UL-izintambo ezisohlwini ziyindlela enhle yokusiza ukuqinisekisa ukuthi izintambo ezingaphakathi kwezinto zakho zikagesi neze-elekthronikhi ziphephile futhi zithembekile. Izintambo ze-XLPE ({2}}ezixhumene ne-polyethylene) ezigqunyiwe ze-UL zisetshenziswa kakhulu emshinini wokuzenzakalela wezimboni, ukulawula izinjini kanye nezisetshenziswa zamandla amasha ngenxa yamakhemikhali azo amangalisayo, ashisayo kanye nakagesi. Ezinye zezinhlobo ezivame kakhulu ze-UL XLPE yocingo olufakwe ngaphakathi yi-UL 3321, UL 3173, UL 3266, UL 3271 kanye ne-UL 3289 futhi sizoxoxa ngazo kulesi sihloko. Umqondo uwukusiza onjiniyela nabathengi ukuthi benze izinqumo ezingcono.
I-XLPE insulation material: Kungani isiphenduke into ekhethwa yimboni?
I-XLPE, noma-i-polyethylene ehlanganisiwe, iwumsebenzi amaketanga wamamolekyuli akha -uhlaka lwenethiwekhi enobukhulu obuthathu ngokusebenzisa amakhemikhali noma{2}}izinqubo ezixhumanisayo{2}}, ethuthukisa ngokuphawulekayo ukuzinza kwayo kokushisa, amandla emishini, kanye nezakhiwo zikagesi. Uma iqhathaniswa ne-PVC yendabuko, i-XLPE inezinzuzo ezibalulekile ezilandelayo:
· Ukumelana Nokushisa Okuphezulu: Izinga lokushisa eliqhubekayo lingafinyelela ku-125℃~150℃, lihlale lizinzile ngisho nangaphansi-lokulayishwa ngokweqile kwesikhathi esifushane ngaphandle kokuthambisa noma ukuwohloka.
· Izakhiwo zikagesi: Amandla e-dielectric aphezulu kanye nokumelana nevolumu ephezulu, afanele ukusetshenziswa kwamandla kagesi aphakathi nendawo naphezulu.
· Ukumelana Nendawo Ezungezile: Ukumelana nowoyela, izincibilikisi, nokuguga; isilinganiso se-flame retardant ngokuvamile siphumelela i-UL VW-1 noma ukuhlolwa kwe-flame retardant evundlile.
· Ukuvikelwa Kwemvelo Nokuphepha: Ukuthobelana nezindinganiso ze-RoHS kanye ne-REACH, intuthu ephansi ne-halogen ephansi (amanye amamodeli), kunciphisa ubungozi bomlilo.
Lezi zici zenza izintambo ze-XLPE zibe enye indlela eyongayo kunezintambo zerabha ye-silicone noma i-fiberglass insulated, ikakhulukazi ezilungele{0}}izinga lokushisa eliphezulu, isikhala{1}sezimo zezintambo zangaphakathi ezibambekile.
UL3321: Inkosi Yamazinga Okushisa Aphakeme ku-150 degree
Izinhlelo zokusebenza ezijwayelekile:
-
Izintambo-zezinga lokushisa eliphezulu ngaphakathi kwezinto zikagesi
-
Imishini yokukhanyisa, izifudumezi, iziguquli zefrikhwensi
-
Isikhungo sedatha amasistimu e-UPS kanye neziphakeli zamajeneretha
Imelana kakhulu nokusikwa noma ukuhuzuka futhi ihlala iguquguquka kakhulu ngisho nangemva kokusetshenziswa isikhathi eside ku-150 degree. Ingakwazi ukuthwala izintambo zamanje eziningi kunezintambo ezijwayelekile ze-PVC, ngakho-ke awudingi ukukhathazeka ngokukhetha igeji yocingo efanele. Lokhu konga isikhala nemali. Abakhiqizi abaningi bahlinzeka ngombala wangokwezifiso kanye nezinsizakalo zokumaka eziphrintiwe, okwenza kube lula ukunquma ukuthi ukufakwa kuphi. Isibonelo, umenzi omusha we-inverter wamandla wandise amandla okukhipha ukushisa kwemishini futhi washintsha izintambo ze-silicone ukuyaI-UL3321-izintambo eziqinisekisiwe, ezehlisa kakhulu izinga lokuhluleka.
I-UL3173: Inketho-esebenzayo yezindleko (125℃/600V)
I-UL3173 iwumkhiqizo olinganiselayo wemishini ejwayelekile yezimboni ekwazi ukumelana namazinga okushisa aphakathi nendawo ukuya phezulu. Ukucaciswa komqhubi okuguquguqukayo. I-XLPE insulation imelana kakhulu namakhemikhali namanzi. Le modeli inesitifiketi se-CSA futhi ilungele ukusetshenziswa ezindaweni ezimanzi noma ezomile.
