Ephakamileyo-ubushushu obuguquguqukayo iNcingo eKhethiweyo:{1}}bunzulu uHlahlelo lwe-UL3512 iSilicone Wire

Kwimizi-mveliso, izixhobo ezitsha zamandla, izixhobo zombane eziphezulu-eziphezulu kunye neenkqubo zokukhanyisa, ukuxhathisa ubushushu, ukuguquguquka kunye nobomi beengcingo zimisela ngokuthe ngqo ukuzinza kwesixhobo. Intambo yentambo yomzi mveliso wethu i-UL3512, njenge-UL-eqinisekisiweyo yerabha yesilicone egqunywe phezulu{4}}ngocingo lobushushu, olunoluhlu olubanzi lobushushu obuphakathi -nobubanzi obungama-60 ukuya kuma-200, amandla ombane okalikiweyo angama-600V, kunye neempawu ezizodwa ezithambileyo nezibhetyebhetye, iye yaba yeyona nto iphambili ekukhetheni iqondo lobushushu obuphezulu. Eli nqaku liza kuhlanganisa iiparitha eziphambili, ukhetho lokuthelekisa, iimeko zesicelo, kunye namanqaku aphambili okukhetha, kukunceda uqonde ngokukhawuleza ukuba i-UL3512 ifanelekile kwiprojekthi yakho.

Loluphi uhlobo locingo UL3512? Iiparamitha ezingundoqo zicacile ngokukrwaqula.

I-UL3512 yeye-UL758 AWM enye{2}}yecingo lombane elingundoqo. Yenziwe ngerabha ye-silicone njengondoqo wokugquma, kwaye ixhotyiswe ngezikhondatha ezicekethekileyo ezininzi-ezixineneyo{5}}ezipleyitiweyo zekopolo. Yenzelwe ukusetyenziswa njengeingcingo zangaphakathi kunye nemigca yoqhagamshelo kwizixhobo zokusebenza ezifuna amaqondo obushushu aphezulu, ukuguquguquka, ukuxhathisa kwemozulu, kunye nokuncipha komlilo.

• Imigangatho kunye neziqinisekiso: UL758, CSA, ipasiswe i-VW-1/FT1 nkqo ukudeda komlilo

• Ixabiso lombane: 600V

• Ubushushu bokusebenza: -60℃ukuya +200 degree

• Izinto zokugquma: Irabha ye-Silicone (ezinye zinefiber yeglasi ephothiweyo ephothiweyo)

• I-Conductor: Multi{0}}i-strand fine ejijekileyo/eyodwa-inkcenkce ye-strand{2}}i-oksijini eplathiweyo{3}}ikopolo yasimahla, 0.3 ukuya kwi-250mm²

• Izinto eziphambili eziluncedo: Iguquguquka kakhulu kwaye iyagobeka, iyamelana namaqondo obushushu aphezulu naphantsi, ukumelana nokwaluphala, ioyile kunye neasidi kunye nealkali, umsi ophantsi kwaye-ayiyotyhefu.

• Imeko esebenzayo: Iingcingo zangaphakathi zezixhobo zombane ezivaliweyo, kufutshane nemithombo yobushushu obuphezulu{0}, kunye neeyunithi ezihlala zigotshwa kwaye zishukunyiswa.

Ayisiyo "inguqulelo ephuculweyo" eqhelekileyoPVC ucingookanyenqamleza-ngocingo oludityanisiweyo, kodwa isisombululo esizinikezele kwiimfuno ezimbini zokushisa okuphezulu kunye nokuguquguquka. Ayigugi ngexesha lokusebenza{1}}ixesha elide kwi-200℃kwaye ayiqini okanye iqhekeke kwi- -60℃. Lucingo oluyimfuneko lwezixhobo kumanqanaba obushushu obugqithisileyo.

Uthelekiso oluthe tyaba: UL3512 vs UL3173/3271/1015, yintoni umahluko?

Iinjineli ezininzi zithande ukubhida imifuziselo ye-UL yobushushu obuphezulu{0}} xa besenza ukhetho. Apha, sizithelekisa ngokuthe ngqo ukusuka kwimilinganiselo emihlanu: ubushushu, ukugquma, ukuguquguquka, ixabiso, kunye neemeko zesicelo ukuphepha ukwenza ukhetho olungalunganga.

Isiphelo: Kwi-125℃i-wiring esisigxina,3173/3271ixabiso- liyasebenza. Kwiisekethe ezimfutshane ngaphakathi kwezixhobo eziqhelekileyo zendlu,UL1015ingasetyenziswa kwizicelo zobushushu obuphezulu{2} apho kufuneka ufakelo oluguquguqukayo,UL3512inikeza iindleko eziphezulu{0}}ukusebenza kunye nokufakela ngokulula.

Eyona nto iluncedo kwi-UL3512: Kutheni ishishini liyithanda?

