Oloa Fa'amatalaga
O le eletise e ave le eletise e faʻavela ai ogaumu arc eletise, o le tele o ogaumu uʻamea. E faia mai le suau'u coke pe a mae'a fa'afefiloi ma petroleum pitch, extruded ma fa'apena, ona tao lea e fa'aluma ai, ona fa'apalapala lea e ala i le fa'avevelaina i luga a'e o le vevela (3000 °C) lea e liua ai le kaponi i le graphite. E mafai ona eseese i le lapopoa e oo atu i le 11 ft. umi ma le 30 inisi le lautele.
Fa'aoga
- 01 Ole fa'atuputeleina o le u'amea o le lalolagi o lo'o faia ile fa'aogaina o ogaumu arc eletise
- 02 O le ogaumu arc eletise lava ia ua sili atu ona lelei ma sili atu le uamea i le tone o le eletise
