Abstract
The utility model relates to a cable, in particular to a buffer type electric submersible pump power cable capable of resisting temperature of 260 DEG C. The utility model adopts the technical scheme that: the buffer type electric submersible pump power cable capable of resisting the temperature of 260 DEG C mainly comprises a conductor, an insulating layer, a thermosetting resin liner, a lead sheath, a wrapping oil-resisting layer and a steel belt interlocked armor layer, wherein the insulating layer is formed by combining a polyimide film (FHF) sintered insulating layer and a polyfluoroalkoxy (PFA) extruded insulating layer; the thermosetting resin liner is arranged outside the insulating layer; three conductive insulating wire cores are arranged in parallel; and the steel belt interlocked armor layer is arranged outside the three conductive insulating wire cores. The buffer type electric submersible pump power cable capable of resisting the temperature of 260 DEG C has the advantages that: the FHF sintered insulating layer and the PFA extruded insulating layer are adopted for insulation and adhered into a whole by adhesion of the FHF, and can operate at the temperature of above 260 DEG C for a long time; the insulating performance of the cable in the using process is guaranteed in a combined insulation mode; the cable can be doubly protected by arranging the thermosetting resin liner outside the insulating layer; and the problems that the level of temperature resistance of the conventional material cannot meet the requirement and a high-temperature-resistant material is easy to puncture when mechanical damage is caused are solved.
Description
Technical field
The utility model relates to a kind of cable, 260 ℃ of electric submersible pump power cables of particularly a kind of buffer-type heatproof.
Background technology
260 ℃ of electric submersible pump power cables of existing heatproof adopt PFA insulation, PFA sheath, steel band lock armo structure; Serviceability temperature can reach requirement; But owing to insulating barrier, restrictive coating processing thinner thickness, bruise resistance is poor, influences the useful life and the performance of cable.
Summary of the invention
The purpose of the utility model is exactly the above-mentioned defective that exists to prior art, provides a kind of buffer-type heatproof 260 ℃ of electric submersible pump power cables, and it can normally be used when the well temperature is spent greater than 240, and useful life and performance can both satisfy instructions for use.
Its technical scheme is: mainly be made up of conductor, insulating barrier, thermosetting resin lining, lead sheath, wrapped oil resistant layer, steel band lock armo layer; Described insulating barrier adopts film sintered insulating barrier of FHF and PFA extruded insulation layer to combine; And outside insulating barrier, add one deck thermosetting resin lining; Three conduction insulated wire cores are arranged in parallel, and process steel band lock armo layer outward.
Above-mentioned lead sheath is provided with wrapped oil resistant layer outward.
The beneficial effect of the utility model is: FHF is film sintered, PFA extrudes combined insulation, and through the adhesivity that the FHF film carries two kinds of material bondings is one, and the normal phase working temperature of these two kinds of materials is all more than 260 degree; Guarantee cable insulation property in use through the combined insulation form, adopt the form that adds lining to realize the duplicate protection to cable, solved the conventional material temperature resistant grade and do not reached requirement, exotic material runs into the problem that mechanical damage punctures easily.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model;
Among the last figure: the film sintered insulating barrier of conductor 1, FHF 2, PFA extruded insulation layer 3, thermosetting resin lining 4, lead sheath 5, wrapped oil resistant layer 6, steel band lock armo layer 7.
Embodiment
In conjunction with accompanying drawing 1, the utility model is done further to describe:
The utility model mainly is made up of conductor 1, insulating barrier, thermosetting resin lining 4, lead sheath 5, wrapped oil resistant layer 6, steel band lock armo layer 7; Described insulating barrier adopts the film sintered insulating barrier 2 of FHF to combine with PFA extruded insulation layer 3; And outside insulating barrier, add one deck thermosetting resin lining 4; Three conduction insulated wire cores are arranged in parallel, and process steel band lock armo layer 7 outward, are provided with wrapped oil resistant layer 6 outside the above-mentioned lead sheath 5.
During making, adopting single real core copper free wire is conductor, and the wrapped sintering of FHF film is as the ground floor insulating barrier; FHF is film sintered, PFA extrudes continuous production, and as complete insulating barrier, continuous vulcanization mode processing thermosetting resin is as lining; Squeeze plumbous form continuously and add lead sheath; The wrapped wrapped oil resistant layer of fabric strip that adds of PTFE film, three conduction insulated wire cores are arranged in parallel, processing interlocking steel-tape armouring layer.
The insulation form that the utility model is selected for use is that FHF is film sintered, PFA extrudes combined insulation; And the adhesivity that carries through the FHF film is one with two kinds of materials bondings; The normal phase working temperature of these two kinds of materials is all more than 260 degree; Process one deck thermosetting resin then and do this lining, adopt lead to make sheath.Guarantee cable insulation property in use through the combined insulation form, adopt the form that adds lining to realize the duplicate protection to cable, solved the conventional material temperature resistant grade and do not reached requirement, exotic material runs into the problem that mechanical damage punctures easily.
