Muindasitiri yewaya netambo, UL certification ndiyo mwero wegoridhe pamusika wekuNorth America uye nepamusoro-maapplications pasi rese. UyeXLPE, cross-yakabatanidzwa polyethylene, ndiyo yakanakisa kunhonga yekudzivirira zvinhu. Nekuda kwekuita kunoshamisa kubva muchinjika-nzira yekubatanidza, ndiyo nzira-yekugadzirisa magetsi epakati nepamusoro, pamwe ne{4}}tembiricha yepamusoro. XLPE inoumba 3D network mamolecular structure kuburikidza nechemical or physical cross-linking. Kuenzaniswa neyechinyakare PE zvinhu, inhanho hombe kumusoro mukupisa kupisa, simba remakanika uye magetsi ekudzivirira. Inogona kushanda patembiricha yakadzikama ye90~150 dhigirii , uye zvakare yakadzikira-utsi, halogen{13}isina, murazvo{14}}inorebesa uye ine eco{15}hushamwari. Izvi zvinoita kuti ive yakakwana kune zvakasiyana-siyana zvezvinodiwa mukuchengetedza simba, midziyo yemumaindasitiri, midziyo yemumba nezvimwe. Nhasi, tichatarisa pamafekitari edu 'ane mukurumbira UL waya modhi ine XLPE insulation -UL3817, UL3271, UL3321uyeUL3289- uye pwanya yavo yakakosha tekinoroji maficha uye mamiriro avanonakira.
Iko kukosha kwe XLPE insulation: Sei iri iyo sarudzo inosarudzika kune yakakwirira-yekupedzisira wiring?
Zvakanakira zveXLPE zvinobva pakiyi nzira ye "cross-linking". Nekutyora mutsara wemamorekuru cheni dze polyethylene uye kugadzira bhiriji zvisungo, inoshandura kubva ku "mutsara chimiro" kuenda kune "network chimiro", zvichikonzera kukwidziridzwa kwakazara mukuita: Chekutanga, kupikisa kupisa kunowedzera zvakanyanya. Tembiricha yenguva yakareba-yenguva yekushanda yePE yakajairika idhigirii 70 chete, ukuwo XLPE inokwanisa kuramba ichishanda padhigirii 90 - 150, ine-tembiricha yekuremerwa kwenguva pfupi inosvika 130 degrees, uye inogona kushingirira 250 madhigirii panguva pfupi; Chechipiri, kushanda kwemagetsi kwakanakisa, nekukwirira kwekudzivirira kwekudzivirira uye kuderera kwe dielectric kurasikirwa, iyo inokodzera mamiriro epakati uye epamusoro-voltage, uye iyo insulation layer inofanana uye iri nyore kupepeta, kufambisa kuvaka nekuisa; Chetatu, kuchinjika kwezvakatipoteredza kwakasimba, haashingirire kuoiri, asidhi nealkali, inoshingirira kusimba, uye isina halogen, inodzora murazvo uye haiburitse halogen ine muchetura{10}ine magasi panguva yekutsva, inozadzisa mitemo yeRoHS yezvakatipoteredza, nokudaro ichipa nguva yekuti vashandi vabude nekuchengetedzwa kwemidziyo. Uku kusanganiswa kwemaitiro kunoita kuti mawaya eXLPE akaiswa insulated UL ive sarudzo yakakosha pakutsiva tambo dzePVC uye kujairana ne-kumagumo ekupedzisira.
