Ellumi-3 type SF6 gas-filled and fully insulated RMU load switch, vacuum circuit breaker and its isolating switch are completely enclosed in a stainless steel airtight box, and the load switch is SF6. Gas arc extinguishing, vacuum circuit breaker adopts vacuum arc extinguishing; Cable connection adopts fully insulated touch plug connector, and transformer adopts fully insulated structure.


Under the premise of sufficient supply, power quality problems have become increasingly prominent, mainly manifested in power factor, harmonics, three-phase unbalance, voltage fluctuations and flicker.

Further developing and using Digital Twin technology covering distribution switchgear maintenance system and power quality comprehensive management to satisfy the users' new demand of energy-saving and carbon-reducing managment.
