NOVELTY - The utility model claims a flexible heating cable bus, comprising an inner core, the outer side of the inner core orderly fixedly connected with a first insulating layer, a shielding layer, a first insulating layer, a heating film, a second insulating layer; a second insulating layer and a buffer layer; the right end of the buffer layer is provided with a first groove distributed with equal distance; the left end of the buffer layer is provided with a second groove distributed with equal distance; the outer side of the buffer layer is orderly fixedly connected with with a woven layer and a third insulating layer. The flexible heating cable bus adopts the design of graphene film, has high heat conductivity coefficient, and does not affect the flexibility of the cable bus, graphene film effectively improves the heat conversion rate, the heating speed is faster, the heating performance is stable, which effectively improves the flexibility of the buffer layer, convenient for bending operation of the cable bus; installation and use is more convenient; the design of the first insulating layer and the second insulating layer effectively reduces the heat loss, improves the utilization rate of the heat, has excellent high temperature resistance, fireproof and flame-retardant effect.
