SF6 gas insulated ring main unit switchgear, used in secondary power distribution network. It can provide 10 different configurations and is suitable for most switching applications in 12/24/36 kV distribution networks.

SF6 gas insulated ring main unit represent a complete solution for 12/24/36 kV secondary distribution networks.

Our inflatable SF6 metal seal full insulation series ring network switch cabinet has passed the type test of the national occlusal electrical testing center. Widely used in 10KV/6K power distribution system, it is the preferred switch product for various users in urban and rural areas.

switch cabinet is modular unit mode, which can be combined according to different purposes. By the combination of fixed units and expandable units, which substation meets the need of compact switchgear flexible use.

Inflatable ring SF6 cabinet is divided into non-expandable standard configuration and expandable standard configuration. Due to the combination of full module and half module and its own scalability, it has extremely special flexibility. SF6 inflatable ring cabinet implemented GB standard. Under the condition of the interior (20 ℃) run the design life of more than 30 years.

Modularity and external busbar:

Except for the metering module and the circuit breaker module, the width of all modules is only 325 mm.

Transformer protection:

The switchgear can choose between a switch fuse combination and a circuit breaker with a relay to protect the transformer. The switch fuse combination can provide the best short circuit protection, and the circuit breaker with the relay option can provide better protection against low overcurrent. For large transformers, it is always recommended to use a circuit breaker with a relay.

Normal operating conditions:

The rated characteristics of the switchgear are valid under the following environmental conditions:

Minimum ambient temperature: -25°C

Maximum ambient temperature: + 40°C

For different temperature ranges, please contact your sales representative.
