Description

Technical Field

[0001] The invention relates to the technical field of cable sheath cutting devices, and in particular to a power cable sheath cutting device. Background Art

[0002] When inspecting and installing power cables, a cable skin cutting device is used to cut off the cable skin, and then the inside of the cable is inspected or the cable core is connected to other cables.

[0003] After searching, the Chinese patent application with application publication number CN115483649A is named as a power cable ring cutting device and power cable damage inspection and repair equipment. The patented device continuously cuts the outer side of the curved part of the cable sheath of the power cable while the cutting knife rotates around the power cable. After the cable sheath of the power cable is cut, the cutting opening is opened, which makes it easy to observe whether the cutting knife cuts the inner lining or inner core of the power cable during the cutting process, thereby improving the safety and reliability of the power cable ring cutting.
