The low-voltage cabinets are then transferred to distribution boxes for various power users. The equipment inside is nothing more than some protective devices such as switches and circuit breakers assembled into one.
[0003] At present, the existing high and low voltage switch cabinets generally use the traditional cabinet lead-in method to connect switches. Due to the small operating space inside the switch cabinet, manual lead-in and line arrangement operations are difficult, and it takes a long time to complete all switch lead-in operations, resulting in poor application effect.
