Saldhiga dahaarka eeIska caabinta WirewoundDabaylaha silig iska caabbinta ah waxay caadi ahaan u isticmaalaan dhoobada aluminium oxide sida saldhigga dahaarka.Dabaylaha tamarta yar, ulaha dhoobada adag ayaa si caadi ah loo isticmaalaa, halka dabaylaha awooda sare leh ay isticmaalaan ulo daboolan oo bannaan.Farqiga tayada ee walxaha salka ayaa si weyn u saameeya kuleylka kuleylka iyo waxqabadka korantada ee iska caabiyeyaasha.
Qalabka koofiyadaha eeIska caabinta Wirewound: Waxaa jira dhowr nooc oo ah agabka daboolka, oo ay ku jiraan varnish dahaarka, dhaldhalaalka silikoon resin walxo isku dhafan, balaastig, dhoobo, iyo daasad aluminium ah.Dahaarka dahaarka ayaa ah sheyga ugu dhaqaalaha badan, oo leh habsocod fudud oo ku lug leh dahaadhka xadhigga caabbinta hore ee boogta ee salka iyo qalajinta heerkulka hooseeya.Iyadoo ay bixiso waxqabadka dhexdhexaadinta dhexdhexaadka ah, waxay leedahay saameyn xaddidan oo ku saabsan kuleylka kuleylka ee resistor, taas oo ka dhigaysa mid ku habboon codsiyada heerkulka hooseeya iyo kuwa hooseeya.
Resistor Wire eeIska caabinta Wirewound: Doorashada walxaha siligga ayaa si toos ah u go'aaminaya isku-dhafka heerkulka, qiimaha iska caabinta, awoodda culeyska muddada-gaaban, iyo xasilloonida muddada dheer ee caabiyaha.Daawaha nickel-chromium waa alaabta siliga ah ee inta badan la isticmaalo, laakiin tayada iyo hababka wax soo saarku aad bay ugu kala duwan yihiin soo saarayaasha fiilooyinka kala duwan, taas oo horseedaysa kala duwanaansho ka kooban walxaha raadraaca ee daawaha.Qalabka tayada sare leh ayaa muujinaya isbeddelada ugu yar ee waxqabadka korantada inta lagu jiro heerkulka sare ee sintering, hubinta xasilloonida.Iska caabiyeyaasha ku dhaawacmaan darajooyinka kala duwan ee walxaha siligga ee isla cabbirka saldhigga waxay keeni karaan kala duwanaansho la taaban karo oo qiyamka caabiga ah.Tani waxay sharraxaysaa sababta soo-saareyaasha waddanku ay inta badan u soo saaraan resistors ee kala duwanaanshaha kilo-ohm, halka soo-saareyaasha ajnabiga ah ay ku guuleysan karaan iska caabbinta boqollaal kilo-ohms ama xitaa tobanaan mega-ohms oo isku mid ah qiimeynta awoodda.Qiimaha iska caabinta kala duwan iyo qiimeynta korantadu waxay u baahan yihiin xulashada cabbirada siliga kala duwan.
