Electricity is an energy that is closely related to people’s daily life, and hot-line connection is often necessary in grid transformation and overhaul. Traditional stripping devices need to be operated manually with tools, which are not only time-and labor-consuming, but also have certain potential safety hazards. In this paper, a special stripping tool that is suitable for 10 kV high-voltage hot-line work is researched and designed based on summary of existing manual stripping devices. This new device is featured by a simple structure, safety, reliability, low operation risk, high efficiency, and a high automation level.