Ukusebenza okuzinzileyo ngaphakathi kwinqanaba lobushushu obugqithisileyo

Ayinyibiliki, ayiqhekeki okanye ikhukuliseke ekusebenzeni kokugquma emva kokubhaka ixesha elide-nge-200 degree. Ihlala ithambile kwaye ayiqhekeki kubushushu obuphantsi kakhulu-bu-60 degree, iyenza ilungele iingcingo zangaphandle emantla, izixhobo zokugcina ezibandayo, kunye neengcingo zangaphakathi kwiikhabhinethi ze-aerospace.

Ithambile kakhulu kwaye ibhetyebhetye kakhulu, kunye nobomi benkonzo yokugoba ixesha elide

Yamkela i-multi-i-strand ultra{1}}umtya ocolekileyo obambeneyo + ulwakhiwo olulastiki lwerabha yesilicone, kunye neradiyasi encinci yokugoba. Akulula ukuphula i-core kwaye i-insulation ayiyi konakaliswa nangemva kokugoba ngokuphindaphindiweyo, ukujija kunye nokudonsa. Kwizihlanganisi zerobhothi, iintambo zokutsalwa kweselula kunye nezixhobo zokuphakamisa, ixesha layo lokuphila lide kakhulu kunePVC kunye neeNcingo zeXLPE.

Idangatye-liyaliyeka kwaye lihambelana nokusingqongileyo, kunye nenqanaba eliphezulu lokhuseleko

Nge-UL VW{1}}1 ukutsha okuthe nkqo, kuyacima ngokwayo- xa isusiwe edangatyeni, ikhupha umsi ophantsi kwaye ayinayo ityhefu. Ihambelana ne-RoHS / REACH kwaye ifanelekile kwiimeko ezinokhuseleko oluphezulu kunye neemfuno zokukhusela okusingqongileyo ezifana nezixhobo zasekhaya, ukhathalelo lwezonyango, ukuhamba ngololiwe, kunye neekhabhinethi ezivaliweyo.

Imozulu-iyaxhathisa kunye nokwaluphala{1}}nokumelana nobomi obude benkonzo

Ayinyangeki nge-UV-i-ozone{1}}iyaxhathisa, i-oyile{2}}iyaxhathisa, i-asidi ne-alkali iyaxhathisa, kwaye iyaxhathisa ukufuma nobushushu{3}. Isantya sokuguga kwindawo yangaphandle nakwimizi-mveliso sicotha kakhulu kuneengcingo eziqhelekileyo, sicutha kakhulu amaxabiso emva{5}}wokutshintshwa kweentengiso.

Iimeko zesicelo eziphambili ze-UL3512

Amanqaku aphambili ukuphepha imigibe kukhetho lwe-UL3512 kunye nokuthengwa

1.Qinisekisa ukuba uyasiqonda isatifikethi se-UL ukunqanda isiqinisekiso somgunyathi kunye neentambo zokuqinisekisa ezisetyenziswa gwenxa. Ukubuyiswa komlilo okungafanelekanga kunye nokumelana nobushushu kunokubangela iingozi zokhuseleko.

2.Khetha imodeli esekelwe kwiqondo lokushisa langempela kunye ne-voltage: i-200℃/ 600V lixabiso eliqhelekileyo. Musa ukusebenzisa{4}}iingcingo zobushushu obuphakathi njengeendawo.

3.Ukugoba okuguquguqukayo kukhetha ngokukhethekileyo iikhondaktha ezininzi-ezijijekileyo zestrand, ngelixa iikondaktari ezinye zilungele iingcingo ezisisigxina.

4.Kummandla wangaphandle kunye ne-oyile, uguqulelo lwegilasi olulukiweyo oluqinisiweyo luyafumaneka, olunxibe kakhulu{1}} oluxhathisayo kwaye lukrazuka{2}}.

5.Umnqamlezo -ummandla wecandelo ubalwa ngokusekwe kwi-current and voltage drop. Kwiimekobume zobushushu obuphezulu-, idiameter yocingo kufuneka yandiswe ngokufanelekileyo ukuqinisekisa{4}}ukhuseleko lwexesha elide.

Isishwankathelo: UL3512 "yinkosi yokulinganisa" ephezulu{1}}yobushushu obuguquguqukayo beencingo

I-UL3512 ayinayo ubushushu obuphezulu obuphezulu beTeflon okanye ixabiso eliphantsi le-PVC, kodwa libetha ibhalansi phakathi kwe-200 yokumelana nobushushu, ukuguquguquka okuphezulu kunye nokugoba okuphezulu, ububanzi obubanzi beqondo lokushisa kunye nokumelana nokubanda, ukutshatyalaliswa komlilo kunye nobuhlobo bendalo, kunye nokulula ukusetyenzwa. Kubuninzi bezixhobo zobushushu obuphezulu -, amacandelo aguqukayo, amandla amatsha kunye neemeko zoshishino, sisisombululo esona sithathela ingqalelo ukusebenza, iindleko kunye nokwakhiwa.Ukuba ufuna iingcingo ezingagugiyo kumaqondo obushushu aphezulu, ungaqhawuki ngexesha lokugoba, kwaye ungaqini kumaqondo obushushu aphantsi, i-UL3512 iya kuba yinto enokuthenjwa kunye nexesha elide.
