Dielectric (insulator) waa mid ka mid ah kharashyada togan iyo kuwa taban ee hoos yimaada ficilka beerta korantada ee polarization ugu weyn ee fasalka qalabka.Farqiga band dielectric E waa weyn yahay (ka weyn 4eV), electrons ee band valence waa adag tahay in ay u gudbaan band conduction, eegi waa in xaalad xaddidan, sidaas darteed waxa kaliya ee polarized karaa beerta korontada, adag tahay in ay ka qayb qaataan. ku dhaqan.

Ujeedada go'doominta kirishbooyada ee awoodo kala duwan iyo xaddidaadda socodka hadda ee qalabka korantada iyo elektiroonigga ah waxaa lagu gaari karaa iyadoo la isticmaalayo dahaarka korantada ee dielectric.Sidaa darteed, alaabta dahaarka waxay leeyihiin sifooyinka xoogga burburka sare iyo caabbinta mugga iyo tanδ hooseeya.Codsiga, waxaa badanaa loo baahan yahay in lagu ciyaaro doorka taageerada farsamada iyo hagaajinta, kuleylka kuleylka iyo qaboojinta, bakhtiinta arc iyo wixii la mid ah.Marka dielectric loo isticmaalo walxo shaqaynaysa korantada, kuma koobna guryaha korantada, laakiin waxay isticmaashaa sifooyinkeeda kala duwan.Iyadoo horumarinta tignoolajiyada sare, dielectric functional si degdeg ah u horumariyo oo waxaa loo isticmaalaa in ka badan iyo aad u ballaaran.

Waa in la ogaadaa in sifooyinka korantada ee walxaha dahaadhka ah ay si dhow ula xiriiraan xaaladaha deegaanka, guud ahaanna looma isticmaali karo inay matalaan waxqabadka dhammaan kala duwanaanta shaqada oo leh waxqabadka lagu qiyaasay hal xaalad wareeg ah.Intaa waxaa dheer, hababka tijaabada ah waxay leeyihiin saameyn xooggan oo ku saabsan qiyamka la qiyaasay ee sifooyinka alaabta.

Hal qayb oo ka mid ah Jiujiang Xinxing Insulation Materials Co.,Ltdhorumariyo oo soo saara noocyo kala duwan oo ah laminates maro galaas epoxy, si weyn loogu isticmaalo korontada, korontadawarshadaha sida qaybo qaab-dhismeedka dahaarka, iwm, oo leh guryaha wanaagsan ee makaanikada iyo korantadashirkadu waxay soo saartay waxqabadka sare, heerkulka sare u adkaysta, qalabka dielectric sarewaxaa si weyn loo isticmaalaa in isgaarsiinta 5 g, baabuurta tamarta cusub, gaadiidka tareenka, substation weyn transformer, set dhalin weyn, tamarta nukliyeerka, koronto dabaysha, iyo beeraha kale, qalab isku dhafan multifunctional is-horumariyay in warshadaha difaaca, duulista iyo aerospace warshadaha, gargaarka masiibooyinka iyo meelo kale.
