NOVELTY - The utility model claims a stress eliminating graphene heating cable, comprising an insulating supporting core layer, the insulating supporting core layer is coated with graphene conductive film; the outer layer of the graphene conductive film is orderly coated with an insulating layer and an armoured layer; the insulating layer and the armoured layer are supported by a plurality of continuous rhombic buffer strips arranged at intervals; and the gap between the insulating layer and the armoured layer is filled with a thermal conductive insulating elastomer; the outer part of the armoured layer is further provided with an outer protective layer. The utility model generates cold and hot alternating in the cable working process, the expansion or contraction of the inner layer will be fed back to the diamond buffer belt; the rhombic buffer belt deforms and reduces stress, and the armour layer can reduce the external pressure of the inner part; at the same time, the thermal conductive insulating elastomer can support; sealing and buffering, also eliminating the gap between the insulating layer and the armour layer, increasing the continuity of heat dissipation and heat conduction.
