Kusankhidwa kwa waya ndi chingwe popanga zipangizo zamakono zamakono ndi zamagetsi zimagwirizana mwachindunji ndi chitetezo cha mankhwala, kudalirika ndi kutsata malamulo. UL1672 ndi muyezo wochokera ku Underwriters Laboratories (UL) wa Appliance Wiring Material (AWM) ndipo ndi gawo lofunikira kwambiri pakugwiritsa ntchito mawaya amkati. Nkhaniyi ikupereka chidziwitso chatsatanetsatane cha waya wa UL1672 pogwiritsa ntchito magawo enieni aukadaulo ndi machitidwe amakampani, kuphatikiza magawo, kapangidwe kake, mapindu a magwiridwe antchito ndi mawonekedwe ogwiritsira ntchito, ndikuyerekeza ndi miyezo ina ya UL, kotero kuti mainjiniya, ogwira ntchito zogula zinthu ndi okonda zamagetsi amatha kumvetsetsa bwino mtundu wa waya womwe umagwiritsidwa ntchito kwambiri.
Zambiri za UL1672 Standard
Zofunikira zaukadaulo zikuphatikiza:
-
Mphamvu yamagetsi: 300V AC
-
Kutentha kovomerezeka: 105 digiri
-
Kondakitala: Mkuwa wolimba kapena wothira (njira yomatira ilipo)
-
Kusungunula: PVC (polyvinyl chloride)
-
Jaketi/Chophimba: PVC Yowonjezera kapena XLPVC (mtanda-yolumikizidwa ndi PVC)
-
Kuchedwa kwamoto: Kupambana mayeso a UL VW-1 ndi CSA FT1 ofukula
Poyerekeza ndi ma hook-waya okhazikika (monga UL1007), UL1672 imakhala ndi zomangika-zawiri (zotsekereza kuphatikiza ndi chophimba). Izi zimakulitsa kwambiri kukana kwa abrasion, mphamvu zamakina, komanso kukhazikika kwa chilengedwe, ndikupangitsa kuti ikhale yoyenera kwambiri pama waya amkati omwe amafunikira chitetezo chowonjezera.
Kapangidwe kazogulitsa ndi Katundu Wazinthu
Waya wamba wa UL1672 amakhala ndi zigawo izi:
1.Kondakitala: Wopangidwa-ndi mkuwa wonyezimira kwambiri, wopatsa mphamvu zamagetsi. Makondakitala otsekeka (mwachitsanzo, 7/0.193mm ya 24AWG) amapereka kusinthasintha kwapamwamba, kuwapangitsa kukhala oyenera kugwiritsa ntchito zomwe zimakhudza kupindika pafupipafupi. Mabaibulo opangidwa ndi zitini amapereka kuwonjezereka kwa okosijeni komanso kusungunuka.
2.Insulation: zinthu zofanana extruded PVC zimatsimikizira makulidwe osasinthasintha, kuthandizira kuvula kosavuta ndi kukonza ma terminal. PVC imapereka zinthu zabwino zotchinjiriza magetsi komanso mtengo-mwachangu.
3.Kuphimba Kwakunja: Chowonjezera chowonjezera cha PVC kapena XLPVC chimapereka chitetezo chamakina. Chophimbachi chimasiyanitsa UL1672 ndi mawaya amodzi-otsekedwa; makulidwe ake okhazikika amatsimikizira kukana abrasion ndi kukakamizidwa.
Zodziwika bwino zakuthupi:
1.Kukana kwachilengedwe: Kusamva madzi, mafuta, zidulo, zosungunulira, ndi kukula kwa fungal; oyenera malo mafakitale.
2.Kuchedwa kwamoto: Utsi wochepa komanso kawopsedwe kakang'ono; imakwaniritsa zofunikira zachitetezo chamoto.
3.Flexibility ndi processability: makulidwe yunifolomu facilitates yodziwikiratu waya amavula ndi soldering; imakana kusungunuka pokhudzana ndi chitsulo chosungunuka (makamaka mtundu wa XLPVC).
4.Color coding: Imathandizira mitundu yosiyanasiyana yamitundu (mwachitsanzo, yofiira, yakuda, yabuluu, yoyera) kuti izindikirike mosavuta.
Mwachitsanzo, pepala lodziwika bwino loperekedwa ndi fakitale yathu likuwonetsa kuti 18 AWG kondakitala wokhazikika amakhala ndi mainchesi akunja, kulemera ndi kukana zomwe zikugwirizana ndi miyezo, komanso kukana kwa conductor pa digiri ya 20 kusungidwa munjira yoyenera.
Kuwunika kwa Ubwino Wantchito
1. Chitetezo ndi Kutsata: Chitsimikizo cha UL chimasonyeza kuti chinthucho chayesedwa mwamphamvu mu labotale, kuphatikizapo kupirira kwa magetsi, kukalamba kwa kutentha, kuchedwa kwamoto, ndi kuyesa kupanikizika kwa makina. Msika waku North America, iyi imakhala ngati "pasipoti" yolowera m'magawo monga zida zapakhomo ndi zida zamankhwala. Mawaya omwe si-omwe si UL angakumane ndi kulephera kwa satifiketi kapena kuyika chiwopsezo pachitetezo.
2. Kutentha ndi Kukwanira kwa Voltage: Kutentha kwa madigiri 105 kumaposa mawaya ambiri a PVC (madigiri 80), kulola kuti ntchito ikhale yokhazikika pa kutentha kwakukulu kozungulira. Kuvotera kwa 300V ndikoyenera kumagawo ambiri otsika-magetsi amkati.
