The high-voltage electrical equipment tank is not only a container for insulating oil (such as mineral oil) but also serves as the load-bearing body for core components (such as arc extinction chambers, iron cores, windings), and plays a key role in heat dissipation, insulation, and mechanical support. Therefore, its manufacturing quality requirements are extremely high, ensuring sealing integrity, mechanical strength, cleanliness, and dimensional accuracy. A modern tank production line integrates various technologies including sheet metal processing, welding, surface treatment, and non-destructive testing, demonstrating a high degree of specialization and automation. The high-voltage electrical equipment tank production line is a typical heavy metal structure manufacturing system. Unlike precision electronic assembly lines, it demands equally stringent requirements for process discipline, welding technology, and quality inspection. By introducing automated welding robots, intelligent positioning equipment, and advanced leak detection technologies, it transitions from traditional "craftsman-style" production to a digital, standardized, and highly efficient modern manufacturing model, thereby laying a solid foundation for the long-term safe and stable operation of high-voltage electrical equipment.
