A multi-pulse current channel of a special protection device for a surge protection device is characterized in that a hardware connecting piece is L-shaped, a connecting joint B at the vertical end of the hardware connecting piece is connected with a copper stranded wire, a moving contact is L-shaped, the other end of the copper stranded wire is connected with a connecting joint A at the horizontal end of the moving contact, the copper stranded wire is composed of a plurality of flexible stranded wires, and each stranded wire is formed by stranding a plurality of fine pure copper wires. And each strand of stranded wire is in a single-strand independent state. The back-up protector has the advantages that the current passing capability of the back-up protector is improved, the safety coefficient is improved, and the current passes smoothly; moreover, the connection part is not sparking, thereby effectively reducing the damage to the metal part and the housing caused by a large current during lightning stroke.
