Ocean investigation, river, bay, water conservancy, hydrographic survey and coal exploration, geothermal logging etc..Traditional logging cable
It cannot meet present use demand, there is an urgent need for making a change, to meet the needs of market is to the cable.
The structure of existing charge bearing detecting cable is copper stranded conductor, insulating layer, metal armor layers, and the cable of the type was being logged well
Cheng Zhong, for cable after stress, armor presses insulating layer, and copper stranded conductor is tied tight at this time, can be destroyed insulating layer, be caused cable insulation
Performance reduces so that cable leakage current is excessive, and fracture of wire is also resulted in when serious, reduces the service life of cable, while band
Carry out larger security risk, therefore be badly in need of designing a kind of new cable, to solve the above problems.
The content of the invention
Novel in order to compensate for the shortcomings of the prior art, the present invention provides a kind of structure, tensile strength is big, service life length
High intensity hold lotus sealing detection cable.
The present invention is achieved through the following technical solutions：
WMF high-intensity sealing charge bearing detecting cables, it is characterised in that：Include polygon skeleton, polygon skeleton it is every
Bar side is equipped with the circular arc of indent, and the center of the polygon skeleton is equipped with steel wire plying layer, the outside of the steel wire plying layer
Restrictive coating is equipped between polygon skeleton, every circular arc of the polygon skeleton is equipped with copper stranded conductor, and the every copper twists
Ring set has the first insulating layer on the outside of line, and the outside of the polygon skeleton is two-sided water blocking layer, the outside of the two-sided water blocking layer
The second insulating layer of ring set, ring set inner armor layer on the outside of second insulating layer, the armoured layer of ring set on the outside of inner armor layer.
Further, the polygon skeleton is hexagon, octagon or dodecagon, can not only make it that copper stranded conductor is equal
Even distribution is in the cable, moreover it is possible to prevents stress distortion of the cable, influences to use.
The polygon skeleton is rubber material.
First insulating layer is modified polypropene or fluoroplastics material.
The thickness of first insulating layer is 0.45-1.2mm.
Second insulating layer is polypropylene, fluoroplastics, polyethylene, crosslinked polyethylene or polyvinyl chloride.
The thickness of second insulating layer is 0.2-0.8mm.
The inner armor layer forms for individual wire armouring.
The armoured layer is inner surface to face directly or cambered surface, outer surface are adopted for the Z-shaped or serpentine deformed wire of cambered surface
Formed with lock stock formula structure armouring, can stop the entrance of oil, vapour and water, play sealing function.
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.
The beneficial effects of the invention are as follows：The WMF high-intensity sealing charge bearing detecting cables of the present invention, it is reasonable in design, make
Used time is located at the steel wire plying layer stress load-bearing at center, and inner armor layer, armoured layer steel wire are used in combination using different shape,
So that being reduced from turn-week number, beaten during use and turn round phenomenon reduction, armoured layer uses Z-shaped or S-shaped deformed wire, locks stock formula knot
Structure, not only stops the entrance of oil, vapour and water, plays sealing function, moreover it is possible to avoids the occurrence of and jumps silk and lantern phenomenon, suitable promote makes
With.
Brief description of the drawings
The present invention is further illustrated below in conjunction with the accompanying drawings.
Attached drawing 1 is WMF high-intensity sealings charge bearing detecting cable structure diagram of the present invention.
In figure, 1, copper stranded conductor, the 2, first insulating layer, 3, steel wire plying layer, 4, restrictive coating, 5, two-sided water blocking layer, 6 polygons
