In the environment that the corrosivity such as oily are the strongest.Diglyhus isaea can be divided into circular and flat two kinds.Narrow and small by oil well casing
The restriction in space, usual diglyhus isaea is based on flat.Owing to flat cable is unsymmetric structure, when electric power transmits
Time, the electromagnetic induction produced because of the imbalance in magnetic field can cause magnetic hystersis loss, makes electric cable heating.When oil well casing size allows
In the case of, preferably use round cable.Its uniform electromagnetic field distribution produced of the round cable of symmetrical configuration, interferes little,
Electro Magnetic Compatibility is good, also allows for retractable line when laying in oil well.But, the above-mentioned armouring electric cable of submersible pump of background technology is equal
Be not suitable for using outside well, it is impossible to easily carry out mounting and installation flexibly, during use, have the disadvantage that 1. is existing latent
Oil pump cable uses outside well, it is impossible to freely bend；The most existing electric cable of submersible pump installs inconvenience in well coupling, takes up room
The biggest；The most existing electric cable of submersible pump is repaired replacing technology outside well and is required higher.
Utility model content
This utility model purpose is to provide a kind of square single protective metal shell electric cable of submersible pump, for square single oil-immersed pump electricity
Cable, lays quick, installs fast, changes simple, it is adaptable to oil well outer portion supply of electric power, asks present in solution background technology
Topic.
The technical solution of the utility model is:
A kind of square single protective metal shell electric cable of submersible pump, comprises tin plating stranded conductor, fluoroplastic insulation layer, rustless steel protect
Jacket layer and polypropylene cover layer, extrude fluoroplastic insulation layer outside tin plating stranded conductor, constitutes single core cable；Arrange outside single core cable
Stainless steel sheath layer, extrudes polypropylene cover layer outside stainless steel sheath layer, the profile of polypropylene cover layer is square, has
It is fixed easily the effect being difficult to upset.
Described tin plating stranded conductor is 19 bursts of tin plating twisted copper conductors, and tin plating twisted copper conductors flexibility is more preferable；Described fluorine
Plastic insulating layer, uses φ 90 plastic extruder to carry out insulating exruded, by circular extrusion mould, makes fluoroplastic insulation material tight
Close extruding is wrapped on tin plating stranded conductor, described circular extrusion mould, and its circular cross-section is long-pending and tin plating stranded conductor
Sectional area matches.
Described stainless steel sheath layer is the sheath that stainless strip is welded, and stainless strip is coated on by shaping roller
On fluoroplastic insulation layer, stainless steel sheath layer is made tightly to protect fluoroplastic insulation layer, stainless steel sheath layer to have good homogenizing
Electric field and mechanical protection effect.
Described polypropylene cover layer, for polypropylene material, has good electrical property and mechanical performance, polypropylene cover layer
As plastic protective jacket layer, for square, have and be fixed easily the effect being difficult to upset.
The beneficial effects of the utility model are: 1, single-core cable has the simple advantage easily repairing replacing of dismounting；2, metal
Sheath substantially increases the mechanical performance of cable, and more effectively isolates external environment, and protective metal shell improves the use peace of cable
Full performance；3, square structure oversheath make core be difficult to rotate turn round bad, have be fixed easily be difficult to upset effect.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment；
In figure: tin plating stranded conductor 1, fluoroplastic insulation layer 2, stainless steel sheath layer 3, polypropylene cover layer 4.
Detailed description of the invention
Below in conjunction with the accompanying drawings, by embodiment, this utility model is described further.
A kind of square single protective metal shell electric cable of submersible pump, comprises tin plating stranded conductor 1, fluoroplastic insulation layer 2, rustless steel
