Ngokuvamile, i-busbar ephakathi kokuphela kokukhipha kwekhabhinethi yokulungisa i-DC graphitization furnace kanye ne-electrode eqhubayo yekhanda lesithando ibizwa ngokuthi i-short net, kanti i-busbar esetshenziswa esithandweni se-graphitization ngokuvamile iyi-rectangular. I-busbar yesithando se-graphitization yenziwe ngethusi ne-aluminium. Ithusi linamandla aphezulu okusebenza, liqhuba kahle ugesi futhi limelana nokugqwala okunamandla. I-aluminium ayiqhubi kahle, kodwa i-aluminium ishibhile futhi inesisindo esilula.
Ithebula 3-2 Idatha yokusebenza efanele yethusi 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

Njengoba ukumelana kwesithando somlilo se-graphitization kuncane, ikakhulukazi esigabeni sokugcina sokudluliswa kwamandla, ukumelana kwesithando somlilo kuba kuncane, futhi ukwehla kwengcindezi ye-short net kuyakhuphuka, okuholela ekwandeni kokulahlekelwa kwamandla. Ngakho-ke, ukuthi isithando somlilo se-graphitization singasebenza ngokuphepha nangokwezomnotho yini kunobuhlobo obuseduze nezici ze-short net.
Isimiso esiyisisekelo kakhulu ukunciphisa ukuvinjelwa kwenethi elifushane nokugcina inethi elifushane lonke ngokuncipha okuncane kwengcindezi. Kunezindlela ezahlukahlukene zokuxhumana ku-mesh emfushane yesithando se-graphitization. Uma kukhona ukuxhumana phakathi kwe-electrode eqhubayo nebhasi lethusi, ukuxhumana phakathi kwebhasi elithambile lethusi nebhasi le-aluminium, ukuxhumana phakathi kwebhasi le-aluminium, njll., lezi zindlela zokuxhumana zizokhiqiza ukumelana kokuxhumana, kuthinte izici zenethi elifushane lonke. Ukumelana kokuxhumana komqhubi onendawo yokuxhumana akuxhomekile kuphela ohlotsheni lwezinto ezibonakalayo, kodwa futhi nasendaweni yokuxhumana kanye nengcindezi yokuxhumana ngesikhathi sokuxhumana. Ngenxa yalesi sizathu, eyisisekelo kakhulu lapho uxhuma amabhara yilokhu: ukupholisha kuqinile.
