[0002] Paper covered wire is a wire that is made by extruding or drawing oxygen-free copper rod or electrical round aluminum rod through a die of a certain specification. It is a winding wire wrapped with a specific insulating material. Combined wire is a winding wire composed of several winding wires or copper and aluminum wires arranged according to specified requirements and wrapped with a specific insulating material. It is mainly used for windings of oil-immersed transformers, reactors and other electrical devices.

[0003] In the production process of paper covered wire, the cutting machine is a device specially designed for cutting paper covered wire wrapped by specific insulating materials. This equipment is very important in the electrical industry, especially in the manufacture of transformers, reactors and other electrical equipment, which require precise cutting of paper covered wires to ensure product quality. Existing paper covered wire cutting machines mostly use a single blade.
