Embodiment Construction
[0014] Such as figure 1 As shown, a kind of anti-seismic cable of the present invention includes the cable core that is stranded by several wire cores, and the wire core is made up of conductor 1 and the insulation layer 2 outside the conductor, and the sheath layer 4 is directly extruded outside the cable core. When extruding, aramid fiber rope is added to fill the gap in the middle of the wire core to form an anti-seismic layer 3 . Conductor 1 is twisted by the sixth conductor, and the pitch ratio of the outermost conductor is 12.
[0015] The above is only a preferred embodiment of the present invention, it should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, some improvements can also be made, and these improvements should also be regarded as the present invention. scope of protection.
