Aplikasyon
Actastheprotectingandcontrollingunitforgridequipmentsandindustrialminingenterprises'equipments, LW8-40.5 tip deyò SF6 sikwi brekè se yon aparèy deyò yo itilize nan AC 50HZ twa-faz 40.5KV pouvwa sistèm.Li aplikab a kote ki bezwen opere souvan nan rated aktyèl oswa anba repete sou / sou kouran sikwi kout. Ki gen transfòmatè aktyèl la pou mezi ak pwoteksyon, li ka dirèkteman ranplase SW2-35 mwens brekè sikwi lwil oliv ak divès kalite brekè sikwi lwil oliv ak bracket tranzisyon. Li kapab tou itilize kòm yon brekè menm kantite vòt ak chanje sitiyasyon gwoup kondansateur ak CT14 mekanis sezon prentan kalite.
