The invention relates to a thin-wall crosslink low smoke cable for ships communication or control signal and a preparation method thereof. The cable structure is that the outer layer of a multi-strand conductor is an insulating layer, the outer layer of the insulating layer is a shielding layer, the outer layer of the shielding layer is a lapped covering, the outer layer of the lapped covering isarmor, and the outer layer of the armor is a sheathed layer. The preparation method is as follows: a line-cable stranding machine strands tin plated copper wire as a conductor; an extruder is utilized to manufacture the insulating layer outside the conductor, the insulating layer is subjected to irradiation and crosslinking by an electron accelerator; a cable former is ustilized to strand insulated wires together; the shielding layer and the armor are braided by utilizing a braiding machine; and the sheathed layer is manufactured by the extruder, and the sheathed layer is subjected to irradiation and crosslinking by the electron accelerator. The thin-wall crosslink low smoke cable has the advantages of small outside diameter, light weight, ageing resistance, tear resistance, heat oil resistance, high flame retardancy, low smoke, no halogen, low toxicity and good ability of keeping excellent electrical performance and mechanical property in hostile environment, wherein the weight of the thin-wall crosslink low smoke cable is 30%-45% lighter than that of common cables.
