Description

Technical Field

[0001] The utility model relates to the technical field of wire strippers, in particular to a power cable stripper. Background Art

[0002] Power cable, also known as power cable, is a cable used to transmit and distribute electrical energy. It plays a vital role in many scenarios such as urban underground power grids, power station lead-out lines, internal power supply of industrial and mining enterprises, and underwater transmission lines across rivers and seas. The core of the power cable is wrapped with an insulating layer. The presence of the insulating layer will increase the resistance of the joint. Therefore, when connecting the cables, the insulating layer needs to be peeled off to reduce the resistance and make the current transmission smoother.

[0003] The traditional wire stripping method is that workers hold a cutting knife and peel off the insulation layer. However, this method is greatly affected by human factors, and it is difficult to ensure the flatness of the cutting surface, which affects subsequent use. In addition, the manual wire stripping method is prone to cause injuries to workers and has certain risks. Therefore, a power cable stripper is proposed. Utility Model Content
