The utility model relates to a power and signal transmission cable for a lift and a mobile device. The power and signal transmission cable is characterized by comprising an abrasion-proof and twist-resistant ethylene propylene sheath, an aramid fiber braid, a non-woven cloth taped covering, a plurality of strands of copper conductors, twist-resistant ethylene propylene insulating layers coated on the surfaces of the copper conductors and aramid fiber reinforcement cores arranged between the copper conductors. The power and signal transmission cable has the advantages that the problems of twist deformation, swelling, cover tearing and core breaking of the cable are solved, the service time of the product is over fourfold that of the conventional cable, the frequent using safety of the lift is ensured, the using amount of the conventional cable is decreased, material energy is saved, the maintenance cost of a lift manufacturer is lowered, and engineering construction efficiency and safety are improved.
