[0002] With the acceleration of urbanization, the reliability requirements of distribution network power supply are gradually increasing. At the same time, many urban distribution rooms have a long history. During the construction of distribution network projects, tasks such as load transfer, emergency repairs, relocation, and replacement of old equipment are often encountered. Such tasks require the high-voltage cables to be shut down and the original cables to be cut off for connection or removal. Usually, before the power-off cables are cut off, destructive puncture tests need to be carried out on the cables to be cut off. Cable nailing and cutting equipment are required to complete the entire process.
