Abahlinzeki be-switchgear baseShayina basebenzisa imithombo ehlukahlukene yendima yokuhlinzeka izimele ngokuqhathaniswa, Iphaneli yedrowa ingathatha iyunithi yedrowa njengomzimba oyinhloko, futhi ibe nezakhiwo zokudweba nokulungisa ngesikhathi esifanayo, futhi ingaxutshwa futhi ihlanganiswe ngokuzenzakalelayo, futhi inani eliphezulu lokonga izindleko lingafinyelelwa ngokubonisana kweminyango eyahlukene. Singasebenzisa i-transformer eshibhe kakhulu yokucwiliswa kukawoyela ukuze sithekelise isiguquli esidingwa abatshalizimali bakwamanye amazwe.
