Description

A kind of modified model flat diglyhus isaea

Technical field

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

Background technology

Diglyhus isaea is the matching used private cable of Electric Submersible Pump Unit, is laid in oil well, cable lower It is connected with oil-immersed pump, upper end is connected with ground control cabinet.Cable working condition 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.As 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 work efficiency, and can cause a serious accident.

Utility model content

In order to overcome the deficiencies in the prior art, there is provided a kind of to have magnetic-field strong interference immunity, magnetic-field anti-dry Immunity is strong, stronger oil resistivity, heat-resist, the fast modified model flat diglyhus isaea of rate of cooling.

For achieving the above object, this utility model provides a kind of modified model flat diglyhus isaea, including cable core, institute The cable core stated is formed by three cores are arranged in parallel；Lock armo layer is dragged outside cable core directly；Described core by tinned copper conductor, The polypropylene insulation layer of the resistance to copper ion being extruded in outside tinned copper conductor, it is extruded in the outer squash type oil proof sheath of polypropylene insulation layer And the wrapped oil resistant bed course outside polypropylene sheath is constituted.

Preferably, oil resistant mark band is additionally provided between described squash type oil proof sheath and oil resistant bed course, play mark and make 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. this utility model adopts tinned copper conductor, and corrosion resistance is strong, and speed is fast, can improve electric conductivity and weldability.

2. this 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 rate of cooling is fast.

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

4. this 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. squash type oil proof sheath is adopted, the oil resistance of cable is further improve.

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, further elucidate this utility model, it should be understood that these embodiments are only used for Illustrate this utility model rather than limit scope of the present utility model, after this 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, this utility model provides a kind of modified model flat diglyhus isaea, including cable core, it is described Cable core is formed by three cores are arranged in parallel；Lock armo layer 6 is dragged outside cable core directly；Described core by tinned copper conductor 1, squeeze Wrap the polypropylene insulation layer 2 of the resistance to copper ion outside tinned copper conductor, be extruded in squash type oil proof sheath 3 outside polypropylene insulation layer And the wrapped oil resistant bed course 5 outside polypropylene sheath is constituted；Between described squash type oil proof sheath and oil resistant bed course also Oil resistant mark band 4 is provided with, the core being easy in identification 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 are 30%-50%.

The above is only preferred implementation 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 this 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.
