Description

Technical Field

[0001] The utility model relates to the technical field of cutting equipment, in particular to a wire trough cutter with accurate positioning and simple operation. Background Art

[0002] PVC plastic cable trunking has the characteristics of insulation, arc protection, flame retardancy, and self-extinguishing. It is mainly used for the internal wiring of electrical equipment. It has protective and electrical protection effects on the laid wires in electrical equipment of 1200V and below. After using PVC cable trunking, it is convenient for wiring and can make the wiring more neat and beautiful.
