Zusammenfassung:An impact-resistant electric wire and cable comprises a steel core, an inner protective layer is arranged outside the steel core, a plurality of wire cores are arranged between the inner protective layer and the steel core, a shielding layer, a waterproof layer and a flame-retardant layer are sequentially arranged outside the inner protective layer, a leakage-proof layer is arranged outside the flame-retardant layer, an armor layer is arranged outside the leakage-proof layer, and a plurality of fixing rings are sleeved outside the flame-retardant layer. The multiple fixing rings are distributed along the axis of the steel core at intervals, five supporting rods are fixed to the fixing rings and distributed along the axis of the steel core in a circumferential array mode, and the ends, away from the fixing rings, of the five supporting rods are connected with the leakage-proof layer. The anti-compression performance of the cable can be improved, the anti-impact performance of the cable in use is improved, and
