Description
Technical field
The present invention relates to cable, more particularly to WMF shield sheaths charge bearing detecting cable.
Background technology
With the appearance of the fast development of wire logging techniques, and new logger, it is matched use hold lotus
Detect cable production technology increasingly perfect, this kind of cable is mainly used in all kinds of oil, gas well as weight apparatus measures connecting line is hung
The operation such as well logging, perforation, coring；Oceanographic survey is can also be used for, river, bay, water conservancy, hydrographic survey and coal field geology are surveyed
In terms of spy, geothermal logging.
In above-mentioned cable, there are deep-well cable, ultradeep well cable and special ultradeep well cable respectively.The weight capacity of cable,
The external diameter accuracy of manufacture and signal transmission capabilities play a decisive role to cable quality.
But, traditional charge bearing detecting cable is in process of production because joint processing, the cotton thread filling of twining package tape are non-round
Whole the problems such as, causes cable core outside diameter of cable tolerance after armouring bigger than normal, the problem of even cable is super thick.
Simultaneously as multicore logging cable cotton thread fills not rounding, the laying up diameter inequality with wrapped rear cable is shielded, under
One procedure（Armouring process）Scheduling and planning it is difficult, cable can be caused to jump silk, dissipate head when serious；Occur snakelike curved.
Armor is all to be surrounded by one group of cross section for circular steel wire arranging inside and outside traditional charge bearing detecting cable in addition
Composition, has that gap is larger between steel wire, and the friction area between neighboring armatures layer steel wire is very small, when steel wire is by ambient pressure
When, there is the trend to centre extruding in the steel wires of both sides, then in the middle of the steel wire that is extruded will stress protrude from original armor
Overall structure, easily rubbed, cause armor globality be destroyed, the depression of bearing force of cable.Meanwhile, " jump silk ",
Abnormity is almost changed into its section of cable after " bulge " by original for circle, can just be hampered in use, block
Stagnant situation
Therefore, the cable of brand new how is designed, is those skilled in the art's urgent need to resolve to solve the above problems.
The content of the invention
The present invention is in order to make up the deficiencies in the prior art there is provided simple in construction, and long-lived WMF shield sheaths hold lotus
Detect cable.
The present invention is achieved through the following technical solutions：

Formation cross-section is circular closed structure；Inside and outside armor using fan ring like steel wire, greatly reduce armouring wire it
Between gap, the rigidity and intensity of cable are further enhancing, so as to so that cable use environment is more extensive, use the longevity
Life is also corresponding to be increased.
The inner armor layer outward flange is provided with triangular groove, and armoured layer inward flange is provided with triangular hill, recessed
Groove mutually coincide in raised, can increase fixed fastness, it is ensured that cable is good in poor use environment to hold lotus
And transmitting effect.
The WMF shield sheath charge bearing detecting cables of the present invention, the rubber skeleton is triangle skeleton, and copper stranded conductor distribution is solid
Inside and sharp corner due to rubber skeleton, rubber skeleton can preferably fix multigroup copper stranded conductor, it is ensured that preferably make
With intensity and longer service life.

Semi-conductive shield, semi-conductive shield is that semiconductor electromagnetism glue-line can eliminate the interference of core part electromagnetic field, it is ensured that signal
Efficiency of transmission.
The WMF shield sheath charge bearing detecting cables of the present invention, the shield sheath thickness degree is 0.1-0.5mm.
The WMF shield sheath charge bearing detecting cables of the present invention, the insulating barrier material is MODIFIED PP or fluoroplastics, PP anti-impacts
Hit that characteristic is preferable and ductility/strength is relatively low, it is ensured that on the premise of insulation, be further ensured that the impact resistance of cable and low
Ductility.
The WMF shield sheath charge bearing detecting cables of the present invention, the thickness of the insulating barrier is 0.55-1.2mm.
A diameter of 0.4mm of round wire in the WMF shield sheath charge bearing detecting cables of the present invention, the copper stranded conductor.
The WMF shield sheath charge bearing detecting cables of the present invention, the thickness of the armoured layer is 0.5mm.
The beneficial effects of the invention are as follows：
The WMF shield sheath charge bearing detecting cables of the present invention, armor greatly reduces armouring wire using fan ring like steel wire
Between gap, be coated with sealant layer between ectonexine armor, inside and outside armor is respectively formed closed structure, the annular steel of fan
It is firm that the groove that silk effectively increases on the friction area of steel wire, armor is connected between projection adds scallop wire
Property, solve traditional cable steel wire in use serious wear and cause the problem of bearing capacity declines, while fan annular
Section of steel wire product increase, the bearing capacity for making cable overall is improved, and shield sheath layer is obtained by extruder extrusion, compared to
The wrapped situation of cotton thread filling, twining package tape, cable shield restrictive coating uniform external diameter, the softer high resilience of quality, it is easy to cable
Armouring is produced, and greatly reduces the situation of cable oversize.
