Kwinkalo yobunjineli bombane kunye nokuhanjiswa kwamandla, "isakhiwo sestation esincinci" sibhekisa kwisakhelo somzimba esixhasa amacandelo ahlukeneyo esitishi. Esi sakhiwo siyimfuneko ekusebenzeni okukhuselekileyo kunye nokusebenza kakuhle kwenkqubo yamandla, ngokukodwa kwimeko yokuhanjiswa kwamandla aphezulu. Ukuhlanganiswa kwensimbi yesakhiwo, insimbi yombane kunye nezinye izinto zidlala indima ebalulekileyo ekuyilweni kunye nomsebenzi we-substation.

Izitishi ziyinxalenye ebalulekileyo yothungelwano lombane, zisebenza njengeendawo eziguqula umbane ukusuka kumbane ophezulu ukuya kumbane ophantsi ukuze usasazwe kumakhaya nakumashishini. Izakhiwo ze-substation ziqulethe izinto ezahlukeneyo, ezibandakanya i-transformers, i-circuit breakers, kunye ne-switchgear, zonke eziyimfuneko ukulawula umbane. Igama elithi "ulwakhiwo lwesikhululo sombane" libhekisa ngokukodwa kubume bombutho kunye nesakhiwo esigcina la macandelo, eqinisekisa ukuba asebenza ngokukhuselekileyo nangempumelelo.

Isinyithi sesona sixhobo sisetyenziswayo ekwakhiweni kwezakhiwo zesikhululo esingaphantsi ngenxa yokomelela, ukuqina, kunye nokukwazi ukumelana nemiba yokusingqongileyo. Intsimbi yesakhiwo isetyenziselwa ukwakha isakhelo esomeleleyo esinokuxhasa izixhobo zombane ezinzima kunye nokumelana neemeko zemozulu ezinzima. Ukusebenzisa intsimbi yombane eyenzelwe ukusetyenziswa kombane kunokunyusa ukusebenza kakuhle kweenguqu kunye nezinye izixhobo ngaphakathi kwesikhululo esingaphantsi.

Uyilo lwesakhiwo se-substation luhlala lubandakanya izibonda zentsimbi, eziyimfuneko ekuxhaseni iingcingo eziphezulu. Ezi pali kufuneka ziyilwe ngononophelo ukuze zimelane nemithwalo emikhulu kwaye zixhathise ukugoba okanye ukwaphuka phantsi koxinzelelo. Ukudibanisa izibonda zetsimbi kwizakhiwo ze-substation ziqinisekisa ukuba inkqubo yokusabalalisa ihlala izinzile kwaye inokwethenjelwa.

Uyilo kunye nokwakhiwa kwezakhiwo zesikhululo esingaphantsi kuxhomekeke kwimigangatho engqongqo yokhuseleko kunye nemimiselo. Ukusebenzisa intsimbi ekumgangatho ophezulu kubalulekile ukuqinisekisa ukuba isakhiwo sinokumelana neziphene zombane, imozulu embi, kunye nezinye iingozi ezinokubakho. Ulwakhiwo lwesikhululo esincinci esiyilwe ngokufanelekileyo sinokunceda ukuthintela iingozi kunye nokuqinisekisa ukhuseleko lwabasebenzi kunye noluntu olungqongileyo.

Ukongeza, uyilo lwesakhiwo sesikhululo esincinci sinempembelelo enkulu ekusebenzeni kokuhanjiswa kwamandla. Isitishi esakhiwe kakuhle sinokunciphisa ilahleko yamandla ngexesha lenguqu nokusasazwa kwenkqubo, ekugqibeleni sifezekise unikezelo lwamandla oluthembekileyo. Ukubekwa kweqhinga lamacandelo ombane ngaphakathi kwesakhiwo se-substation kwakhona kunceda ukwandisa ukusebenza kunye nokunciphisa iindleko zokugcina.
