The utility model relates to a cable, in particular to a fire-resistant cable for a motor
train unit. The utility model aims to provide the fire-resistant network cable for the motor
train unit, and the cable has the characteristics of high
temperature resistance and adaptability to severe environments on the premise of having the
transmission performance of a category 6 enhanced network. According to the technical scheme, the fire-resistant network cable for the motor
train unit comprises a cable core, and a first belting layer, a shielding layer, a second belting layer and an outer protective layer which sequentially wrap the cable core from inside to outside, and is characterized in that the cable core comprises a filling wire and a plurality of conducting wires which are centrosymmetric and are spirally wound on the filling wire; each wire comprises a conductor, a first insulating layer and a second insulating layer, wherein the first insulating layer and the second insulating layer sequentially wrap the conductor.
