The NISELA series environmentally friendly gas-insulated ring main switchgear from XJ Delishier Electric Co., Ltd. can be installed for indoor/outdoor use, including in basements, concrete enclosures, and stainless steel enclosures, suitable for systems with a rated current of 630A, rated voltage of 12kV, and rated frequency of 50/60Hz. All live parts and switches in the ring main switchgear are enclosed in a 3mm 304 stainless steel gas chamber, with vacuum arc extinguishing and environmentally friendly gas (dry air) as the insulation medium. Each functional unit is equipped with a circuit breaker, isolating switch, and grounding switch as needed.

The ring main switchgear is pre-filled with dry air at the specified pressure before leaving the factory. The rated gas pressure of the NISELA series environmentally friendly gas-insulated ring main switchgear is 0.01MPa. The extreme pressure of the NISELA series gas tank is 0.25MPa, at which point pressure will be released through the explosion-proof membrane. The cable bushings in the cable compartment are conical bushings conforming to DIN47636, allowing very convenient connection of incoming and outgoing cables. In addition to cable feeder cabinets (incoming cabinet A, K) and circuit breaker cabinets (V), we can also provide various functional cabinet types such as busbar connection cabinets, metering cabinets (M), and PT cabinets.
