I-China lelinye lamazwe ambalwa ehlabathini asebenzisa amalahle njengowona mthombo walo wamandla. Ityebile ngamalahle, amandla ombane, namandla omoya, kodwa oovimba bayo beoyile negesi yendalo balinganiselwe. Ulwabiwo lwemithombo yamandla kwilizwe lam alulingani ngokugqithisileyo. Ngokuqhelekileyo, i-North China kunye nomntla-ntshona we-China, njenge-Shanxi, i-Inner Mongolia, i-Shaanxi, njl., zizityebi kwimithombo yamalahle; imithombo yamandla yamanzi igxininiswe ikakhulu eYunnan, eSichuan, eTibet nakwamanye amaphondo asemzantsi-ntshona kunye nemimandla, enomahluko omkhulu wokuphakama; imithombo yamandla omoya isasazwa ikakhulu kwimimandla yonxweme olusemzantsi-mpuma kunye neziqithi ezikufutshane kunye nemimandla esemantla (kuMntla-mpuma, eMntla China, kuMntla-ntshona). Amaziko omthwalo wombane kwilizwe lonke agxile kakhulu kwiziseko zemveliso yezoshishino nezolimo kunye neendawo ezinabantu abaninzi njengeMpuma yeChina kunye nePearl River Delta. Ngaphandle kokuba kukho izizathu ezikhethekileyo, izityalo ezinkulu zamandla zakhiwe ngokubanzi kwiziseko zamandla, ezikhokelela kwiingxaki zokuhanjiswa kwamandla. Iprojekthi ye-"West-to-East Power Transmission" yeyona ndlela iphambili yokuqonda ukuhanjiswa kwamandla.

Umbane wahlukile kweminye imithombo yamandla kuba awunakugcinwa kumlinganiselo omkhulu; ukuveliswa, ukuhanjiswa kunye nokusetyenziswa kwenzeka ngaxeshanye. Kufuneka kubekho ulungelelwaniso lwexesha lokwenyani phakathi kokuveliswa kombane kunye nokusetyenziswa; Ukusilela ukugcina le bhalansi kunokubeka esichengeni ukhuseleko kunye nokuqhubekeka kobonelelo lombane. Igridi yombane liziko lombane lenkqubo elenziwe zizixhobo zombane, izitishi ezincinci, iintambo zothumelo, iziguquli zokuhambisa, iintambo zokuhambisa kunye nabasebenzisi. Ubukhulu becala iqulunqwe luthungelwano nothungelwano losasazo.

Zonke izixhobo zothumelo lwamandla kunye nezixhobo zenguqu zidityanisiwe ukuze zenze uthungelwano lothumelo, kwaye zonke izixhobo zokusasaza kunye nenguqu zidityanisiwe ukwenza inethiwekhi yokuhambisa. Uthungelwano lothutho lwamandla lubandakanya ukuhanjiswa kwamandla kunye nezixhobo zenguqu. Izixhobo zokuhambisa amandla ikakhulu zibandakanya ii-conductors, iingcingo eziphantsi komhlaba, iinqaba, iintambo zokhuselo, iintambo zombane, njl.njl.; izixhobo zokuguqula umbane zibandakanya ii-transformers, ii-reactors, ii-capacitors, ii-circuit breakers, i-grounding switching, ukwahlula izitshixo, izibambi zombane, ii-voltage transformers, ii-transformers zangoku, ii-busbar, njl njl. uthumelo, ukujonga, ulawulo kunye neenkqubo zonxibelelwano lwamandla. Izixhobo zenguqu zigxininiswe ikakhulu kwizitishi. Ulungelelwaniso lwezixhobo eziphambili kunye nezixhobo zesibini ezinxulumeneyo kuthungelwano lothumelo lubalulekile ekusebenzeni okukhuselekileyo nozinzo lwesixokelelwano samandla kunye nokuthintela iingozi zamatyathanga kunye nokumka kombane okukhulu.

Iintambo zombane ezithwala umbane ukusuka kumaziko ombane ukuya kumaziko okulayisha kunye nokudibanisa iinkqubo zamandla ezahlukeneyo zibizwa ngokuba ziintambo zothumelo.
Imisebenzi yeentambo zothumelo ibandakanya:
(1) ''Ukuhanjiswa kwamandla'': Owona msebenzi uphambili weentambo zothumelo oluphezulu kukuthutha umbane ukusuka kwizibonelelo zokuvelisa umbane (ezifana namaziko ombane okanye izikhululo zamandla ahlaziyekayo) ukuya kwizitishi ezikude kunye nabasebenzisi. Oku kuqinisekisa unikezelo lwamandla oluthembekileyo ukuhlangabezana neemfuno zemisebenzi yezentlalo nezoqoqosho.
(2) ''Ukuqhagamshela oomatshini bombane kunye nezikhululo ezincinci'': Iintambo zothumelo ezihamba phezulu ziqhagamshela ngokufanelekileyo oomatshini bombane abahlukeneyo kunye nezitishi ezincinci ukwenza inkqubo yombane emanyeneyo. Olu xhulumaniso lunceda ukufezekisa ukuxhaswa kwamandla kunye nokucwangciswa okufanelekileyo, ukuphucula ukusebenza kakuhle kunye nokuzinza kwenkqubo.
(3) ''Ukukhuthaza ukutshintshiselana nokusasazwa kwamandla'': Iintambo zothumelo oluphezulu zinokudibanisa iigridi zamandla zamanqanaba ombane ahlukeneyo ukuze kuqatshelwe ukutshintshiselwa kwamandla kunye nokusasazwa phakathi kwemimandla eyahlukeneyo kunye neenkqubo. Oku kunceda ukulungelelanisa unikezelo kunye nemfuno yenkqubo yamandla kunye nokuqinisekisa ukuhanjiswa okufanelekileyo kombane.
(4) ''Yabelana ngomthwalo wencopho yombane'': Ngexesha lokusetyenziswa kombane ophakamileyo, iintambo zokuhambisa umbane ongaphezulu zinokuhlengahlengisa usasazo lwangoku ngokweemeko zokwenyani ukuze zabelane ngokufanelekileyo umthwalo wombane kwaye zithintele ukugcwala kakhulu kwezinye iintambo. Oku kunceda ukuqinisekisa ukusebenza okuzinzile kwenkqubo yamandla kwaye ugweme ukucima umbane kunye nokungasebenzi kakuhle.
(5) ''Ukomeleza uzinzo nokuthembeka kwenkqubo yamandla'': Uyilo nokwakhiwa kweentambo zothumelo oluphezulu ludla ngokuqwalasela iimeko ezahlukeneyo zokusingqongileyo kunye neemeko zokusilela ukuqinisekisa uzinzo nokuthembeka kwenkqubo yamandla. Umzekelo, ngokumiselwa komgca ofanelekileyo kunye nokukhethwa kwezixhobo, umngcipheko wokungaphumeleli kwenkqubo unokuncitshiswa kwaye amandla okubuyisela inkqubo anokuphuculwa.
(6) ''Khuthaza ulwabiwo olulolona luphezulu lwezibonelelo zamandla'': Ngokusetyenziswa kweentambo zothumelo oluphezulu, imithombo yombane inokwabelwa ngokupheleleyo kuluhlu olukhulu ukuphumeza ukulingana phakathi kobonelelo lwamandla kunye nemfuno. Oku kunceda ekuphuculeni impumelelo yokusetyenziswa kobutyebi bamandla kunye nokukhuthaza uphuhliso loqoqosho oluzinzileyo.
