In slot；The sub- cable includes both threads core and a tensile cord, and tensile cord is laid out with both threads core in isosceles triangle, and son electricity
Cable further includes the protective layer for wrapping tensile cord and core；The core includes aluminium alloy conductor and is wrapped in aluminium alloy and leads
The insulating layer of external side.
Further, the center-filled body is provided centrally with the second tensile cord, and second tensile cord is steel wire rope.
Further, it is provided with armor between the sheath and insulation outer jacket.
Further, it is provided with flame-retardant layer between the armor and the sheath.
Further, the tensile cord is twisted by more aramid fiber core wires.
Further, the material of the center-filled body is rubber.
Further, the every sub- cable also includes shielded layer, and the shielded layer is wrapped in the tensile cord and line
The periphery of core, the protective layer are arranged in the outside of the shielded layer.
Further, insulation filler is filled in the gap between two sub- cables of arbitrary neighborhood and wrapping layer.
Advantageous effect：It is effectively fixed that the rubber aluminium alloy cable of the utility model carries out sub- cable using center-filled body
Position so that the relative position of three root cables is relatively fixed, and center-filled body has good wrapping property to sub- cable, to
It can effectively improve the crushing resistance of cable；Center-filled body is provided centrally with the second tensile cord, and is all had per root cable
Independent tensile cord, makes cable whole in this way and its internal each section has extremely strong tensile property.
