 Umgaqo ophambili

I-Zno ukukhanyisa i-assteris luhlobo olunye lwegama eliphambili ngaphezulu kwe-vllage protector atpresont.duo kwizinto zayo ezingundoqo zokumelana nokusebenzisa i-Zno kunye nezinye i-oxide zentsimbi ukwenza i-ot. Xa kuthelekiswa ne-carborundum arester, iyayiphucula kakhulu i-V-Acharacteristicsof reistance, inciphisa amandla okufumana amandla okuxhathisa, ngaloo ndlela izisa utshintsho olusisiseko kwiimpawu zerrester.
Ngaphantsi kwesiqhelo se-vllag. I-arester kuphela ngenxa yokuvota ngaphezulu
