Nyob rau hauv cov xwm txheej ntsuas (40 ° C ambient, ≤80% load tas mus li), lub thaiv tooj liab busbar terminal block uas tau teeb tsa zoo nrog PA66 vaj tse muaj lub neej tsim ntawm 20+ xyoo. Qhov tseeb tiag tiag uas txwv tsis pub lub neej siv yuav luag txhua lub sijhawm yog kev hloov pauv cua sov - qhov nthuav dav thiab kev sib cog lus ntawm lub tsheb npav tooj liab (CTE: 17 × 10⁻⁶ / K) tawm tsam lub tsev PA66 (CTE: 80 × 10⁻⁶ / K) maj mam ua rau cov ntsia hlau xoob dhau ntau txhiab lub voj voog. Kev rov ua kom muaj zog txhua xyoo thaum lub sijhawm saib xyuas raws sijhawm yuav ua rau lub neej ua haujlwm ntev dua.
Q: Kuv puas tuaj yeem tau txais kev teeb tsa busbar kev cai?
Yog. Ua ib lub chaw tsim khoom uas ua pwm hauv tsev, peb ib txwm tsim cov busbar terminal blocks uas muaj cov lej ncej tsis yog tus qauv, cov ntsuas tam sim no sib xyaw rau ntawm tib lub busbar, cov xim tshwj xeeb rau kev coding voltage, thiab kev cim / daim ntawv lo. Qhov tsawg kawg nkaus rau kev teeb tsa kev cai pib ntawm 1,000 units, nrog rau kev them nqi cuab yeej suav nrog rau hauv tus nqi ib chav. Hu rau peb pab neeg engineering ntawm sara@nbjguang.com nrog koj cov specifications.
Q: J-Guang cov thaiv davhlau ya nyob twg puas sib xws nrog cov khoom siv los ntawm lwm hom?
Peb cov DIN rail terminal blocks siv cov qauv kev lag luam TS-35 rail profile thiab tus qauv centerline spacing (feem ntau yog 6mm, 8mm, lossis 10mm nyob ntawm cov series). Cov brackets kawg, cov phaj faib, thiab cov cim kab feem ntau sib xws nrog cov hom loj (Weidmüller W-Series, Phoenix Contact UK-Series) vim tias cov qhov ntev no yog cov qauv kev lag luam tiag tiag - txawm hais tias peb ib txwm pom zoo kom xyuas qhov sib xws ntawm cov khoom siv nrog cov qauv ua ntej txiav txim siab rau cov xaj loj.
Vim li cas J-Guang thiaj li haum rau koj qhov kev xav tau ntawm DIN Rail Busbar Terminal Block
Peb tau tsim cov khoom siv terminal thiab cov khoom sib txuas txij li xyoo 2010 ntawm peb lub Hoobkas hauv Ningbo, Suav teb — 15 xyoos ntawm kev tsom mus rau cov khoom no. Peb tsis yog lub tuam txhab lag luam uas tau los ntawm cov chaw tsim khoom random; peb yog lub Hoobkas.
Peb cov kab khoom ntawm DIN rail busbar terminal block npog:
- Cov qhab nia tam sim no: 80A, 100A, 125A, 150A, 175A, thiab 200A
- Kev ntsuas hluav taws xob: 600V thiab 1000V AC (UL teev rau 600V; IEC ntsuas rau 1000V)
- Cov kab hlau: 1.5mm² txog 70mm² (AWG 16 txog 2/0)
- Kev teeb tsa ntawm tus ncej: 2-txoj kev mus rau 20-txoj kev, nrog rau kev teeb tsa tshwj xeeb muaj
- Cov hom kev sib txuas: Lub hau ntswj, lub caij nplooj ntoos hlav thawb rau hauv (≤16mm²), thiab lub pob ntsia hlau (≥35mm²)
- Cov ntaub ntawv vaj tse: PA66 GF30, UL94 V-0, kub ua haujlwm -40 ° C txog + 130 ° C
Txhua lub thaiv yog 100% kuaj hluav taws xob ua ntej xa khoom - tsis yog kuaj ua pawg, tsis yog kuaj los ntawm kev suav lej. Qhov no yog txoj cai uas peb tau siv rau xyoo 2015 tom qab ib qho kev xa rov qab uas taug qab mus rau qhov kev sib txuas ntawm busbar-rau-terminal uas kev sim ua pawg tsis tau ua tiav. Tus nqi yog kwv yees li $ 0.03 rau ib chav tsev hauv kev them nqi kuaj thiab cov neeg ua haujlwm; tus nqi yog xoom qhov ua tsis tiav hauv thaj chaw uas yog los ntawm qhov tsis zoo ntawm kev tsim khoom hauv xya xyoo dhau los.
