Communication cable of large gantry crane

The utility model relates to the technical field of cables, and discloses a communication cable of a large-scale gantry crane. The communication cable sequentially comprises filling strips, cable strands and a protective layer from inside to outside, the four groups of cable strands are uniformly distributed on the outer side of the filling strip in a surrounding manner, and each group of cable strands comprises three conductor wires; the thickness of the protective layer ranges from 1.5 mm to 1.8 mm, and the protective layer is made of TPE materials. According to the communication cable of the large-scale gantry crane provided by the utility model, the three conductor wires form a cable strand, and the middle of the cable strand is filled with the filling strips, so that the conductor wires can be kept round and compact, and signals are more stable during transmission. The protection thickness of the protection layer is 1.5-1.8 mm, and the protection layer is made of a TPE material, so that the whole cable c
