JCZ5-12 / 7.2KV High-voltage Nqus Contactor
JCZ5-12 / 7.2KV High-voltage Nqus Contactor
Lub series JCZ5 ntawm high-voltage nqus contactor yog tsim rau kev faib system ntawm metallurgy, mine, petrol-chemistry thiab lub tsev, tswj cov khoom siv hluav taws xob xws li high-voltage motor ntawm 7.2kV lossis qis dua 7.2kV rau JCZ5-7.2 hom thiab 12kV lossis qis dua 12kV rau JCZ5-12 hom, transformer thiab capacitor loading thiab lwm yam. Tshwj xeeb tshaj yog haum rau kev ua haujlwm nquag.Nws nta nyob rau hauv nws cov ntim me me, lub teeb yuag thiab ntim cov qauv tsim ntawm sab sauv thiab qis.Nws yog qhov yooj yim rau siv thiab tswj, thiab yooj yim los tsim cov cuab yeej ua tiav ntawm FC voj.
