Description
RM6-12 inflatable SF6metal-enclosed fully insulated ring network switch cabinet is widely usedin 10KV/6K power distributionsystem.It is the preferred switch product for all kinds of power distribution systems in urban and rural areas.
The switch cabinet is a modular unit model,which can be combined according to different USES.The combination of fixed unitsand expandable units meet the needs of flexible use of compact switchgear in various substations.
The RM6-12 inflatable switchgear is a fully sealed system with all live parts and switches enclosed in a stainless steel housing.The entire switch device is not affected by externalenvironmental conditions,so as to ensure the reliability of operation and personalsafety,and to achieve maintenance-free.By selecting an extensible bus,any combination can be achieved to achieve full modularity.Extended bus safety insulation and shielding ensure high reliability and safety.RM6-12 inflatable switchgear can also providetv-style automation solution,forming the concept of intelligent switch,and reduce the field installation and debugging workload to aminimum.
The RM6-12 inflatable switchgear cabinet is divided into non-extended standard configuration and expandable standardconfiguration.Because of the combination of full module and half module and its own extensibility,it has very special flexibility.The RM6-12inflatable switch performs GB standard.The design life of operation under indoor conditions(40℃) and outdoorconditions (-50℃) exceeds 30 years.
