High-altitude cable

The invention discloses a high-altitude cable. The high-altitude cable comprises an inner core layer and a cable core conductor arranged in the interior of the inner core layer in an annular manner. A colored housing layer is arranged on the exterior of the cable core conductor. A crossed crumple hole is arranged in the axial center of the inner core layer. A first elastic layer is arranged on the outer side of the inner core layer. A second elastic layer is arranged on the exterior of the first elastic layer. An anti-drawing filament is arranged in the interior of the second elastic layer in an annular manner. A first anti-drawing filament is arranged between the first elastic layer and the second elastic layer. An armoured layer is arranged on the exterior of the second elastic layer. A second anti-drawing filament is arranged on the outer surface of the armoured layer. The high-altitude cable can bear quite strong axial tension, is not liable to break, quite small in structure size, quite low in cost, quite convenient to manufacture and quite simple to lay and cost is greatly reduced.
