Summary:The invention discloses a variable frequency cable. The variable frequency cable comprises a cable core and dual insulating layers coating the periphery of the cable core, wherein the cable core comprises three groups of power wire cores; the sealed space formed by the inner sides of the three groups of power wire cores is filled with a semi-conductive filling core, while three neutral wire cores are uniformly distributed in the gaps outside the three groups of power wire cores to jointly form the cable core; the dual insulating layers comprise an inner insulating layer and an outer insulating layer, wherein the inner insulating layer is an irradiation crosslinking polyethylene insulating layer while the outer insulating layer is an irradiation crosslinking low-smoke zero-halogen polyolefin insulating layer; and the exteriors of the dual insulating layers are coated with a filling layer, a non-woven fabric wrapping layer, a shielding layer and a sheath in sequence. According to the variable frequency cable, t
