Abstract
The utility model discloses a power cable special for an oil well. The power cable is characterized in that conductors employ tinned soft copper wires; an insulated wire core is formed by extruding ethylene/propylene copolymer on each conductor; a plurality of insulated wire cores and soft filling ropes are stranded, cabled, and bound by a winding tape to form a cable core; a liner layer, an armored layer and an outer jacket layer are sequentially arranged on an outer layer of the cable core; the liner layer and the outer jacket layer are respectively formed by extrusion; and the armored layer is formed by weaving metal wires and fiber wires. The power cable special for the oil well has the characteristics of softness, high/low temperature resistance, oil resistance, moisture resistance, mechanical impact resistance and the like, is applicable to working environment and light in weight, and can serve as an electrical connection line in the occasions such as oil well drilling, an oil platform and a port.
Description
Technical field
The utility model relates to a kind of power cable, relates in particular to a kind of oil well specialized power cable, belongs to technical field of electric wires and cables.
Background technology
The cable that most oil exploitation platforms are used in the prior art, its structure and shipboard cable are similar, take synthetic rubber (such as ethylene propylene diene rubber) as insulation, take heat-resisting, oil resistant, fire proofing (such as HOFR) as sheath.In order to strengthen mechanical protection and electic protection, usually make armouring with the zinc-coated wire of braiding.Although the cable of this version has good mechanical electric performance and anti-flammability, exist the cable flexibility not ideal enough, the problem that the protective coverings of cable mechanical strength is not high enough.
Summary of the invention
The utility model is for avoiding the existing weak point of above-mentioned prior art, a kind of oil well specialized power cable is provided, the good characteristic that not only has high temperature resistant, low temperature resistant, oil resistant, humidity and anti-mechanical shock, and lightweight and soft, in the hope of meeting the corresponding instructions for uses in place such as oil well probing, oil platform, harbour.
The utility model is that the technical solution problem adopts following technical scheme:
The design feature of the utility model oil well specialized power cable is that conductor adopts zinc-plated soft copper silk, extrude ethylene-propylene rubber at described conductor and consist of insulated wire cores, consist of cable core by many eradications edge core and soft type gasket for packing twisted synthesizing cable and through the band wrapping, set gradually the armour that the inner covering, knit wire and the filament that extrude formation consists of at the skin of described cable core, and the external sheath layer that extrudes formation.
The design feature of the utility model oil well specialized power cable also is:
Described conductor adopts tin-coated copper tow strand, a burst strand circle to press structure.
Described soft type gasket for packing is to adopt the fibrage rope.
Described armour is that zinc-coated wire is identical by number of spindles with Polyamide Yarns, the opposite direction braiding forms.
It is that raw material extrudes and forms that described inner covering and external sheath layer adopt flame-retardant polyurethane thermoplastic elastomer (TPE) or chlorosulfonated polyethylene.
Compared with the prior art, the utility model beneficial effect is embodied in:
1, high temperature resistant, low temperature resistant, the oil resistant of cable of the present invention, humidity, anti-mechanical shock, it is lightweight and soft, can meet the corresponding instructions for uses in place such as oil well probing, oil platform, harbour.
2, tin-coated copper tow strand, a burst strand circle are pressed structure in the utility model, press drawing process by employing, more improved the cable flexibility, have reduced the outside dimension of cable;
3, the utility model is filled with the fibrage rope, by the fibrage rope that adopts high strength, super soft, light specific gravity, do not absorb water, more improves the endwise tensile strength of cable;
4, the utility model armour has adopted the braiding of zinc-coated wire and Polyamide Yarns to form, and has both played the metallic shield effect, has also improved the shock resistance of cable, the performance of anti-extrusion and anti-mechanical pulling force, has more improved the flexibility of cable simultaneously;
5, the utility model inner covering and external sheath layer are take flame-retardant polyurethane thermoplastic elastomer (TPE) or chlorosulfonated polyethylene as material, and its intensity is high, percentage elongation is large, and oil resistance is excellent, easy to process, and have excellent resistance to low temperature.
Description of drawings
Fig. 1 is the utility model structural representation.
Number in the figure: 1 conductor, 2 insulated wire cores, 3 gasket for packings, 4 bands, 5 inner coverings, 6 armours, 7 external sheath layers.
Embodiment
Referring to Fig. 1, it is four-core oil well specialized power cable in the present embodiment, conductor 1 adopts zinc-plated soft copper silk, extrude the ethylene-propylene rubber material at conductor 1 and consist of insulated wire cores 2, consist of cable core by many eradications edge core 2 with soft type gasket for packing 3 twisted synthesizing cables and through band 4 wrappings, outside cable core, set gradually the armour 6 that the inner covering 5, knit wire and the filament that extrude formation consist of and the external sheath layer 7 that extrudes formation.
In the implementation, conductor 1 adopts tin-coated copper tow strand, a burst strand circle to press structure; Gasket for packing 3 adopts high strength, super soft, light specific gravity, water-absorption fiber kernmantle not; Armour 6 is identical with the Polyamide Yarns number of spindles for zinc-coated wire, the opposite direction braiding forms; Inner covering 5 and external sheath layer 7 adopt flame-retardant polyurethane thermoplastic elastomer (TPE) or chlorosulfonated polyethylene material to extrude and form.
