1. Motsoako o Phethahetseng oa Matla le ho Tiea bakeng sa Tikoloho e Rarahaneng
- Ka lithapo tsa tšepe tse matla haholo e le karolo ea mantlha, mokhanni o ithorisa ka matla a ikhethang a ho tsitlella le ho hanyetsa mokhathala, a sebetsana habonolo le maemo a thata a kang ho tšela nako e telele, meea e matla le leqhoa/lehloa. E fokotsa mathata a ho oa ha mola, e fokotsa bothata ba ho emisoa le tlhokomelo.
- Likhoele tsa motsoako oa aluminium tse ka ntle li kopanya ho tiea ha tšepe le botsitso ba sebopeho, li fana ka khanyetso e phahameng ea mafome le khanyetso ea botsofali. Sena se eketsa bophelo ba ts'ebeletso ea mokhanni le ho fokotsa litšenyehelo tsa ts'ebetso ea nako e telele.

Li-conductor tsa Aluminium tse nang le Metsi a Tšepe: Tšehetso ea Phetiso ea Matla Maemong a Fapaneng
Ka melemo ea eona e kopaneng ea "matla a phahameng, ho tsamaisa motlakase hantle, le ho hanyetsa tikoloho," li-conductor tsa alloy tsa aluminium tse nang le tšepe li sebetsa e le sebapali sa bohlokoa phetisong ea motlakase masimong a mangata, li fana ka litharollo tse etselitsoeng maemo a fapaneng.
1. Khetho ea mantlha bakeng sa mela ea phetisetso ea motlakase o mahareng le o phahameng
Ka marangrang a mahareng le a phahameng a 110kV ho isa ho 500kV, di-conductor tsa alloy tsa aluminium tse nang le mothapo wa tshepe di ipabola e le "methapo e meholo" e hokahanyang di-substation le di-grid tsa dibaka.

2. Tšehetso e Tšepahalang bakeng sa ho Tšela Lithaba Tse Telele
Ha ho namela mekoallo ea tlhaho (linōka, likhohlo, lithaba) kapa litsela tsa bohlokoa tsa lipalangoang (litsela tse potlakileng, literene), matla a phahameng a li-conductor tsena a fokotsa tlhoko ea li-pylon tse ngata, a fokotsa mathata a ho oa a bakoang ke mekhahlelo e telele, 'me a netefatsa ts'ebetso e tsitsitseng tlas'a meea e matla, ho feto-fetoha ha mocheso le maemo a mang a thata. Li sebelisoa haholo meleng ea phetisetso ea linōka le mererong ea lithaba e holimo.
3. Ntlafatso le Ntlafatso ea Ligridi tsa Motlakase tsa Metseng le Mahaeng
