NOVELTY - The utility model claims a combined cable, from inside to outside in turn comprises cable core cable, bag belt layer (3), a cooling fireproof tube layer (4) and colour lighting layer (7), the cable core comprises multi-cable of electric power cable core (1) and multiple pieces of single cable core (2) of each electric power cable core (1) is coated with insulation layer (11), each of signal cable core (2), (21), insulation layer (22) and screening layer (23), multiple pieces of electric power cable core (1) and multiple pieces of single core cable (2) after wound wire bag belt layer (3), a cooling fireproof tube layer (4) outside is coated with graphene (5) set with heave is spherical particle in spiral of graphene (5) (6), and luminous layer (7) is uniformly coated on the spherical granule (6) above. The utility model is new type of combined cable has high brightness and colour lighting and automatic cooling structure, signal transmission quality high, using life long, occupying small space, and each of the internal cable not disturb each other.
