The application discloses an environment-friendly flame-retardant medium-voltage cable and relates to the technical field of cables. A flame-retardant protection assembly is arranged on the outer side of an inner conductor. The flame-retardant protection assembly comprises flame-retardant filling bodies. Support grooves are formed in the middle of the opposite sides of adjacent flame-retardant filling bodies. Arc-shaped spring plates are bonded in the support grooves. Aluminium hydroxide bags are filled in the reinforced braided tubes. Heat-conducting silica gel is wrapped on the outer side of heating wires. Replacement and impurity-removing assemblies are arranged on the outer side of outer protective films. When the outer side of the cable is extruded and collided, the impact force is attenuated layer by layer, so that the damage of the cable caused by the collision is reduced.
