Bayani na samfurin
ZW8-12 jerin injin kewaye karya ne mai daraja karfin wutar lantarki 12kV, uku mataki AC 50Hz da high karfin wutar lantarki waje canza kayan aiki, yafi amfani da canza kawo yanzu, overload yanzu, gajeren kewaye yanzu a kan noma cibiyar sadarwa, birni cibiyar sadarwa da kananan wutar lantarki tsarin. The samfurin gaba ɗaya tsari ne uku-mataki na common akwati irin, uku-mataki injin arc dakin da aka sanya a cikin karfe akwati, amfani da SMC rufi kayan tsakanin mataki rufi da kuma ƙasa rufi, aiki abin dogaro, rufi ƙarfi high.
ZW8A-12 an yi shi ne ta hanyar haɗuwa da ZW8-12 kewaye yanke tare da kewaye wuka, wanda aka sani da haɗuwa kewaye yanke, kuma za a iya amfani da shi a matsayin sassa sauya.
Wannan jerin kayayyakin aiki inji ne CT23 iri spring makamashi ajiya aiki inji, raba zuwa lantarki da hannu.
