Phindu lalikulu la kutsekereza kwa XLPE: Chifukwa chiyani kuli chisankho chomwe chimakondedwa pamawaya apamwamba-?
Ubwino wa XLPE umachokera ku njira yayikulu ya "mtanda-kulumikiza". Pothyola maunyolo amtundu wa polyethylene ndikupanga zomangira za mlatho, zimasintha kuchokera ku "mizere yofananira" kupita ku "network structure", zomwe zimapangitsa kuti pakhale kukweza kokwanira: Choyamba, kukana kutentha kumakulitsidwa kwambiri. Kutentha kwa nthawi yaitali- kwa PE wamba kumangokhala madigiri 70 , pamene XLPE imatha kupirira kugwira ntchito mosalekeza pa madigiri 90 - 150 , ndi -kutentha kwanthawi kochepa komwe kumafika madigiri 130 , ndipo imatha kupirira madigiri 250 pa nthawi yaifupi; Kachiwiri, ntchito yamagetsi ndi yabwino kwambiri, yokhala ndi kukana kwakukulu kwa kutchinjiriza komanso kutayika kwa dielectric kochepa, komwe kuli koyenera kwa zochitika zapakatikati komanso zapamwamba, ndipo wosanjikiza wotsekera ndi yunifolomu komanso wosavuta kusenda, kuthandizira kumanga ndi kuyika; Chachitatu, kusinthasintha kwa chilengedwe ndi kolimba, kusagwirizana ndi mafuta, asidi ndi alkali, kusagwirizana ndi makina, komanso popanda halogen, sikumawotcha moto ndipo sikutulutsa halogen{10}yokhala ndi mpweya woyaka pamene kuyaka, ikukwaniritsa miyezo ya RoHS ya chilengedwe, motero imapereka nthawi yoti ogwira ntchito asamuke ndi kuteteza zipangizo.

Kufotokozera mwatsatanetsatane kwa Zitsanzo Zinayi Zazikulu: Kusiyana kwa Magwiridwe Antchito Kusinthidwa ku Zochitika Zosiyana
UL3817: Adapter Yamphamvu kwambiri-yamagetsi yamagetsi yosungirako magetsi
UL3817 ndi XLPE-waya wotsekeredwa m'njira yopangidwira mwapadera-zigawo zamagetsi, zoyezera kutentha kwa madigiri 125 ndi AC voliti ya 3000V - ndi zogwirizana kwambiri ndi zolimba kwambiri-zokhala ndi mphamvu yamagetsi ndi zapamwamba{{6}zimene zimafunikira pazigawo zolimba za kutentha kapena kutentha kwambiri. mkuwa / mkuwa wosabala, ndipo wosanjikiza ndi zinthu za XLPE. Imadutsa mayeso a UL horizontal ndi CSA FT2 vertical flammability, motero ili ndi kuchedwa kwa malawi-yaubwenzi. Mwa kamangidwe kake, UL3817 ili ndi zosanjikiza zokhuthala zofanana, ndipo imapezeka mu mawaya geji kuchokera ku AWG 30 mpaka 5/0 m'mimba mwake mpaka 5/0 mm. 19.00 mm. Mutha kusankha mtundu woyenera mosinthasintha malinga ndi zosowa za danga la zida zanu zosungira mphamvu. Mu{20}ntchito zenizeni padziko lapansi,UL3817amagwiritsidwa ntchito makamaka polumikizira mbali ya DC yamagetsi osungira mphamvu zamagetsi - pakati pa ma module a batri, magulu a batri, komanso pakati pa magulu a batri ndi mabokosi ophatikizira komanso ma PCS. Ndi mphamvu zake zamagetsi zamagetsi zotsika-zopanda utsi{2}zopanda utsi{2}zopanda utsi, zimathandiza kwambiri-pamalo akuluakulu osungira mphamvu zamagetsi ndi zida zosungiramo mphamvu zanyumba. Zimalepheretsa kukalamba kwa kutentha kwambiri ndi kutentha kwakukulu, ndikuonetsetsa kuti ntchito yokhazikika ya dongosolo lonse losungira mphamvu.
