Water-proof and mouse-proof compensational cable

The utility model discloses a water-proof and mouse-proof compensational cable comprising a plurality of groups of conductors. Each group of the conductors is formed by two mutually-twisted alloy conductors wrapped with insulation layers; each group of the conductors is successively wrapped with a secondary shielding layer, an elastic layer and a water-proof layer; the plurality of groups of conductors wrapped with the water-proof layers are mutually twisted into a bunch to form a cable core; the cable core is successively wrapped with a main shielding layer, an expanded plastic layer and an outer sheath layer outside; and winding layers are arranged between the expanded plastic layer and the outer sheath layer, the winding layers are formed by spirally twisted steel wires and the spirally twisted distance is less than 3 times of the diameter of the steel wire. The water-proof and mouse-proof compensational cable is well structured and designed, allows the cable to be effectively free from mice and enables hi
