1) Ho hanyetsa ha mokhanni oa koporo ke hoo e ka bang 60% feela ea mokhanni oa aluminium. E le ho finyella litlhoko tse tšoanang tsa tahlehelo le ho phahama ha mocheso, sebaka sa sefapano sa aluminium conductor se lokelang ho sebelisoa se feta 60% se seholo ho feta sa mokhanni oa koporo, kahoo matla a tšoanang le litekanyetso tse tšoanang Tlas’a maemo a tloaelehileng, aluminium conductor transformer hangata e kholo ho feta mochine oa motlakase oa koporo, empa ka nako ena sebaka sa ho senya mocheso sa transformer se boetse se eketseha, kahoo mocheso oa eona o nyolohela ho oli o tlaase;

2) Boima ba aluminium ke hoo e ka bang 30% feela ea koporo, kahoo mochine oa aluminium conductor distribution transformer o bobebe ho feta mochine oa ho tsamaisa mochine oa koporo;

3) Sebaka sa ho qhibiliha sa li-conductors tsa aluminium se tlase haholo ho feta sa li-conductor tsa koporo, ka hona moeli oa eona oa ho phahama ha mocheso ka nako e khutšoanyane ke 250 ° C, e leng e ka tlaase ho ea li-conductor tsa koporo ka 350 ° C, ka hona, sebopeho sa eona ke XNUMX ° C. e tlase ho feta ea li-conductor tsa koporo, ‘me sebaka sa marang-rang sa lithapo tsa motlakase se seholoanyane. E kholo, kahoo molumo o boetse o moholo ho feta mochine oa motlakase oa koporo;

4) Boima ba mokhanni oa aluminium bo tlaase, kahoo li-burrs tsa eona li bonolo ho li felisa, kahoo ka mor’a hore transformer e etsoe, monyetla oa hore ho be le li-inter-turn kapa inter-layer short circuit e bakoang ke burrs e fokotsehile;

5) Ka lebaka la matla a tlaase le a ho hatella le matla a fokolang a mochine oa aluminium conductor, matla a nakoana a aluminium conductor transformer ha a tšoane le a koporo ea koporo ea koporo. Ha ho baloa botsitso bo matla, khatello ea mokhanni oa aluminium e lokela ho ba tlase ho 450kg / cm2, ha mochine oa koporo Moeli oa khatello ea mokhanni ke 1600kg / cm2, ‘me matla a ho jara a ntlafatsoa haholo;

6) Ts’ebetso ea ho tjheseletsa pakeng tsa mokhanni oa aluminium le mokhanni oa koporo e futsanehile, ‘me boleng ba ho tjheseletsa ha lenonyeletso ha bo bonolo ho tiisa, bo amang ho tšepahala ha mokhanni oa aluminium ho isa tekanyong e itseng.
