Ngokubanzi, i-busbar ephakathi kwesiphelo semveliso yekhabhinethi ye-DC graphitization furnace rectifier kunye ne-electrode eqhubayo yentloko ye-furnace ibizwa ngokuba yi-short net, kwaye i-busbar esetyenziswa kwi-graphitization furnace idla ngokuba yi-rectangular. I-busbar ye-graphitization furnace yenziwe nge-copper kunye ne-aluminium. I-Copper inamandla aphezulu oomatshini, i-conductivity yombane elungileyo kunye nokumelana okunamandla kokugqwala. I-aluminium ayiqhubi kakuhle, kodwa i-aluminium ixabisa kancinci kwaye inobunzima obuphantsi.
Itheyibhile 3-2 Idatha yokusebenza efanelekileyo yobhedu kunye ne-aluminium
| 材 料 | 比重 | 极限强度(MPa) | 电阻率(µΩm) | 电阻的温度系数(1/℃） |
| 紫 铜 | 8.9 | 220 | 0.016 | 4.3×10-3 |
| 铝 | 2.7 | 110 | 0.025 | 4.7×10-3

Ekubeni ukumelana kwesithando somlilo se-graphitization kuncinci, ingakumbi kwinqanaba lokugqibela lokudluliselwa kwamandla, ukumelana kwesithando somlilo kuba kuncinci, kwaye ukuhla koxinzelelo lwe-short net kuyanda, okubangela ukwanda kokulahleka kwamandla. Ke ngoko, ukuba isithando somlilo se-graphitization singasebenza ngokukhuselekileyo nangokwezoqoqosho, sinolwalamano olusondeleyo neempawu ze-short net.
Umgaqo osisiseko kukunciphisa ukungakwazi ukuthintela i-nethi emfutshane kwaye ugcine i-nethi emfutshane yonke ngokunciphisa uxinzelelo oluncinci. Kukho oonxibelelwano abahlukeneyo kwi-mesh emfutshane yesithando se-graphitization. Ukuba kukho unxibelelwano phakathi kwe-electrode eqhubayo kunye nebhasi yobhedu, unxibelelwano phakathi kwebhasi ethambileyo yobhedu kunye nebhasi ye-aluminium, unxibelelwano phakathi kwebhasi ye-aluminium, njl.njl., olu nxibelelwano luya kuvelisa ukumelana noqhagamshelwano, luchaphazela iimpawu ze-nethi emfutshane yonke. Ukumelana noqhagamshelwano komqhubi onendawo yonxibelelwano akuxhomekanga kuphela kuhlobo lwezinto, kodwa nakwindawo yoqhagamshelwano kunye noxinzelelo loqhagamshelwano ngexesha lonxibelelwano loqhagamshelwano. Ngenxa yesi sizathu, eyona isisiseko xa uqhagamshela ii-busbars kukuba: ukupolisha kuqinile.
