Ulawulo lomthwalo:

Iisokethi zekhebula eziphezulu ze-voltage ziyakwazi ukusasaza amandla ukusuka kwimithombo eyahlukeneyo ukuya kwiindawo ezininzi, okuvumela ukulawula ngokufanelekileyo umthwalo kunye nokusebenza kakuhle kwegridi.

Iimpawu eziphambili zeesokethi zentambo zombane ophezulu:

Ukuqinisekisa ukuhanjiswa kwamandla okuthembekileyo kunye nokusebenza kakuhle, iisokethi zentambo ezinombane ophezulu zineempawu ezininzi ezisisiseko. Ezi mpawu zikwandisa ukusebenza kunye nokhuseleko lwenkqubo yonke yamandla.

Ezinye iimpawu eziphambili ziquka:

Umlinganiselo woMbane oPhezulu:

Izixhobo zentambo zombane ophezuluziyilelwe ukuphatha amanqanaba ombane aphezulu, aqala ukusuka kuma-66 kV ukuya kuma-500 kV nangaphezulu, ukuqinisekisa ukuhanjiswa kwamandla okukhuselekileyo nokusebenzayo.

Ulwakhiwo olumagingxigingxi:

Ezi zakhiwo zakhiwe ukuba zimelane neemeko ezinzima zokusingqongileyo, kubandakanywa amaqondo obushushu agqithisileyo, ukufuma, kunye nokuvezwa kweekhemikhali, ukuqinisekisa ukuthembeka kwexesha elide kunye nokuqina.

I-Insulation kunye nokuKhusela:

Iisokethi ze-cable high-voltage zisebenzisa i-insulation kunye nezixhobo zokukhusela ukukhusela ukuvuza kunye nokuqinisekisa ukuhanjiswa okukhuselekileyo kwamandla, ukunciphisa umngcipheko weengozi zombane kunye nobungozi.

Ukubona iimpazamo kunye neempawu zokhuseleko:

Ezinye iisokethi zekhebula eziphezulu ze-voltage zixhotyiswe ngeenkqubo zokubona iimpazamo ezinokukhawuleza zichonge kwaye zihlukanise naziphi na iimpazamo zombane, ukwandisa ukhuseleko kunye nokunciphisa ixesha lokunciphisa.

Ukuphucula ukuhanjiswa kwamandla:

Iisokethi zekhebula eziphezulu ze-voltage zidlala indima ebalulekileyo ekuphuculeni ukusebenza kakuhle kokuhanjiswa kwamandla. Uyilo olusebenzayo kunye nokusebenza kunceda ukufezekisa ezi njongo zilandelayo:

Nciphisa ilahleko yamandla:

Iisokethi zekhebula eziphezulu, ukuba zifakwe kwaye zigcinwe ngokuchanekileyo, zinokunciphisa ukulahlekelwa kwamandla ngexesha lokuhanjiswa, ukuqinisekisa ukunikezelwa kwamandla okusebenzayo kunye nokunciphisa inkunkuma yamandla ngokubanzi.

Ukuthembeka kwenkqubo ephuculweyo:

Izixhobo ezinokwethenjelwa ezithembekileyo ze-cable high-voltage zinceda ukwandisa ixesha lenkqubo ngokuthintela iimpazamo zombane kunye nokungaphumeleli, ukunciphisa ixesha lokunciphisa kunye nokwandisa ukuthembeka kwenethiwekhi yokusabalalisa amandla. Ukukhuthaza ukudityaniswa kwamandla ahlaziyekayo kwigridi: Iziseko zekhebula eziphezulu ze-voltage zidlala indima ebalulekileyo ekudityanisweni kwamandla avuselelekayo kwigridi. Ngokuqhagamshela izixhobo zokuvelisa amandla ahlaziyekayo kwigridi, ezi sokethi zenza ukuba kusetyenziswe ngokufanelekileyo amandla acocekileyo nazinzileyo.

ukuququmbela:

Izixhobo zentambo zombane ophezuludlala indima ephambili ekuboneleleni ngokukhuselekileyo nangokufanelekileyo ukuhanjiswa kwamandla kumgama omde. Ezi ndawo zokuthengisa zinemilinganiselo ephezulu yombane, ulwakhiwo olurhabaxa, kunye neempawu eziphambili zokuqinisekisa ukuthembeka, ukunciphisa ilahleko yamandla, kunye nokwandisa ukusebenza kakuhle kokuhanjiswa kwamandla. Njengoko ukuqhubela phambili kwezobuchwepheshe kuqhubeka nokubumba imboni yamandla, iisokethi zekhebula eziphezulu zombane ziya kuhlala ziyingxenye ebalulekileyo, zibonelela ngokubonelela ngombane okuzinzileyo, okuthembekileyo kwizicelo ezahlukeneyo.
