Ukulinganisa kwangoku kwamacandelo eYurophu kuchongwa ngokubeka iliso kwiqondo lokushisa lomqhubi wesinyithi njengoko ukunyuka kwangoku kwanda.Xa ubushushu bepini yentsimbi bungama-45 °C ngaphezulu kobushushu be-ambient, abasebenzi bokulinganisa baya kusebenzisa okwangoku ngeli xesha njengexabiso elilinganisiweyo langoku (okanye ixabiso eliphezulu langoku) lesixhobo.Enye into yenkcazo ye-IEC yixabiso elivumelekileyo langoku, eliyi-80% yobuninzi bangoku.Ngokwahlukileyo, umgangatho we-UL uya kwenza iqondo lobushushu lentsimbi libe ngama-90% aphezulu kunobushushu be-ambient njenge-90% yexabiso langoku lesixhobo njengexabiso legama langoku lesixhobo.
Ingabonwa ukuba ubushushu becandelo lomqhubi wensimbi yinto ebaluleke kakhulu kuzo zonke izicelo.Oku kubaluleke ngakumbi kwizixhobo zamashishini.Kuba izixhobo zemizi-mveliso zidla ngokufuna ukusebenza kwindawo enamaqondo obushushu ukuya kutsho kuma-80 °C.Ukuba ubushushu bebhloko ye-terminal yi-30 ° C okanye i-45 ° C ngaphezu kolu bushushu, iqondo lokushisa le-terminal liya kudlula i-100 ° C. Ngokuxhomekeke kuhlobo lwexabiso eliqhelekileyo kunye ne-insulation esetyenziswe kwisixhobo esikhethiweyo, imveliso kufuneka isebenze. kumgangatho ongaphantsi kunokalo lwangoku ukuqinisekisa ukusebenza okuthembekileyo kuluhlu olufunekayo lobushushu.Ngamanye amaxesha izinto ezifanelekileyo kwi-compact package devices zingakwazi ukuhlangabezana neemfuno ze-thermal kakuhle, ngoko ke i-current esetyenziswa kwizixhobo ze-terminal kufuneka ibe ngaphantsi kakhulu kunexabiso elilinganisiweyo.Ngale ndlela, ukubaluleka kwendlela yokukhetha uhlobo lwe-terminal lubonakaliswe.Njengoko iinkampani zisiba ngakumbi kwihlabathi, kufuneka zenze iinkqubo ezinokuthengiswa kwihlabathi liphela, ngoko ke abaqulunqi benkqubo baya besebenzisa iimveliso zesiphelo eziveliswa kwamanye amazwe.Ekubeni iYurophu isebenzisa iindlela zokulinganisa okuqhelekileyo, kuyinto eqhelekileyo eYurophu ukusebenzisa izixhobo ezingaphantsi kwexabiso eliqhelekileyo kuyilo.Nangona kunjalo, abaninzi abaqulunqi baseMelika abaqhelananga nale ngcamango, kwaye ukuba awuqondi umahluko phakathi kwemigangatho, kuya kuba nzima kwinkqubo yoyilo.
