The cross sections of the zero-line copper conductor and the live wire copper conductor are both flat shaped. The zero line copper conductor and the live wire copper conductor are covered with the flame retarding layer, the interference shielding layer and a polyvinyl chloride outer sheath layer at the outside. The elliptic elastic body is arranged between the zero line copper conductor and the live wire copper conductor so as to separate the zero line copper conductor and the live wire copper conductor. The polyvinyl chloride outer sheath layer is provided with the airbag elastic layer at the outer side. A plurality of airbags are arranged in the airbag elastic layer. The airbags are filled with air. The anti-extrusion compensation copper cable is low in production cost and has excellent dampproofness, wear resistance and flame retarding characteristics and the interference resistance capability of the compensation cable is improved and safe and stable operation of the cable is ensured; and moreover, the elastic protection layer is arranged at the outmost layer of the cable and the elastic protection layer is provided with the airbags so that the safety of internal wires can be protected effectively.
