產品概述 Product brief account

HXGNO-12箱型固定式金屬封閉開關相(簡稱環網相)適用于交流50Hz, 10kV的網絡作為開斷負荷和短路及關合短路電流用。本環網相配用電手' 電動 彈簧機構來操作負荷開關，接電開關和隔離開關配用手動操作機構。

HXGND-12 tank fixed type metal enclosed switchgear(ring unit cubicle)is used for A.C 50Hz,10kV network as broken loading, short-circuit and closing short-circuit. The ring mainunit equiped with manual/electromagnet spring charged operated mechanism to operate loading s witch, earthing switch and isolating switch equiped with manual operated mechanism.
