Xirmooyinka VD4 ee taxanaha Shiinaha VFadlan kala xidhiidh ROCKWILL shuruudaha rakibaadda gaarka ah.VD4-R taxane ah oo dhexdhexaad ah koronto-xumo wareegyada wareegga wareegga ah oo leh habka shaqada ee lateral ee rakibaadda gudaha waxay muujinayaan farsamada dhismaha gaarka ah.Tiir kastaa wuxuu leeyahay vacuum interrupter kaas oo ku dhex jira xabagta marka dhululubada la qaabeeyey iyadoo ay ugu wacan tahay habka wax soo saarka gaarka ah.Habkan dhismuhu waxa uu ka ilaaliyaa faakuumka gooya shoogga, wasakhowga iyo uumiga.
Habka shaqayntu waa nooca tamarta kaydsan ee bilaa safar ah oo leh furitaan madax banaan iyo xidhidh iyada oo aan loo eegin talaabada hawlwadeenka.Habka hawlgalka waxaa si weyn loogu isticmaalaa dhammaan VD4-R taxane wareeg-jabiyeyaal leh kontoroolka hore.
Wareegtada jebiye waa la kontarooli karaa fog marka lagu rakibo qalab koronto oo go'an (matoorka, furitaanka iyo xiritaanka).
Habka hawlgalka, saddexda tiir iyo dareemayaasha hadda (haddii la bixiyo) ayaa lagu rakibay bir aan lahayn taayir.Dhismuhu waa gaar ahaan is haysta, adag oo miisaankiisu xadidan yahay.
VD4-R taxane wareeg-jabiyeyaal leh habab hawlgaleed lateral waa aaladaha cadaadiska nolosha oo dhan shaabadaysan.(Heerka IEC 62271-100)
