Description

Technical Field

[0002] At present, when medium and high voltage cable manufacturers produce medium and high voltage cables, due to product quality problems and the need for treatment of the head and tail traction sections, it is often necessary to strip the insulating layer and reuse the copper conductor. At the same time, as the main power supply line of the urban power grid, medium and high voltage power cables have a large usage base. When the products are updated and a large number of waste cables need to be recycled, it is also necessary to strip the insulation and separate it from the conductor.
