Ellumi-3 is a new generation of secondary distribution switch equipment with the feature of SF6 fully insulated, fully enclosed, extensible and maintenance-free. It's designed and developed, manufactured by SCE and has passed the type test by China National Center for Quality Supervision and Test of Electrical Apparatus Products and it's the first choice for distribution in urban and rural area. It can meet the different requirements for power distribution configuration.
1,With load switch, load switch +fuse combination electrical appliances circuit breaker functional unit,flexible for various complete schemes;
2,There are two types of structure for option,common compartment type and external bus expansion type. which can realize flexible combination of various schemes:
3,Small size.light weight,single unit dimension 500x1000x1750mmconvenient for transportation,handling and installation
4,Very suitable for use in places with verytight space requirements such as wind turbine tower.
5,It is easy to operate.safe to use and easy tomaintainno need maintenance for 30 years:
6,Switchgear is fully sealed,without any exposed live partsand can operate in harsh environment for long period.
