[0034] The flame retardant component and accompanying cable provided by the utility model are configured with a plurality of filling cavities 3 in the protective layer 1 and the filling cavities 3 are filled with a gaseous fire extinguishing medium. When a fire occurs, the protective layer 1 is ruptured by heat so that the gaseous fire extinguishing medium in the filling cavities 3 is discharged to reduce the oxygen concentration in the air, thereby achieving the purpose of flame retardancy and further reducing the spread of the fire. The configuration of the filling cavities 3 reduces the weight of the protective layer 1. The gaseous fire extinguishing medium is lighter than traditional flame retardant materials, thereby reducing the increase in the overall weight.
