Aluminium Resistorsthiab Cement Resistors yog nyob rau tib qeb ntawm wirewound resistors, tab sis tsis muaj qhov sib txawv ntawm Aluminium Resistors thiab Cement Resistors kom deb li deb raws li tus nqi tiv thaiv.Cement resistors yog wirewound resistors kaw nrog xis mas, piv txwv li, lub resistor hlau yog qhov txhab ntawm cov khoom uas tsis yog-alkaline tshav kub-resistant ceramic qhov chaw, sab nraud yog ntxiv nrog kub-, noo noo-, thiab corrosion-resistant cov ntaub ntawv rau kev tiv thaiv thiab kho, thiab lub wirewound resistor lub cev yog muab tso rau hauv ib tug square ceramic thav duab, uas yog sau thiab kaw nrog ib tug tshwj xeeb uas tsis yog-combustible kub-resistant cement.Sab nrauv ntawm cement resistor yog tsim los ntawm ceramic.Muaj ob hom cement braking resistors: zoo tib yam cement resistors thiab talc porcelain cement resistors.
Los ntawm lub hwj chim taw tes ntawm view, lub hwj chim ntawm lubaluminium vaj tse resistortuaj yeem ua kom loj dua, tab sis cov cement resistor tsuas tuaj yeem ua tau txog li 100W.Aluminium vaj tse resistor belongs rau lub zog siab dua resistor, uas muaj peev xwm tso cai rau cov dej ntws loj dua.Nws lub luag haujlwm yog tib yam li cov resistor dav dav, tshwj tsis yog tias nws tuaj yeem siv rau lub sijhawm muaj kev kub ntxhov, xws li hauv series nrog lub cev muaj zog los txwv qhov pib tam sim no ntawm lub cev muaj zog, tus nqi kuj feem ntau tsis loj.Cement resistors muaj cov yam ntxwv ntawm qhov me me, kev poob siab tsis kam, noo noo tsis kam, kub tsis kam thiab zoo cua sov dissipation, tsis tshua muaj nqi, thiab lwm yam. Lawv tau siv dav hauv cov khoom siv fais fab, cov khoom siv suab, suab crossovers, twj paj nruag, meters, TV, tsheb thiab lwm yam. khoom siv.
Los ntawm qhov pom ntawm kev ua kom sov dissipation, ua kom yooj yim piv txwv,aluminium vaj tse resistorsyog sib npaug rau cov cua txias, thiab cov cement resistors sib npaug rau cov kiv cua.Aluminium plhaub thermal kev ua tau zoo yog qhov zoo, overload tuaj yeem ua kom txias raws sijhawm, kom qhov ntsuas kub tsis ncav cuag qhov siab heev, nyob rau hauv ib qho kev sib txawv, tus nqi kuj tsis hloov, thaum lub cement resistor txias yuav ua rau me ntsis zuj zus.Thaum lub sij hawm tsim cov txheej txheem, cov khoom siv hauv tsev aluminium kuj tau nruab nrog cov khoom siv cement tshwj xeeb sab hauv, qhov sib txawv yog tias ib qho sab nraud yog aluminium alloy, ib qho sab nraud yog plooj (porcelain).
