric pressure power cables design, the manufacturing; The purpose of the utility model provides a kind of oilfield 1.14kV electric pressure special electric power cable, and this cable can be applied to the oilfield production scene safely, efficiently.
The utility model has adopted following technical scheme for solving the problems of the technologies described above: the special-purpose extruded insulation power cable of said 1.14kV oil well is made up of conductor, insulating barrier, copper strips screen, packing material, inner covering, watertight composition, separation sleeve, steel-tape armouring, oversheath; Wherein said conductor is by stranded the forming of multiply single line hard copper conductor; Said insulating barrier is to be processed by the thermoset crosslink polyethylene insulating material, and the parcel conductor is peripheral; Said copper strips screen is the outer copper strips of one deck wrap insulate layer; Said packing material is to be made up of insulating material, is filled in the power cable between each phase heart yearn; Said inner covering is made up of insulating material, parcel copper strips screen and packing material; Said watertight composition is by the overlapping wrapped stop water of aluminium-plastic tape, the parcel inner covering; Said separation sleeve is the structure sheaf outside one deck parcel watertight composition, the parcel watertight composition; Said steel-tape armouring is processed by steel band, continuous, firm parcel separator; Said oversheath is to be processed by thermoplastic poly vinyl chloride composite material, the parcel steel-tape armouring.
Because the utility model has been taked technique scheme, compared with prior art, the utlity model has advantages such as waterproof, anticorrosion, acid and alkali-resistance, anti-ant evil; Can be applied to the oilfield production scene safely, efficiently.
Description of drawings
The architectural feature of the utility model is done the explanation in a step below in conjunction with accompanying drawing.
Fig. 1 is the utility model cross-sectional structure sketch map.
In the accompanying drawing: 1. conductor; 2. insulating barrier; 3. copper strips screen; 4. packing material; 5. inner covering; 6. watertight composition; 7. separation sleeve; 8. steel-tape armouring; 9. oversheath.
Embodiment
Referring to accompanying drawing, the special-purpose extruded insulation power cable of the said 1.14kV oil well of the utility model is made up of conductor 1, insulating barrier 2, copper strips screen 3, packing material 4, inner covering 5, watertight composition 6, separation sleeve 7, steel-tape armouring 8, oversheath 9; Said conductor 1 is the current path of power cable by stranded the forming of multiply single line hard copper conductor; The conductor global sections is long-pending to be decided by load current; Insulating barrier 2 is to be processed by the thermoset crosslink polyethylene insulating material, and parcel conductor 1 periphery is for conductor 1 provides reliable insulation property; Said copper strips screen 3 is that one deck is wrapped in the copper strips outside the insulating barrier 2; Conductor 1 outside radiated electromagnetic wave the time through alternating current; This electromagnetic wave can disturb other subscriber equipment and adjacent other phase line; For eliminating above-mentioned interference, use copper strips screen 3 to be wrapped in insulating barrier 2 peripheries, can be that each phase heart yearn provides well in the utility model, reliable shielding properties; Said packing material 4 is to be made up of insulating material, is filled between each phase heart yearn of the utility model, is the structural material of the utility model; Said inner covering 5 is made up of insulating material, and it act as with each phase heart yearn of the utility model and packing material parcel firmly, for subsequent handling is done the basis; Said watertight composition 6 is by the overlapping wrapped stop water of aluminium-plastic tape, is wrapped in outside the inner covering 5, and its effect is for the utility model excellent waterproofness to be provided.Said separation sleeve 7 is wrapped in the structure sheaf outside the watertight composition 6 for one deck, and its effect is with other interior structure sheaf isolation to be provided for watertight composition 6; Said steel-tape armouring 8 is processed by steel band, and continuous, the firm separator 7 that is wrapped in can be strengthened the structural strength of the utility model; Said oversheath 9 is to be processed by thermoplastic poly vinyl chloride composite material, has effects such as waterproof, anticorrosion, acid and alkali-resistance, anti-ant evil.
The environment that lays of the utility model is direct-burried, comb, raceway groove, tunnel, crane span structure etc.
