AC Fixed Metal-clad Switchgear

XGN66-12 AC Fixed Metal-clad Switchgear is a new generalion of high-voltage electrical complete set producls. it compies with thenationalstandard GB3906 "10-35KV Ac Meta. Enclosed Switchgear" and thepower industry standard DLT404-1997 "Technical Conditions forindoorAC High-voltage Switchgear Orders" it also meets the intenationalstandard lEC62271-200 "AC Mela-Enclosed Switchaear ancControlEquipment Above ikV and Below 52kv." it has the "five-prevention"interlocking funcion.This product absorbs advanced foreignlechnology and is designedand developed to address the high accident rale and large volumeissues of similar exising switchgear in operatiorin China. it has theadvantages of small size, occupying only 50% of the volume ofordinary switchgear. The circuit breaker is reliable and hasgoodperformance, and the "fve-prevention" interlocking mechanism isreliable and simple
