Description

A kind of diglyhus isaea

Technical field

The utility model is related to electric wire field, and in particular to a kind of novel improved flat diglyhus isaea.

Background technology

Diglyhus isaea is the matching used private cable of Electric Submersible Pump Unit, in being laid in oil well, cable lower It is connected with oil-immersed pump, upper end is connected with ground control cabinet.Cable condition of work in oil well is severe, often in high temperature, high pressure, And in the very strong environment of corrosivity such as oily.Electric cable of submersible pump can be divided into circular and two kinds of flat, narrow and small by oil well casing The restriction in space, usual diglyhus isaea is based on flat.Because flat cable is unsymmetric structure, work as power transmission When, the electromagnetic induction produced because of the imbalance in magnetic field can cause magnetic hystersis loss, make electric cable heating, can have a strong impact on making for cable With the life-span, need duty to change cable, not only affect operating efficiency, and can cause a serious accident.

Utility model content

In order to overcome the deficiencies in the prior art, there is provided one kind has magnetic-field strong interference immunity, magnetic-field anti-dry Immunity is strong, stronger oil resistivity, heat-resist, the fast diglyhus isaea of cooling velocity.

For achieving the above object, the utility model provides a kind of diglyhus isaea, including cable core, described cable core by Three cores are arranged in parallel to be formed；Squash type oil proof sheath is extruded outside cable core, interlocking armour is directly dragged outside squash type oil proof sheath Dress layer；Described core by tinned copper conductor, the polypropylene insulation layer of the resistance to copper ion being extruded in outside tinned copper conductor, be woven in Oil resistant bed course outside polypropylene insulation layer and the squash type oil proof sheath being extruded in outside oil resistant bed course are constituted.

Preferably, oil resistant mark band is additionally provided between described oil resistant bed course and squash type oil proof sheath, mark is played and is made With.

Preferably, described oil resistant bed course be Polyamide Yarns braid over braid, to three cores carry out respectively overlap it is wrapped, put up rate 15%-20%。

Preferably, described lock armo layer is stainless steel band, and the rate that overlaps is 30%-50%.

The beneficial effects of the utility model are：

1. the utility model adopts tinned copper conductor, and corrosion resistance is strong, and speed is fast, can improve electric conductivity and weldability.

2. the utility model insulating barrier adopts the structure of polypropylene material, with good electrical property and high-frequency insulation line Do not affected by humidity, density is little, heat-resist, and cooling velocity is fast.

3. the utility model adopts Polyamide Yarns braid over braid so that cable has stronger oil resistivity.

4. the utility model is provided with lock armo layer so that cable has stronger bending resistance, anti-dry with magnetic-field Immunity is strong, and gap is little, and oil resistance is good.

5. inside and outside two-layer squash type oil proof sheath, the duplicate protection oil resistance of cable are adopted.

Description of the drawings

Fig. 1 is structural representation of the present utility model.

Specific embodiment

Below in conjunction with the accompanying drawings and specific embodiment, the utility model is further elucidated, it should be understood that these embodiments are only used for Illustrate the utility model rather than limit scope of the present utility model, after the utility model has been read, art technology Modification of the personnel to the various equivalent form of values of the present utility model falls within the application claims limited range.

As shown in figure 1, the utility model provides a kind of diglyhus isaea, including cable core, described cable core is by three Core is arranged in parallel to be formed；The second squash type oil proof sheath 6 is extruded outside cable core, interlocking armour is directly dragged outside squash type oil proof sheath Dress layer 7；Described core is by tinned copper conductor 1, the polypropylene insulation layer 2 of the resistance to copper ion being extruded in outside tinned copper conductor, volume The oil resistant bed course 3 being woven in outside polypropylene insulation layer and the first squash type oil proof sheath 5 being extruded in outside oil resistant bed course are constituted；Institute Oil resistant mark band 4 is additionally provided between the polypropylene sheath stated and oil resistant bed course, is easy to recognize the core in cable.

Wherein, in order that cable has stronger oil resistivity, oil resistant bed course is Polyamide Yarns braid over braid, to three cores point Do not carry out overlap wrapped, put up rate 15%-20%；

In order that cable has stronger bending resistance, with magnetic-field strong interference immunity, lock armo layer is stainless Steel band, the rate that overlaps is 30%-50%.

The above is only preferred embodiment of the present utility model, it is noted that for the ordinary skill people of this area For member, on the premise of without departing from the utility model principle, some modifications and improvement can also be made, these also should be regarded as category In protection domain of the present utility model.
