Abaguquli bamandla zixhobo zombane, kukho izizathu ezininzi zokuqhuma, ezifana nesekethe emfutshane okanye isekethe evulekileyo ayifumanekanga ngexesha, ibangela ubushushu be-transformer, ekhokelela ekuqhumeni kwe-transformer, i-substation ehlangeneyo ayifani nengozi yokuqhuma kwe-transformer, yilungise ngesandla, kodwa ke, ukhetho lwe-transformer lubaluleke kakhulu, abathengisi baseTshayina abathumela ngaphandle baya kuthengisa i-transformer ngexabiso eliphantsi, kodwa baya kuqinisekisa umgangatho.
