● Izingxenye eziyinhloko ze-resistors zenziwe ngezinto ezivikelayo kanye nezingashisi eliphezulu ezimelana nezinga lokushisa njengohlaka lwe-resistors, zilimele ngokulinganayo ngezintambo ze-alloy zekhwalithi ephezulu.Igobolondo le-aluminiyamu yensimbi embozwe nge-insulation ephezulu yokunamathisela kagesi okungashi, ukuze igobolondo le-aluminium nokumelana izingxenye eziyinhloko zihlanganiswe eduze zibe yibhizinisi eliqinile, elingathinteki emoyeni wangaphandle, ukudlidliza nothuli, olunozinzo oluphezulu kanye ne-thermal conductivity.
● Igobolondo le-aluminium lenziwe nge-aluminium yezinga eliphezulu yezimboni engu-6063, futhi indawo engaphezulu inezinga lokushisa eliphezulu eligcotshwe nge-anod ukuze lifinyelele ukubukeka okukhangayo kanye nokukhishwa okukhulu kokushisa.
● I-insulation isetshenziswa ngenqubo yezinga lokushisa eliphezulu.