Tsanangudzo yakadzama yeMana Core Models: Performance Differentiation Yakachinjirwa kune Yakasiyana Mamiriro
UL3817: Iyo ine Simba yakakwira-voltage Adapter yeEnergy Storage Systems
UL3817 iXLPE-waya yakavharirwa yakanyatsogadzirirwa zviri pakati nepakati nepamusoro-voltage scenario, ine tembiricha yakayereswa ye125 degrees uye yakayerwa AC voltage ye3000V - inonyatsoenderana nekuomarara kwepamusoro-voltage uye yakakwirira{{6}inoda simba rekuchengetedza kana tambo yestradnde sisitimu. yakavharwa mhangura/mhangura isina chinhu, uye iyo insulation layer ndeye XLPE zvinhu. Inoita zvose zviri zviviri UL horizontal uye CSA FT2 vertical flammability tests, saka ine zvese zviri zviviri flame retadancy uye eco{10}ushamwari hwakavharidzirwa.Panyaya yechimiro, UL3817 ine rakafanana gobvu insulation layer, uye inowanikwa mumawaya geji kubva kuAWG 30 nzira yese kusvika pa 4/0 kubva pa 4/0. 19.00mm. Iwe unogona kutora iyo chaiyo mhando inochinjika zvichienderana nenzvimbo yezvinodiwa zvesimba rako rekuchengetedza midziyo. Mukushandiswa{20}kunyika,UL3817inonyanya kushandiswa pakubatanidza kudivi reDC remagetsi ekuchengetedza simba masisitimu - pakati pemamodule ebhatiri, masumbu ebhatiri, uye zvakare pakati pemasumbu ebhatiri nemabhokisi ekubatanidza pamwe nePCS. Nekushanda kwayo kwakanaka kwemagetsi uye yakaderera-halogen yehutsi{2}yemahara, inoita basa rakakosha mumagetsi-akakura ekuchengetera magetsi nemidziyo yekuchengetera simba rekugara. Iyo inodzivirira kudzivirira kuchembera kuchembera pasi pekushisa kwepamusoro uye yakakwirira voltage, uye inovimbisa kushanda kwakasimba kwesimba rose rekuchengetedza simba.
UL3271: Mutambi anochinjika kune akajairwa maindasitiri mamiriro
UL3271 iwaya yakabatikana zvikuru yeXLPE-ine voltage yakayereswa ye600V uye tembiricha inoshanda inosiyana kubva -40 dhigirii kusvika 125 dhigirii . Inoshanda zvakanaka kune zvese zvakamisikidzwa uye{10}}zvichimbidzo zvinofamba zvishoma, zvichiita kuti ive sarudzo yakakodzera yewaya mumidziyo yemuindasitiri. Kondakita wayo imhangura isina chinhu inosangana neIEC 60228 Kirasi 5 zviyero, uye muchinjika-yakabatana insulation layer inopa yakanakisa makemikari kuramba - inogona kumira kune acids, alkali uye mamwe marudzi egirizi. Inopasawo bvunzo dzekudzosa moto, saka inosangana nezvinodiwa zvekuchengetedza zvenzvimbo dzemaindasitiri. Kana zvasvika kune maapplication,UL3271inoshandiswa kune mota inotungamira, transformers, kugovera mapaneru uye wiring yemukati mumidziyo yemumba. Kunyangwe ari iwo mamodule ekudzora pamitsara yekugadzira otomatiki kana magetsi ekubatanidza mumidziyo yekutaurirana, kuita kwayo kwakadzikama kunodzikira pane isina kurongeka yekudzikira kunokonzerwa nekukanganisa. Pamusoro peiyo, iyi modhi inogona kugadziridzwa mumhando dzakasiyana-siyana dzemhando, izvo zvinoita kuti zvive nyore kusiyanisa zviratidzo zvakasiyana panguva ye wiring. Yayo shoma yekubhenda radius ingori 4 nguva dhayamita yetambo yekumisikidzwa yakagadziriswa, saka inokodzera kuradzika munzvimbo dzakasimba, dzakaoma.
