Lefatšeng la meralo ea motheo ea motlakase, litora tsa phetiso ea 500kV li bapala karolo ea bohlokoa ho netefatsa phetiso e nepahetseng le e tšepahalang ea motlakase libakeng tse telele. Litora tsena, tse tsejoang hape e le li-angle steel tower kapa lattice tower, li etselitsoe ho ts'ehetsa lithapo tsa motlakase tse nang le matla a phahameng, e leng se etsang hore e be karolo ea bohlokoa ea marang-rang a motlakase.

E 'ngoe ea likarolo tsa bohlokoa tsa litora tsa phetiso ea 500kV ke kaho ea tsona e sebelisang masenke. Boitsebiso bona bo fana ka litora ka matla le ho tšoarella ho hlokahalang ho mamella likarolo le ho tšehetsa mojaro o boima oa lithapo tsa motlakase. Sesete sena se boetse se sireletsa litora hore li se ke tsa bola, li lelefatsa bophelo ba tsona le ho netefatsa hore lithapo tsa phetiso tseo li li tšehetsang li lula li tšepahala.

Moralo oa litora tsa phetiso ea 500kV o entsoe ka hloko ho fihlela litlhoko tse ikhethileng tsa lithapo tsa motlakase tse phahameng. Hangata litora tsena li bitsoa litora tsa khatello, kaha li etselitsoe ho mamella tsitsipano ea mochini le matla a khatello a hlahisoang ke lithapo tsa motlakase. Ho feta moo, litora tse peli tsa potoloho li sebelisetsoa ho ts'ehetsa lihlopha tse peli tsa lithapo tsa motlakase, ho eketsa bokhoni le bokhoni ba lisebelisoa tsa phetisetso.

Ha ho tluoa ho moralo oa lithapo tsa phetiso ea 500kV, khetho ea mofuta o nepahetseng oa tora e bohlokoa. Sebopeho sa lattice sa litora tsena se fana ka matla a hlokahalang ha se ntse se fokotsa bongata ba thepa e hlokahalang, e leng se etsang hore e be tharollo e theko e tlaase bakeng sa ho tšehetsa lithapo tsa motlakase tse phahameng. Ho feta moo, moralo oa litora tsena o tlameha ho latela maemo a thata a boenjiniere ho netefatsa polokeho le ts'epahalo ea lits'ebetso tsa phetiso.

Bohlokoa ba litora tsa phetiso ea 500kV bo bonahala le ho feta ha ho nahanoa karolo eo li e bapalang moralong oa litsamaiso tsa likhoele tsa 500kV. Litsamaiso tsena li na le boikarabello ba ho fetisa motlakase o mongata libakeng tse telele, ho hokahanya lisebelisoa tsa ho fehla motlakase libakeng tsa baahi le libaka tsa indasteri. Moralo oa tsamaiso ea lithapo tsa phetiso, ho kenyeletsoa khetho le ho beoa ha litora, o bohlokoa ho netefatsa phano e nepahetseng le e tšepahalang ea motlakase ho bareki.

Qetellong, litora tsa phetiso ea 500kV ke karolo ea bohlokoa ea meralo ea motheo ea motlakase, e tšehetsang phetiso ea motlakase libakeng tse telele ka bokhabane le ka ts'epahalo. Kaho ea bona ea tšepe e entsoeng ka masenke, moralo oa tora ea strain, le karolo ho sistimi ea phetiso ea 500kV li li etsa tsa bohlokoa bakeng sa ho netefatsa botsitso le botsitso ba marang-rang a motlakase. Ha tlhoko ea motlakase e ntse e eketseha, bohlokoa ba litora tsena ho ts'ehetsa lithapo tsa phetisetso ea motlakase o phahameng bo ke ke ba fetisoa.
