Variable frequency cable

The invention relates to a variable frequency cable, and relates to the field of cables, and the variable frequency cable comprises a plurality of insulating wire cores, a breathable shielding layer wrapping the outer sides of the plurality of insulating wire cores, and an insulating outer sheath layer wrapping the outer side of the breathable shielding layer. A plurality of ventilation areas used for accelerating heat dissipation of the cable are evenly arranged on the insulating outer sheath layer at intervals in the length direction of the insulating outer sheath layer, a plurality of external ventilation grooves are formed in each ventilation area in the length direction and the circumferential direction of the insulating outer sheath layer, and the external ventilation grooves are communicated with the interior of the insulating outer sheath layer. The waterproof self-heat-dissipation mechanism is arranged between the insulating wire cores and the insulating outer sheath layer and used for fixing the ins