UL3271: Wosewerera wosunthika pamawonekedwe wamba amakampani
UL3271 ndi XLPE yosinthika kwambiri-waya wotchingidwa wokhala ndi magetsi ovoteledwa a 600V komanso kutentha kwake koyambira -40 digirii kufika ku 125 digirii . Imagwira ntchito bwino pakuyika makina osasunthika komanso{10}}mapulogalamu oyenda mothamanga kwambiri, zomwe zimapangitsa kuti ikhale yabwino kusankha mawaya pazida zamakampani. Kondakitala wake ndi mkuwa wopanda kanthu womwe umakwaniritsa miyezo ya IEC 60228 Class 5, ndipo wosanjikiza wolumikizana ndi mtanda umapereka kukana kwamankhwala abwino kwambiri - amatha kupirira ma acid, alkali ndi mitundu ina yamafuta. Imadutsanso mayeso a retardancy yamoto, motero imakwaniritsa zofunikira zachitetezo cha malo ogulitsa. Zikafika pamapulogalamu,UL3271amagwiritsidwa ntchito potsogolera ma motor, ma transfoma, mapanelo ogawa ndi mawaya amkati mu zida zapakhomo. Kaya ndi ma module owongolera pamizere yopangira makina kapena zolumikizira zamagetsi pazida zoyankhulirana, magwiridwe ake okhazikika amachepetsa nthawi yosakonzekera chifukwa cha zolakwika. Pamwamba pa izo, chitsanzo ichi chikhoza kusinthidwa mumitundu yosiyanasiyana yokhazikika, zomwe zimapangitsa kuti zikhale zosavuta kusiyanitsa zizindikiro zosiyana panthawi ya waya.

UL3321: Specialized wiring Solution pazida zapakhomo-zotentha kwambiri
UL3321 ndi yomwe ili ndi mphamvu zolimbana ndi kutentha kwambiri mwa mitundu inayiyi - ili ndi kutentha kwa madigiri 150 ndi mphamvu yamagetsi ya 600V, ndipo idapangidwira makamaka zida zapakhomo ndi zamakampani zomwe zimagwira ntchito-zotentha kwambiri. Imagwiritsa ntchito ma conductor amkuwa okhala ndi chitsulo cholumikizira cha XLPE, chodzitamandira chifukwa cha kuchepa kwamoto komanso kukana kusungunuka. Imatha kuyenda mokhazikika mu -zida zapanyumba zotentha kwambiri monga mauvuni, mahita ndi zowumitsira, kupirira kutentha kosalekeza komwe kumapangidwa pamene zipangizozi zikugwiritsidwa ntchito komanso kulepheretsa kuti zotenthetsera zisafewe kapena kupindika. Kunena mwaukadaulo, UL3321 ndi yovomerezeka ku UL758 ndi UL1581 miyezo, ndipo ikukwaniritsa zofunikira za RoHS ndi Low Voltage Directive. Voltage yake yoyeserera imatha kufika 2000V mpaka 3500V kutengera mtundu wa mawaya, motero kudalirika kwake ndikwapamwamba-kwapamwamba. Kupatula{16}}zida zamagetsi zapanyumba zotentha kwambiri, cholozerachi chimagwiritsidwanso ntchito ngati mawaya amkati m'zida zamafakitale monga ma heaters a m'mafakitale ndi{17}}mavuni otentha kwambiri. Ngakhale pansi pa mikhalidwe iwiri yovuta ya kutentha kwambiri ndi voteji yapamwamba, imatha kukhalabe yokhazikika yamagetsi ndi mphamvu zamakina.
UL3289: Kutentha kwambiri-kumagwirizana ndi makina ndi zida zapanyumba
UL3289 imapereka magwiridwe antchito ofanana ndi UL3321, ndipo mphamvu zake zazikulu zili pamakina ake apamwamba komanso kuchedwa kwamoto. Chipinda chake chotchingira cha XLPE chimayikidwa mwapadera kuti chitha kuvala kwambiri komanso chosagwira ntchito - sichiwonongeka mosavuta m'malo omwe zida zimanjenjemera kwambiri kapena zimayenda pafupipafupi. Zimakwaniritsanso muyezo wa IEC 60332-1-2 FT2 wodzimitsa moto, wokhala ndi mphamvu zozimitsa zokha komanso utsi wochepa kwambiri ukayaka moto. Pankhani ya mapulogalamu,UL3289amagwiritsidwa ntchito kwambiri popangira ma motor lead, mawaya amkati m'zida zam'nyumba, ndi kulumikizana kwamagetsi pamakina aku mafakitale.
