Description

Power switch cabinet ground wire processing device

technical field

The invention relates to the technical field of electric power grounding wires, in particular to a processing device for grounding wires of electric switch cabinets.

Background technique

When performing secondary wiring operations in switch cabinets and high-voltage cabinets, the installation of ground wires is a very important task, and ground wires play a very important role in the protection of lines. In order to facilitate installation and prevent the grounding wire from being squeezed in the cabinet door, the grounding wire needs to be wound, that is, the middle part of the grounding wire is wound into a spiral shape; the current common practice is: hold the screwdriver and one end of the grounding wire with one hand, and hold the screwdriver with one end of the grounding wire with the other Grab the other end of the ground wire in your hand and wrap it around the screwdriver so that the ground wire has several helixes in the middle. This way of winding the grounding wire with bare hands will cause discomfort to the hands, and there is even a danger of scratching the hands.
