Description

Technical Field

[0001] This utility model relates to the field of cable sheath removal technology, specifically a cable sheath removal tool. Background Technology

[0002] With the rapid development of underground power cable laying projects, higher requirements have been placed on cable protection. Cable protection conduits are made of polyethylene (PE) and high-quality steel pipes through pretreatment processes such as sandblasting and shot blasting, dip coating or painting, and heat curing. It is one of the most commonly used electrical insulation conduits for protecting wires and cables. It is widely used due to its excellent insulation performance, high chemical stability, rust resistance, resistance to aging, and adaptability to harsh environments. However, these inherent advantages have brought inconveniences in our daily work, especially for cables around one inch in diameter. Workers typically have to manually remove the outer sheath and the insulation of the internal conductors. This process is time-consuming, laborious, and can easily result in finger cuts.

[0003] Therefore, those skilled in the art have provided a cable sheath stripping tool to solve the problems mentioned in the background art. Utility Model Content
