METAL ENCLOSED CUBICLES (METAL ENCLOSED SWITCHGEARS)

 

 

 

 

EVA Air Insulated Metal Enclosed Switchgear is medium voltage switchgear equipments used for reliable distribution of electricity in 12 kV , 24 kV and 36 kV secondary distribution systems according to the customer’s different requirements. EVA Air Insulated Metal Enclosed Switchgears are highly suitable for use in Monoblock Concrete Kiosk ( Monoblok Transformer Substation , Concrete Kiosk ) , Prefabricated Concrete Kiosk ( Prefabrikated Transformer Substation), Metal Sheet Transformer Substation (Metal Sheet Kiosk) indoor environments, industrial production facilities and compact type substation buildings. Thanks to modular construction for easy installation, EVA Air Insulated Metal Enclosed Switchgear can easily meet all the requirements of clients; they can be quickly installed. In these cells, the output busbars are air insulated and the electrical insulation and breaking operations are performed in SF6 gas or Vacuum environment. In this way, maximum safety operation can be achieved within minimum distances. EVA Air Insulated Metal Enclosed Switchgears are also preferred by customers is characterized by the metal partitioning (PM) structure, the LSC2B service continuity loss category and the AFL internal arc classification structure. The inside of the SF6 Gas or Vacuum Circuit Breaker, SF6 Gas Load Break Switch meets maximum user and system security at the highest level.