3. Kukhalitsa Kwamakina: Zomangamanga zapawiri-zosanjikiza zimathandizira kuti musakhumudwe, zomwe zimapangitsa kuti zikhale zoyenera kuyenda mozungulira m'mphepete kapena mkati mwa zida zonjenjemera. Poyerekeza ndi mawaya amodzi-wotsekeredwa, amachepetsa chiwopsezo cha kuwonongeka kwa zotsekereza.
4. Kugwirizana Kwachilengedwe ndi Kugwirizana: Opanga ambiri amapereka mitundu ya lead-yaulere, ya RoHS{2}}yogwirizana yomwe imathandiziranso certification ya CSA AWM, zomwe zimathandiza kuti ziphatikizidwe ziŵiri ziperekedwe kumsika waku North America.
5. Mtengo-Kugwira ntchito modalirika: Pamene mukupereka ntchito yodalirika, PVC{2}zopangidwa ndi PVC{2}zimakhala zotsika mtengo, zomwe zimapangitsa kuti zikhale zoyenera kupangidwa mochuluka.
Zochitika zazikulu zogwiritsira ntchito
UL1672 imagwiritsidwa ntchito kwambiri mu:
-
Mawaya amkati opangira zida zapakhomo: Zowongolera mpweya, uvuni wa microwave, zophikira mpunga, makabati opha tizilombo, ndi zida zina zapakhomo.
-
Zida zamagetsi: zowongolera, zida, zosinthira mphamvu, zotumphukira zamakompyuta, ndi zida zamagetsi zamagetsi.
-
Zida zamankhwala ndi zolondola: Kulumikizana kwamkati kwa zida zamankhwala zomwe zimafuna kudalirika kwambiri komanso kuchedwa kwamoto.
-
Ntchito zina: Maloboti, zowongolera zikepe, makina othandizira amagetsi apagalimoto (osakhala-zingwe zamagetsi), ndi zina zotero.
M'malo ogwiritsira ntchito, UL1672 imagwiritsidwa ntchito nthawi zambiri ngati hook yamkati-waya pazida zamakina, makabati owongolera, ndi zida. Kusinthasintha kwake ndi kukana kwa mankhwala kumatsimikizira ntchito yabwino m'malo oyika fakitale. Malinga ndi malangizo a UL, waya wamtundu uwu wa AWM umapangidwira mawaya a fakitale ngati cholumikizira chamkati cha zida.
Poyerekeza ndi miyezo ina ya UL
Kumvetsetsa komwe UL1672 ikukwanira kumathandiza pakusankha koyenera:
UL1007: Idavotera ma℃80 ndi 300V yokhala ndi-zotsekereza zosanjikiza imodzi; ndizochepa thupi ndipo zimagwiritsidwa ntchito popanga ma hook amkati-mawaya ammwamba. UL1672 imakhala ndi-masanjidwe apawiri omwe amapereka chitetezo chapamwamba.
UL1015: Kuvotera kwa 80-105 digiri ndi 600V; imagwira ma voltages okwera, ngakhale makulidwe ake amatha kusiyanasiyana, kupangitsa kuti ikhale yoyenera-magetsi owonjezera.
Mtengo wa UL1061: Zomwe zili-zovala zolimba za PVC; oyenera kujambula zida zenizeni.
UL1571: Features woonda kutchinjiriza; oyenera malo-mapulogalamu ochepera.
UL1672imapereka chiwongolero chabwino cha makulidwe, chitetezo, ndi mtengo wake, kupangitsa kuti ikhale yabwino-yoyenera kugwiritsa ntchito mapulogalamu omwe amafunikira chitetezo chowonjezera pomwe mphamvu yamagetsi sidutsa 300V.
Zochitika Zamakampani ndi Tsogolo
Kachitidwe ka zida zamagetsi ndi miniaturization, kuphatikiza kwakukulu ndi ntchito zanzeru, zomwe zimapangitsa kuti pakhale zofunikira zolimba kwambiri pamawaya amagetsi. UL1672 ikupitilizabe kusinthika ngati mulingo wokwaniritsa zofunikira zachilengedwe monga kutsata kwa RoHS, mawonekedwe aulere a halogen, ndi mawonekedwe a utsi wochepa. Kuphatikizika-zolumikizana ndi matekinoloje otsogola atsogola adzapititsa patsogolo magwiridwe antchito m'mibadwo yamtsogolo.
China ndiye maziko opangira mawaya amagetsi pagulu lapadziko lonse lapansi. Mafakitale ambiri ku China atumiza kunja kuchuluka kwa zinthu zomwe zimakwaniritsa miyezo ya UL1672, zomwe zimalimbikitsa kukula kwa zida zapanyumba ndi mafakitale apamagetsi.
Mapeto
Waya wa UL1672 ndiye chisankho chomwe mainjiniya ambiri amasankha chifukwa chachitetezo chake chodalirika, makina abwino kwambiri komanso kugwiritsa ntchito bwino. Uwu si waya "wapamwamba" kwambiri kunja uko, koma ndi imodzi mwazabwino komanso yolinganiza. Ngati mupanga mabwalo amagetsi apanyumba, kusunga zida zamafakitale, kapena zida zamagetsi zamagetsi, kudziwa UL1672 kudzakuthandizani kupanga zisankho zabwino.
Innovation ili ndi chitetezo ngati mzere wapansi. Waya wotsimikizika wa UL ndi njira yolimba yodzitchinjiriza pazogulitsa zanu komanso kwa omwe amagwiritsa ntchito malonda anu.
