Qalab dhammaystiran oo korantada sare leh (qalabka qaybinta korantada sare) waxaa loola jeedaa qalabka gudaha iyo dibadda ee AC ee ku shaqeeya nidaamyada korantada ee leh 3kV iyo wixii ka sareeya iyo inta jeer ee 50Hz iyo ka hooseeya.Inta badan loo isticmaalo xakamaynta iyo ilaalinta nidaamyada korantada (oo ay ku jiraan warshadaha korontada, substations, xadhkaha gudbinta iyo qaybinta, warshadaha iyo shirkadaha macdanta, iwm.) Marka khadku xumaado, qaybta khaldan ayaa si deg deg ah looga saaraa shabakada korontada, si loo xaqiijiyo Hawlgalka caadiga ah ee qaybta aan cillad lahayn ee shabakada korontada iyo badbaadada qalabka iyo hawlgalka iyo shaqaalaha dayactirka.Sidaa darteed, qalabka dhamaystiran ee korantada sare waa mid aad muhiim u ah gudbinta korantada iyo qalabka qaybinta, iyo hawlgalkeeda badbaadada iyo kalsoonida leh ayaa muhiimad weyn u leh badbaadada iyo hawlgalka nidaamka tamarta.
Qalabka korantada sare leh oo dhamaystiran ayaa loo qaybin karaa:
(1) Qaybaha iyo isku-darkooda: oo ay ku jiraan furayaasha wareegyada, go'doominta furayaasha, furayaasha dhulka, dib-u-soo-celinta, fiyuusyada rarka, xirayaasha, fiyuusyada iyo qaybaha kore beddelo, furaha fur, isku darka furan, iwm.
(2) Qalab dhammaystiran: Isku-dar qaybaha kor ku xusan iyo isku-darkooda iyo alaabada kale ee korantada (sida Transformers, Transformers, Volt Transformers, Capacitors, reactors, arresters, baararka baska, meelaha laga soo galo iyo meelaha laga baxo, xargaha fiilooyinka iyo qaybaha labaad). iwmSida qalabka birta ku xidhan ee shisheeyaha (switchgear), gaaska ku dahaaran birta-ku-xiran (GIS), iyo saldhigyo hore loo sii diyaariyay oo danab sare/voltage hoose ah.
