Submerged arc furnace-electric arc wan wut (sh) wan n-gun hpe ninghkap ai wan wut- ngu nna mung shamying ai, madung hku nna nhprang wan n-ga, carbonaceous shayawm ai arung arai ni, fluxes zawn re ai n-gun shayawm ai arung arai ni hpe shayawm ai hku n-gun shayawm ai hta jai lang ai. Dai gaw, nhprang dat (hpyen nhprang dat, nhprang dat, nhprang dat, nhprang dat, nhprang dat zawn re ai) hte calcium carbide zawn re ai tsi mawan ni hpe galaw shapraw na matu ahkyak ai hpaga lam arung arai langai rai nga ai.
Dai wan wut gaw carbonaceous (sh) magnesia n-gun n rawng ai shingnip hte self-wan wut ai electrode ni hpe lang nna bungli galaw ai. Shi gaw, hka kata de lup ai -arc operation-dai hta electrode ni hpe wan wut charge- hta bang da ai matut manoi galaw ai lam hku nna bungli galaw nna, arc n-gun hte resistance heating (charge hku nna current lai wa ai shaloi byin pru wa ai) lahkawng yan hpe jai lang nna, magri hpe manam pyaw hkra galaw ai; charge galaw ai hpe matut manoi galaw ai, n-gun rawng ai magri hte slag hpe tapping galaw ai gaw aten kadun laman byin ai. Dai wan wut hpe daw jau ai transformer gaw matut manoi, ngang grin ai n-gun npu hta bungli galaw nna, n-gun n law ai n-gun, n-gun law law hpe kaji kajaw jat ai hte n-gun hpe hkang ai lahkam law law, n-gun grai law ai n-gun hpe hkam la lu ai atsam nga ai. Ndai transformer ni hpe on-load n-gun hpe hkang ai hte off-circuit (no-excitation) n-gun hpe hkang ai ngu ai lahkawng hku nna mai lang ai. Kaja wa nga yang, shanhte gaw shawng nnan na voltage lahkam ni hta n galai shai ai power pru ai lam hpe jaw ya nna, hpang na lahkam ni hta n galai shai ai current pru ai lam hpe jaw ya ai.
