Summary of the invention

To solve the above-mentioned problems, the utility model proposes a kind of tension power cables.

A kind of tension power cable, including array cable core, the cable core include tinned copper wire conductor, are extruded in plating Polyether-ether-ketone insulating layer outside tin copper wire conductor is provided with the tension virtue for providing support at the cable center position The outside of synthetic fibre circle rope, the tension aramid fiber circle rope extrudes the tensile device for being improved cable inner tensile performance, and described is anti- Drawing device includes being extruded in tension aramid fiber to justify the tensile layer one outside restricting, the tensile layer two being extruded in outside tensile layer one, extrude Tensile layer three outside tensile layer two, the array cable core and tensile device are twisted, outside the array cable core Portion is surrounded with aramid fiber braiding tensile layer, and the outside of the aramid fiber braiding tensile layer is surrounded with brass wires braided armored shielded layer, institute The outside for the brass wires braided armored shielded layer stated is extruded with polytetrafluoroethylene (PTFE) oversheath.

The tensile layer one, tensile layer two, tensile layer three are that polyvinylamine is made.

Between the tensile layer one and tensile layer two, it is provided between tensile layer two and tensile layer three and is mentioned for damping The spring one and buffer layer of drawing, the buffer layer are PU foam fragment.

The spring two for improving stability and pull resistance is provided between the adjacent cable core.

Between the tinned copper wire conductor and polyether-ether-ketone insulating layer, aramid fiber braiding tensile layer and polyether-ether-ketone insulating layer Between be provided with for provide buffering glass buffer layer.

The beneficial effects of the utility model are: being had using tensile layer one, tensile layer two made of polyvinylamine, tensile layer three There are waterproof and dampproof, sealing, the performances such as resistant to chemical etching, while tensile property is strong, improves the tension of cable entirety and anticorrosive Performance；It can be provided using place, cable center is located at as round restrict of the tension aramid fiber that supports and improve inside cable for entire cable The twisted place of the heart, improves the stability inside cable；Internal stability is further increased using spring one and spring two simultaneously；Benefit The fire protecting performance inside cable can be improved while improving cable internal damping performance with glass buffer layer.

Detailed description of the invention

The present invention will be further described with reference to the accompanying drawings and examples.
