Applications in secondary power distribution systems, 6 kV to 40.5 kV medium-voltage gas-insulated ring main units and compact switchgear Including traditional SF6 gas insulation and environmentally friendly dry air insulation, offering advantages such as high reliability, high safety, compact structure, and maintenance-free operation.

Medium-voltage switchgear available in markets such as Europe and Asia is manufactured in accordance with International Electrotechnical Commission (IEC) standards. However, these switchgear units typically feature rear cable connections, making the installation and maintenance of such equipment difficult.

Applications include secondary power distribution systems, 6 kV to 40.5 kV medium-voltage gas-insulated ring main units and compact switchgear, encompassing traditional SF6 gas insulation and environmentally friendly dry air insulation. They offer high reliability, high safety, compact structure, and maintenance-free operation. Suitable for ring network units in secondary power distribution networks, various fixed configurations can meet the needs of most distribution networks.
