Steel wire surround closed circular ring shape, the outer layer ring of interior steel wire armor layer is cased with steel band longitudinal wrap layer, twisted ring outside steel band longitudinal wrap layer
It is cased with outer steel wire armor layer, outer steel wire armor layer is that the trapezoidal steel wire of fan surrounds closed circular ring shape by one group of cross section.
It advanced optimizes, copper stranded conductor is annealed copper strand wire.
It advanced optimizes, insulating layer is modified polypropene or fluoroplastic insulation layer.
It advanced optimizes, the cross section of every copper wire of copper stranded conductor is circle, and copper stranded conductor includes a center line and package
One layer of twisted wire layer outside center line.
It advanced optimizes, copper stranded conductor and interior steel wire armor layer orientation are on the contrary, interior steel wire armor layer and outer steel wire armor layer are twisted
To opposite.
It advanced optimizes, steel band longitudinal wrap layer is longitudinally wrapped around on the outside of interior steel wire armor layer by a steel band, longitudinal pair
Seam welds sealing.
Advanced optimize, modified polypropene or fluoroplastic insulation layer with a thickness of 0.55-1.2mm.
It advanced optimizes, the steel wire in interior steel wire armor layer is uniformly distributed, diameter 0.4-1.47mm.
It advanced optimizes, the thickness of strips of steel band longitudinal wrap layer is 0.1-0.5mm.
It advanced optimizes, the steel wire in outer steel wire armor layer is fan trapezoidal wire, and is uniformly distributed, with a thickness of 0.4-
1.47mm。
Beneficial effects of the present invention: coated steel band between steel wire armor layer and cover wire armor in the present invention makes electricity
The hardness of cable rises to original 3 times；The steel wire for forming cover wire armor is trapezoidal using fanning, and greatly reduces armouring steel
Gap between silk, fan trapezoidal wire effectively increases the friction area of steel wire, thus cable caused by avoiding cable from wearing
Can and cable service life decline the problem of, cable smooth in appearance is wear-resisting, can prevent in use cable be hampered, meet card
The appearance of problem, while liquid corrosion object can be reduced and entered inside cable, it prevents cable inner wire to be corroded, guarantees cable
Tensile strength, improve the service life of cable, can simultaneously be effectively prevent downhole oil hydrorrhea from flowing to well face, environment is formed
Certain protection.Cable core copper stranded conductor can transmit signal, the tension of real-time Transmission wirerope, downhole temperature, pressure inside wirerope
Deng, avoid blindly produce, improve working efficiency.
