The invention discloses a reinforced anti-extrusion variable frequency cable, which comprises a cable core, wherein the cable core is formed by symmetrically arranging and stranding three main wire cores with large sections and three neutral wire cores with small sections; a gap of the cable core is filled with a filler; a lining layer extrudes and wraps the outside of the cable core; a master shielding layer extrudes and wraps the outside of the lining layer; a sheath extrudes and wraps the outmost layer; each main wire core comprises a main conductor, a separate shielding layer and an anti-extrusion layer; each separate shielding layer extrudes and wraps the outside of each conductor; each neutral wire core comprises a neutral conductor, a separate shielding layer and an anti-extrusion layer; each separate shielding layer extrudes and wraps the outside of the corresponding neutral conductor; a group of reinforcing cores is arranged in the centre of each main conductor; and one reinforcing core is arranged in the centre of each neutral conductor. According to the reinforced anti-extrusion variable frequency cable, the condition that the cable has excellent antistatic coupling capability and anti-electromagnetic induction capability in a use procedure is guaranteed; and the service life of the cable is significantly prolonged, so that the safety and the reliability of the cable are significantly improved; meanwhile, the cost for frequently replacing the cable by users is reduced; and the cable has good social and economical benefits.
