Rwb thaiv tsev Base ntawmWirewound Resistor: Resistor hlau windings feem ntau siv aluminium oxide ceramic ua lub hauv paus rwb thaiv tsev. Rau cov khoom siv hluav taws xob tsawg, cov khoom siv hluav taws xob ceramic feem ntau siv, thaum lub zog hluav taws xob muaj zog siv hollow rwb thaiv tsev rods. Qhov zoo sib txawv ntawm cov khoom siv hauv paus cuam tshuam rau cov cua sov dissipation thiab hluav taws xob ua haujlwm ntawm cov resistors.
Encapsulation Materials ntawmWirewound Resistor: Muaj ntau yam khoom siv encapsulation, xws li rwb thaiv tsev varnish, silicone resin enamel tov khoom, yas encapsulation, ceramic, thiab txhuas casing. Rwb thaiv tsev cov kua roj vanish yog cov khoom siv hluav taws xob zoo tshaj plaws, nrog rau cov txheej txheem kev thov yooj yim uas muaj cov txheej txheem ua ntej lub qhov txhab resistor hlau rau ntawm lub hauv paus thiab ziab kom qhuav. Thaum nws muaj kev ua haujlwm nruab nrab ntawm kev rwb thaiv tsev, nws muaj kev cuam tshuam tsis zoo rau cov cua kub dissipation ntawm cov resistor, ua rau nws tsim nyog rau kev siv qis-kub thiab tsis tshua muaj kev ntseeg siab.
Resistor Hlau ntawmWirewound Resistor: Kev xaiv ntawm cov khoom siv hlau ncaj qha txiav txim siab qhov ntsuas kub coefficient, tus nqi tiv thaiv, lub sijhawm luv luv overload muaj peev xwm, thiab kev ruaj ntseg ntev ntawm cov resistor. Nickel-chromium alloy yog cov khoom siv hlau feem ntau siv, tab sis cov txheej txheem zoo thiab kev tsim khoom sib txawv heev ntawm cov tuam txhab hlau sib txawv, ua rau muaj qhov sib txawv ntawm cov kab hauv cov hlau. Cov khoom siv hlau zoo muaj qhov hloov pauv me me hauv kev ua haujlwm hluav taws xob thaum lub sijhawm kub kub sintering, ua kom ruaj khov. Resistors raug mob nrog cov qib sib txawv ntawm cov khoom siv hlau ntawm tib lub hauv paus loj tuaj yeem ua rau muaj kev hloov pauv loj hauv cov txiaj ntsig tsis kam. Qhov no piav qhia tias vim li cas cov tuam txhab lag luam hauv tsev feem ntau tsim cov resistors hauv kilo-ohm ntau, thaum cov tuam txhab txawv teb chaws tuaj yeem ua tiav qhov kev tawm tsam ntawm ntau pua kilo-ohms lossis txawm kaum ntawm mega-ohms rau tib lub zog ntsuas. Qhov sib txawv kuj tseem ceeb thiab kev ntsuas hluav taws xob xav tau kev xaiv ntawm cov kab ntsuas sib txawv.
