Thumela i-imeyileIntambo ye-Aluminiyam Concentric ifanelekile kwiindawo zokuhlala, zorhwebo kunye nemizi-mveliso, kubandakanya indawo yokungena kwisakhiwo, iisekethe ze-feeder kunye neesekethe zamasebe. Intambo ye-concentric isetyenziswa njengombaneumnyango wenkonzoukusuka kwinethiwekhi yokusasazwa kombane ukuya kwiphaneli yemitha (ingakumbi apho kufuneka khona ukuthintela ukulahleka "okumnyama" okanye ukuphangwa kombane), kwaye njengentambo yokuphakela ukusuka kwiphaneli yemitha ukuya kwiphaneli okanye kwiphaneli yokusasazwa ngokubanzi, njengoko kuchaziwe kwiKhowudi yoMbane yeSizwe. Olu hlobo lwekhontraktha lungasetyenziswa kwiindawo ezomileyo nezimanzi, ezingcwatywe ngqo okanye ngaphandle. Ubushushu bayo obuphezulu bokusebenza yi-90 ºC kwaye i-voltage yayo yenkonzo kuzo zonke izicelo yi-600V.
Iingenelo:
Ifanelekile ngokukodwa kwiintambo zonxibelelwano zesigaba esinye ezivela kwiintambo eziphezulu ezihlanganisiweyo kwangaphambili, i-voltage ephantsi, nto leyo enciphisa umngcipheko wokubiwa kwamandla. Ukufakelwa kufuna ukusetyenziswa kwee-air protections ezisebenza xa kukho i-short-circuit ngenxa yemizamo yokudibanisa efihlakeleyo, ephazamisa ukutya kwaye iveze ukuzama ukubiwa.
