| Zusammenfassung: | The invention discloses a piston for a method for penetrating an electric wire through air. The piston is the main braking for air and commonly plays effects with an air cylinder. After the piston is braked through a gearbox gear, air is used for penetrating the electric wire into a pipeline, the used air is used for replacing an iron wire for penetrating electric wire, the number of persons is reduced, the iron wire is eliminated, and potential safety hazards caused by throwing of waste iron wires are avoided on the aspect of safety. |