Izici Eziyinhloko:
-
Izomnotho futhi ifanele{0}ukukhiqizwa kwevolumu ephezulu
-
Ukwehla kwelangabi okuhle kakhulu nokuzinza kukagesi
-
Kulula ukuhlubula kanye ne-solder, ukuthuthukisa ukusebenza kahle komhlangano
Izinhlelo zokusebenza: Imithombe yezimoto, izintambo zangaphakathi emakhabetheni okulawula, ukuxhunywa kwama-transformer,{0}}izingxenye zethempelesha eliphezulu ezintweni zikagesi zasendlini, njll. Abahlinzeki abaningi'I-UL3173uchungechunge futhi lusekela{0}}amakhondaktha anesibopho esindayo ukuze kube nokuguquguquka okuthuthukisiwe.
Kumaphrojekthi alawulwayo-ebhajethi, i-UL3173 ngokuvamile iyinketho yokuqala, ukuhlangabezana nesitifiketi sokuphepha se-UL kuyilapho kulawulwa izindleko ngempumelelo.
I-UL3266 ne-UL3271: Izinkanyezi Ezimbili ze-300V kanye ne-600V
I-UL3266 (125℃/300V) kanye ne-UL 3271 (125℃/600V) amalungu ahlukahlukene omndeni we-XLPE.
· I-UL3266: Inikeza isilinganiso se-voltage esimaphakathi, esilungele amasignali okulawula amandla kagesi aphansi-kanye nezinto ezisizayo zamandla. I-insulation yayo i-radiation{2}}i-XLPE exhumene, inikeza ukuguquguquka okuhle kakhulu. Ifanele okokusebenza kwezokwelapha, izinsimbi, kanye nogesi wezimoto.
·I-UL3271: Inikeza ukwesekwa kwamandla kagesi aphezulu, okuyenza ibe insika kumamotho kanye ne-automation yezimboni. Ukujiya kodonga okulungiselelwe kuthuthukisa ukumelana nokuhuzuka namandla aqinile.
Zombili zisebenzisa ama-conductor ethusi afakwe emanzini futhi zine-insulation efanayo; umehluko omkhulu ulele ku-voltage nokugxila kwesicelo. Amaphrojekthi amaningi asebenzisa amamodeli womabili ngasikhathi sinye.
I-UL3289: Inketho ye-premium ye-150 degree
I-UL3289 kanye ne-UL3321 yomibili ingeyezinga le-150 degree, kodwaI-UL3289inokufakwa kokucaciswa okubanzi. Ukufakwa kwayo kwe-XLPE kukhombisa izici ezinhle kakhulu zomshini emazingeni okushisa aphezulu, okuyenza ifanelekele-ikhebula elisindayo noma{2}}elide{2}}elikude.
Izinzuzo Eziyinhloko:
-
Amandla okuthwala aphezulu kanye nokumelana nokuguga
-
Isetshenziswa kakhulu kumandla amasha, ezokuthutha zikaloliwe, namathuluzi ezimboni asindayo
-
Ihambisana nezitifiketi eziningi zamazwe ngamazwe (UL + CSA)
Kumandla omoya noma amakhabethe e-inverter e-photovoltaic, i-UL3289 ingakwazi ukumelana nokuguquguquka okukhulu kwezinga lokushisa, iqinisekise{1}}ukusebenza kwesistimu ezinzile isikhathi eside.

Izincomo zokukhetha:
·Izinga Lezinga lokushisa Okumqoka: Khetha okuthi 3321/3289 ngezinga lokushisa elingaphezu kuka-125℃.
·Ukucatshangelwa kwamandla kagesi nesikhala: Khetha okuthi 3173/3271/3289 ukuze uthole amandla kagesi angaphezu kuka-600V noma izidingo zamanje eziphezulu.
·Ezinye Izinto: Cabangela ukuncipha kwelangabi (VW-1), izimfuneko zokuvikela, irediyasi egobayo, namadokhumenti esitifiketi. Ngaso sonke isikhathi hlola inombolo yedokhumenti Yesevisi Yokulandelela ye-UL ngesikhathi sokuthenga ukuze uqinisekise ukufana kwenqwaba.
·Amanothi okufaka: Nakuba i-XLPE imelana nokushisa{0}}, gwema ukugoba ngokweqile; sebenzisa amathuluzi ochwepheshe lapho ukhumula izintambo ukuze uvimbele ukulimala kokufakelwa.
Kumaphrojekthi wangempela, kunconywa ukwenza isampula yokuhlola ngokusekelwe endaweni yokusebenza kwezisetshenziswa futhi uxhumane nomhlinzeki wekhebula ochwepheshile ukuze uthole imininingwane yakamuva nokusekelwa kobuchwepheshe.
Amathrendi Azayo Ezintambo Ze-UL XLPE
Izimboni ezintsha, imithombo emisha yamandla iyathuthuka, isidingo sezintambo ezinhle siyanda. Izinto ze-XLPE ziyashintsha ukuze zifake intuthu ephansi, i-halogen{1}yamahhala, izilinganiso zokumelana nezinga lokushisa eliphezulu nezici ezihlakaniphile ezifana{2}}nezinzwa ezakhelwe ngaphakathi. Ngokuzayo, isitifiketi se-UL sizogxila kakhulu ekusebenzeni nasekusimameni kuwo wonke umjikelezo wokuphila.
Ukukhetha izintambo zekhwalithi ze-UL XLPE akuwona nje umthetho, kuwukutshalwa kwezimali okuhlakaniphile okuzokwenza okokusebenza kwakho kuphephe futhi kuhlale isikhathi eside.
