Sethula ukwakheka kwethu kwakamuva kwezokuphepha kwe-circuit breaker - idivayisi yokukhiya i-aluminium.Le divayisi yokukhiya yenziwe nge-alloy yekhwalithi ephezulu ye-aluminium ukuqina nokuthembeka okungenakuqhathaniswa.Ngokwelashwa kwe-oxidation engaphezulu, akugcini nje ngokuthuthukisa ukukhanga okuphelele kwemishini, kodwa futhi inokumelana nokugqwala okuqinile.
Idizayinelwe ukulingana namamodeli amaningi akhona ama-circuit breaker amancane e-Europe nase-Asia, amadivaysi ethu okuxhuma i-aluminium ayisixazululo esisebenza ngezindlela eziningi ezihlukahlukene zezinhlelo zokusebenza.Kungakhathaliseki ukuthi ungunjiniyela kagesi, uchwepheshe wezokulungisa noma othile ophathelene nokuphepha kwekhaya, le divayisi yokuvala ibalulekile ukuze uqinisekise ukuhlukaniswa okuphephile kwe-breaker circuit ngesikhathi sokulungisa noma sokulungisa.
