Izinkampani ezikhiqiza futhi zisakaze ugesi zincike kakhulu kuma-Ring Main Units (RMU) ekuhlinzekeni ugesi. Zisiza ekuphatheni nasekulawuleni amanethiwekhi ama-switchgear amancane ngokusebenzisa izici zokuvikela ezisebenza ezinhlelweni zamandla aphansi. Njengoba umkhakha uqhubeka ulungisa izindlela zawo, singabona ngokucacile indima nezinzuzo ama-RMU anazo ngokuphepha nangokwethenjelwa kwezinhlelo zikagesi. Ama-Ring Main Units avumela ukusabalalisa amandla ngendlela ejikelezayo evumela ukuphelelwa amandla nokuvumelana nezimo kuyo yonke inethiwekhi. Lokhu kusho ukuthi ama-RMU angashintshana imizila eya kwenye indawo uma kwenzeka kunokuhluleka ohlelweni olulodwa. Ngale ndlela, izinhlelo ezinamandla angahle zinciphise kakhulu isikhathi sokuphumula kuyilapho zandisa ukusebenza kahle kwamandla anikeziwe. Ama-RMU asetshenziswa kakhulu ezindaweni ezinkulu kanye nasezitshalweni zezimboni kanye nasezinhlelweni zamandla avuselelekayo lapho ukuthembeka kwamandla kubalulekile. Ukusetshenziswa kwama-RMU konga isikhala ngoba mancane futhi acinene, okuwusizo kakhulu ezindaweni zasemadolobheni nasezifundeni ezinabantu abaningi. Ngaphezu kwalokho, izici zokuzenzakalela ezinikezwa ama-RMU anamuhla zivumela ukuqapha okude nokulawula amanethiwekhi kagesi, ngaleyo ndlela kwandise ukusebenza kahle kokusebenza. Njengoba sekwanda ukufuna ukusebenza kahle nokuhlala isikhathi eside, ukuhlanganiswa kobuchwepheshe obuhlakaniphile kuma-RMU sekujwayelekile. Ngaphandle kwalezi zinzuzo, ama-RMU anikeza nezinzuzo zezomnotho njengoba ebiza kancane ukugcina, kunciphisa kakhulu izindleko zokusebenza zezinkampani zikagesi. Iningi lemisebenzi yokuhlola nokugcina ingenziwa ngaphandle kokuphazamiseka okukhulu kokuphakelwa kukagesi. Izici ezenza kube lula ukugcina ama-RMU zithuthukisa ukuthembeka kohlelo, zandise isikhathi sokusebenza kwemishini futhi zinciphise izindleko lapho zinikeza ugesi kubathengi. Uma sibheka phambili, kubonakala sengathi ukusetshenziswa kwama-Ring Main Units kuzokwanda ngokushesha. Lokhu kungenxa yokuthi ama-RMU kulindeleke ukuthi asize ukushintshela emhlabeni wonke emithonjeni yamandla avuselelekayo kanye namasu we-smart grid. Ngaphezu kwalokho, ukuthembela okukhulayo ezimotweni zikagesi kanye nemithombo yamandla ehlukanisiwe kuyizici ezengeziwe ezizodinga ama-RMU athuthukile wokulawulwa komthwalo ozinzile kanye nokunikezwa kwamandla okungaphazanyiswa. Ukufingqa, ama-RMU abaluleke kakhulu ezinhlelweni zamandla zanamuhla. Ngaphandle kokuthembeka nokusebenza kahle kwazo, ziyaguquguquka ngokwanele ukuba zingene kunoma iyiphi inhlangano noma isimiso sezimboni. Ukuthembeka, ukusebenza kahle, ukuguquguquka, nokuzivumelanisa nezidingo zamandla zesikhathi esizayo konke kubonisa intuthuko eqhubekayo kwezobuchwepheshe be-RMU.
