The invention discloses an all-weather halogen-free flame-retardant rat-proof and termite-proof electric wire and cable, and relates to the technical field of electric wires and cables, the electric wire and cable comprises a cable body, the cable body is placed in a flame-retardant shell, and buffer rubber is arranged outside the flame-retardant shell and used for carrying out buffer protection on the cable body during collision. An insulating layer is arranged outside the buffer rubber and used for insulating the cable body, the flame-retardant shell comprises 50-60 parts of butadiene styrene rubber, 30-40 parts of polyolefin resin, 3-5 parts of an antioxidant, 3-5 parts of an anti-aging agent, 10-12 parts of an inorganic additive, 3-5 parts of a compounding agent, 3-5 parts of an accelerant and 2-3 parts of a smoke suppressant, and a winding device is arranged at the end of the electric wire and cable. According to the cable, the halogen-free flame-retardant performance of the cable is ensured by adopting
