Description

Technical Field

[0001] The utility model relates to a transformer lead insulation wrapping machine, belonging to the technical field of transformer lead wrapping. Background Art

[0002] In recent years, due to changes in product design and process routing, the lead materials used in the sleeve welding process, except for paper-wrapped cables, are not insulated. This requires workers to perform a large amount of manual insulation wrapping during the early stages of transformer manufacturing. Currently, transformer leads that require wrapping primarily include copper pipes and high-voltage wire insulation. These materials are relatively large, and manual insulation wrapping presents the following challenges: 1. Currently, manual wrapping consumes a significant amount of manpower and time, with the initial lead insulation wrapping time for a product accounting for 1 / 10 to 1 / 5 of the total manufacturing time. 2. Manual insulation wrapping also presents issues such as unevenness and insufficient tightness, which can affect the electrical performance of the insulation to varying degrees. Therefore, it is necessary to develop an insulation wrapping machine to replace manual operation. Utility Model Content
