Inkampani ye-oyile ye-oyile-entywiliselwe kwi-transformer ejongene nengxaki yomlilo we-transformer, ukuba i-transformer ifunyenwe emlilweni, jonga kuqala i-transformer circuit breaker ikhutshiwe, okwesibini, khangela i-oyile kwi-transformer top cover ivutha, ifanele ibe bhetyebhetye i-casing casing casing. Umlilo kunye negreasy kwisigubungelo somlilo kwiimeko ezahlukeneyo, abathumeli bangaphandle be-oyile abagcwele amandla ngaphambi kokuthumela ngaphandle, intsebenziswano kunye nabathengisi abalungileyo besikhululo sokuthengisa ukuthengisa ngokudibeneyo