UL3321: Specialized wiring Solution ye-tembiricha yepamusoro Midziyo yemumba
UL3321 ndiyo ine mwero wepamusoro-soro wekudzivirira kupisa kubva pamhando ina idzi - ine tembiricha yakayerwa inosvika 150 dhigirii uye yakayereswa voltage ye600V, uye yakanyatsogadzirirwa midziyo yemumba neyemumaindasitiri inoshanda munzvimbo dzinopisa-pamusoro. Iyo inoshandisa yakasungwa yakasungwa mhangura conductor ine XLPE insulation layer, ichizvikudza yakanakisa murazvo wemoto uye kunyungudika kuramba. Inogona kushanda zvakadzikama mumidziyo inopisa-yakakwirira yepamba yakaita sehovhoni, maheater nemaomesa, ichimira kusvika pakupisa kwakanyanya kunogadzirwa kana michina iyi ichishandiswa uye ichidzivirira kuti insulation isapfave kana kumonyoroka. Nehunyanzvi kutaura, UL3321 inopihwa UL758 uye UL1581 zviyero, uye inosangana neRoHS uye Low Voltage Directive zvinodiwa. Voltage yayo yetest inogona kusvika 2000V kusvika 3500V zvichienderana newaya gauji, saka kuvimbika kwayo kuri pamusoro-kwepamusoro. Kunze kwemidziyo yekumba-yakakwirira, modhi iyi inoshandiswawo kuita waya dzemukati mumidziyo yemumaindasitiri yakaita semahita emumaindasitiri nemahovhoni anopisa zvikuru. Kunyangwe pasi pemamiriro akapetwa kaviri ekushisa kwepamusoro uye high voltage, inogona kuramba yakagadzikana kushanda kwemagetsi uye simba remagetsi.
UL3289: Tembiricha yakakwira-inoenderana neminda yemidziyo nemidziyo yemumba
UL3289 inoburitsa kuita kwakafanana neUL3321, uye makiyi masimba ari mune ayo akatanhamara emuchina zvivakwa uye murazvo wemoto. Yayo XLPE insulation layer inobatwa zvakanyanya kuti ive yakanyanya kupfeka uye kusagadzikana - haigone kukuvara zviri nyore mumamiriro ezvinhu apo michina inodedera zvakanyanya kana kufamba kazhinji. Inosanganawo neIEC 60332-1-2 FT2 flame retardant standard, ine simba rekudzima zvivakwa uye hutsi hushoma hutsi kana hwaiswa pamoto. Kana zvasvika kumaapplication,UL3289inowanzo shandiswa kutungamira mota, wiring yemukati mumidziyo yemumba, uye kubatanidza magetsi mumichina yemaindasitiri. Yakanyanya kunakira nguva dzinoda kushivirira tembiricha yepamusoro uye kugadzikana kwakanaka kwemuchina, semichina mikuru yekuwachisa mumaindasitiri nekutakura michina inoshanda munzvimbo -inopisa. Zvichienzaniswa neUL3321, mhando mbiri idzi dzinopa-tembiricha yakafanana. Iwe unogona kusarudza pakati pavo zvine hunyoro zvichibva pane chaiyo mechanic zvinodiwa zvemidziyo yako uye bhajeti yako.

Tichitarisa patafura yeparameta yatakambopfuura, pakusarudza XLPE-mawaya akaiswa insulated UL, unofanira kutarisa pazvinhu zvitatu zvakakosha: tembiricha, voltage, uye mamiriro ekushandisa. Kana uchinge wakwirisa{2}}voltage magetsi ekuchengetedza magetsi, UL3817 ndiyo yaunosarudza. Kumadhigirii 150 kukwirisa-mhoteredzo yetembiricha yakakwira-midziyo inopisa yemumba nemahiitha emuindasitiri, ingave UL3321 kana UL3289 inoshanda zvakanaka. Kana iri nyaya yezvishandiso zvemaindasitiri, mamodules ekutaurirana, mota dzinotungamira, nemamwe mamiriro akafanana, UL3271 inoshamisira nekusiyana-siyana kwayo uye mutengo wayo{{12}unyanzvi. Panguva imwe chete, unofanira kuona kuti waya geji inoenderana nenzvimbo yekuisa. Nekumisikidzwa kwakamisikidzwa, teerera kune yakaderera beng radius.
