Description
Technical field
The present invention relates to field of cables, particularly relates to WMF high tenacity low stress charge bearing detecting cables.
Background technology
Charge bearing detecting cable is as downhole probe measurement connecting line, while signal is transmitted, also with load bearing equipment
Effect.Existing charge bearing detecting cable, inside and outside armor are that round steel wire armouring forms, and inside and outside armor plying direction phase
Instead, charge bearing detecting cable can be rotated with instrument when going into the well, and excessive rotation inevitably makes cable produce bulge, jump silk,
The service life of cable is reduced, influences the normal use of cable.In summary, it is necessary to a kind of new cable is designed, to solve
The above problem.
The content of the invention
In order to compensate for the shortcomings of the prior art, the present invention provides a kind of WMF high tenacity with new sheathed structure is low
Stress charge bearing detecting cable.
The present invention is achieved through the following technical solutions：
WMF high tenacity low stress charge bearing detecting cables, including copper stranded conductor, insulating layer, armor, it is characterised in that described
Copper stranded conductor centre fills the sand that blocks water, periphery parcel inner insulating layer, and the inner insulating layer outside is set with the pipe that blocks water, the pipe that blocks water
Outside is set with high intensity wrinkle composite alloy pipe, and external insulation layer is filled on the outside of the high intensity wrinkle composite alloy pipe, described outer
The outside ring set of insulating layer has an armor, and the armor of opening is divided into inner armor layer and armoured layer, outside inner armor layer exterior ring cap
Armor, the inner armor layer, armoured layer are formed by armouring after more finer wires plying, and inner armor layer and armoured layer
Armouring direction is opposite.
Further, the copper stranded conductor is copper wire, tinned copper wire or silver-gilt copper wire.
The inner insulating layer is XLPE insulating materials or polyether-ether-ketone, and preferable insulating properties is still kept in higher temperature
Energy.
The thickness of the inner insulating layer is 0.10-0.65mm.
The external insulation layer material is modified polypropene or fluoroplastics.
The thickness of the external insulation layer 2 is 0.45-1.2mm.
It is described to block water the husky, pipe that blocks water to expand the material that blocks water, expansion 2-5mm height per second, when cable head is intake at a high speed
When, the husky energy moment that blocks water prevents water from extending longitudinally, and water resistance is stopped the stem in cable, ensures its electric property.
The copper stranded conductor is single or multicore structure, and when copper stranded conductor is multicore structure, the copper stranded conductor periphery of each core is
Inner insulating layer is enclosed with, adjacent inner insulating layer is set with the pipe that blocks water after being twisted.
The inner armor layer, armoured layer are plied to steel wire rope by more steel wires, and more steel wire rope armourings form, armouring side
To on the contrary, such plying mode can greatly reduce the stress concentration of steel wire, make cable more soft, stress is extremely low,
The rotational steps of cable are reduced during use, prevented cable bulge, jumped the phenomenon of silk.
Fluid sealant is filled between the inner armor layer and armoured layer so that gapless between inner armor layer and armoured layer
In the presence of preventing from being corroded and polluting inside cable.
The beneficial effects of the invention are as follows：The WMF high tenacity low stress charge bearing detecting cables of the present invention, change armouring knot
Structure, by traditional single round steel wire, is changed into steel wire rope of pooling capital, reduces torsion inside cable, improve toughness, be cable when in use
Rotational steps reduce, and solve the problems, such as cable bulge, jump silk, while the cable of the present invention has the function of longitudinal water-blocking, prevents electricity
It is corroded and pollutes inside cable.
Brief description of the drawings
The present invention is further illustrated below in conjunction with the accompanying drawings.
Attached drawing 1 is the structure diagram of WMF high tenacity low stress charge bearing detecting cable of the present invention；
In figure, 1, copper stranded conductor, 2, external insulation layer, 3, inner armor layer, 4, armoured layer, 5, block water sand, 6, high intensity wrinkle
Composite alloy pipe, 7 block water pipe, 8 inner insulating layers, 9 fluid sealants.
Embodiment
Attached drawing is a kind of specific embodiment of the invention.As shown in Figure 1, WMF high tenacity low stresses bearing detection electricity
Cable, including copper stranded conductor 1, insulating layer, armor, copper stranded conductor 1 are copper wire, tinned copper wire or silver-gilt copper wire, are filled among copper stranded conductor 1
Block water sand 5, and peripheral Jacket thickness is 0.10-0.65mm inner insulating layers 8, and inner insulating layer 8 is XLPE insulating materials or polyether-ether-ketone,
Preferable insulation performance is still kept in higher temperature.The outside of inner insulating layer 8 is set with the pipe 7 that blocks water, the pipe 7 that blocks water
Outside suit high intensity wrinkle composite alloy pipe 6, the outside of the high intensity wrinkle composite alloy pipe 6 filling external insulation layer 2 are outer exhausted
2 material of edge layer is modified polypropene or fluoroplastics, thickness 0.45-1.2mm；The outside ring set of the external insulation layer 2 has armouring
Layer, the armor of opening are divided into inner armor layer 3 and armoured layer 4, the armoured layer 4 of 3 exterior ring cap of inner armor layer, the inner armor layer
3rd, armouring forms after armoured layer 4 is pooled capital by more finer wires, and the armouring direction of inner armor layer 3 and armoured layer 4 is on the contrary, interior
Fluid sealant 9 is filled between armor 3 and armoured layer 4 so that gapless exists between inner armor layer 3 and armoured layer 4, prevents
It is corroded and pollutes inside cable.
The sand 5 that blocks water, the pipe 7 that blocks water block water material for expansion at a high speed, expansion 2-5mm per second highly, when cable head into
During water, the husky energy moment that blocks water prevents water from extending longitudinally, and water resistance is stopped the stem in cable, ensures its electric property.
Copper stranded conductor 1 is single or multicore structure, and when copper stranded conductor 1 is multicore structure, the periphery of copper stranded conductor 1 of each core is wrapped
Inner insulating layer 8 is wrapped with, the pipe 7 that blocks water is set with after adjacent inner insulating layer 8 is twisted.
The inner armor layer 3, armoured layer 4 are plied to steel wire rope by more steel wires, and more steel wire rope armourings form, armouring
Direction is on the contrary, when for example more steel wires are plied to steel wire rope, and plying direction is left-hand, and the armouring direction of inner armor layer 3 is dextrad,
Then the armouring direction of armoured layer 4 is left-hand, or inner armor layer 3 armouring direction be left-hand, then armoured layer 4 armouring direction
For dextrad, such plying mode can greatly reduce the stress concentration of steel wire, make cable more soft, and stress is extremely low,
The rotational steps of cable are reduced during use, prevented cable bulge, jumped the phenomenon of silk.
The WMF high tenacity low stress charge bearing detecting cables of the present invention, change sheathed structure, by traditional single round steel
Silk, is changed into steel wire rope of pooling capital, and reduces torsion inside cable, improves toughness, is that rotational steps reduce cable when in use, solves electricity
Cable bulge, jump the problem of silk, while the cable of the present invention has the function of longitudinal water-blocking, prevents from being corroded and polluting inside cable
