1. Product Overview This production line provides a complete automated assembly solution for the large-scale manufacturing of ring main units (RMU), suitable for the assembly, testing, and line-off transfer of medium voltage switchgear cabinets at 10 kV and below.
Ring Main Unit (RMU, also known as ring‑network load switchgear) is core power supply switching equipment applied in medium‑voltage distribution networks (mainly 10 kV/20 kV). Featuring a metal‑enclosed enclosure, it integrates components such as load switches, fuses, earthing switches and instrument transformers. It is specially designed for power distribution, line protection, fault isolation and flexible switching operations in ring‑type power supply systems.
