Abstract: This article designs an efficient and safe specialized stripping device for PVC insulated wires. The design addresses the application needs of modern electrical engineering by optimizing its structure and key technical parameters.The device consists of cutting tools, clamping devices, and stripping mechanisms, adopting a modular design and precise control system to ensure stripping stability and accuracy. Multivariate tests are conducted to evaluate the stripping efficiency and conductor damage, showing that at a stripping speed of 10 m/min and a clamping force of 200 N, the conductor damage rate remained below 1%, with stripping efficiency exceeding 95%.
