● Izingxenye eziyinhloko ze-resistors zenziwe ngezinto ezivikelayo nezingashisi izinga lokushisa eliphezulu, njengohlaka lwama-resistors, amanxeba alinganayo ngezintambo ze-alloy zekhwalithi ephezulu. Igobolondo le-aluminiyamu lensimbi elifakwe ukufakwa okuphezulu kokunamathisela kwe-elekthronikhi okungashi, ukuze igobolondo le-aluminium kanye nezingxenye eziyinhloko zokumelana kuhlanganiswe eduze kube yinhlangano eqinile, engathinteki emoyeni wangaphandle, ukudlidliza nothuli, ngokuzinza okuphezulu kanye nokuhamba okushisayo.
● Igobolondo le-aluminium lenziwe nge-aluminium yezinga eliphezulu yezimboni engu-6063, futhi ingaphezulu linjalo
izinga lokushisa eliphezulu le-anodized ukuze kuzuzwe ukubukeka okukhangayo kanye nokuqeda ukushisa okukhulu.
● I-insulation isetshenziswa ngenqubo yezinga lokushisa eliphezulu.
