Kev xaiv ntawm cov cables ncaj qha cuam tshuam rau kev nyab xeeb, kev ntseeg siab thiab kev pabcuam lub neej ntawm cov khoom siv hluav taws xob sab hauv, qis -voltage DC kis ntawm cov tsheb muaj tsheb thiab cov khoom siv tsis siv neeg. UL Style 2726, los yog yooj yim UL2726, yog ib tug multi-core Appliance Wiring Material (AWM) cable uas tau siv dav hauv qee daim ntawv thov vim nws qhov hluav taws xob me me, ntau -core qauv thiab yoog raws.
UL 2726 Basic Specifications thiab Structure
Raws li UL Style 2726 (public cov ntaub ntawv xws li Specialty Cable Corp.), nws yog ib tug multi-conductor cable nrog ib tug extruded uas tsis yog{3}} ib tug sheath:
-
Tus neeg xyuas pib: Khoom siv lossis cov khoom siv tooj liab tso tseg (feem ntau tin -plated lossis liab qab tooj liab stranded rau kev txhim kho yooj yim).
-
Rwb thaiv tsev: Cov khoom siv rwb thaiv tsev ua raws li cov chaw tsim khoom AWM program lossis raws li tau teev tseg (feem ntau PVC lossis cov khoom siv thermoplastic zoo sib xws).
-
Kev sib dhos: ob los yog ntau dua conductors, uas tuaj yeem sib tw ua khub lossis pab pawg thiab tom qab ntawd sib tw ua ke; lawv kuj tuaj yeem teem caij ua ke los ua ib lub tiaj tiaj, oval, lossis puag ncig cable. Lub strand suab tsis nruj me ntsis txhais. Kev xaiv txheej txheej txheej thiab muab tub lim yog muaj.
-
Tiv thaiv: xaiv tau
-
Overlay (yeem): A 6 mil lossis tuab PVC overlay tuaj yeem raug extruded mus rau tus neeg xyuas pib.
-
Sheath: PVC, thickness sib txawv nrog lub cable sab nraud txoj kab uas hla (piv txwv li, qhov nruab nrab qhov tsawg kawg nkaus 15 mils rau sab nraud diameters tsawg dua los yog sib npaug li 0.250 ntiv tes, yam tsawg kawg nkaus 12 mils ntawm txhua qhov chaw; loj txheej diameters yuav tsum tau thicknesses dua).
Hauv peb cov khoom siv tiag tiag, peb suav nrog cov kev xav tau ntxiv xws li VW-1 ntsug nplaim taws kuaj thiab RoHS ua raws, hais txog kev hloov pauv siab, ua haujlwm rau cov neeg kho tshuab kev ntxhov siab, roj tsis kam, thiab tshuaj lom neeg ua haujlwm, ua rau lawv tsim nyog rau cov cheeb tsam uas muaj kev vibration siab thiab poob siab. Qhov ntsuas hluav taws xob feem ntau yog 30V, thiab qhov ntsuas kub yog 60 degree, ua rau nws zoo tagnrho rau cov ntawv siv hluav taws xob tsawg DC.
UL2726 belongs rau AWM qeb thiab feem ntau yog siv rau hauv cov cuab yeej siv lossis hauv qhov chaw tiv thaiv, tsis yog hauv tsev thaiv lossis siab -voltage exposed applications.

Raws li pom nyob rau hauv lub rooj, UL2726 muaj qis voltage thiab ntsuas kub, tab sis nws cov qauv hloov tau ua rau nws haum rau ntau -core low-voltage scenarios;UL 1007yog tsim nyog rau ib leeg -core siab dua voltage sab hauv thaiv; UL 2464 npog ntau yam kev tswj cov teeb liab siv; thiabTIAB SA 20276feem ntau yog siv nyob rau hauv robotics lossis siab -kev siv mobile ceev. Kev xaiv yuav tsum tau ua raws li qhov tseeb voltage, qhov kub thiab txias, qhov xav tau ntawm kev txav mus los, thiab ib puag ncig kev teeb tsa.
Tej yam kev thov scenarios
Qhov tseem ceeb ntawm UL2726 yog nyob rau hauv nws qhov tsis tshua muaj hluav taws xob, ntau -core, yooj, thiab kev xaiv tiv thaiv, ua rau nws tsim nyog rau cov xwm txheej hauv qab no:
① Internal thaiv ntawm cov khoom siv hluav taws xob: rau cov teeb liab sab hauv lossis tsis tshua muaj hluav taws xob sib txuas hauv cov twj paj nruag, cov cuab yeej kuaj mob, tswj vaj huam sib luag, thiab lwm yam raws li nws txoj cai.
② DC low-voltage kis tau tus mob nyob rau hauv cov tsheb muaj (pob roj teeb nyob rau hauv hluav taws xob forklifts, stackers, pallet tsheb thiab lwm yam rau lub cev muaj zog controllers thiab tsav systems) Lawv feem ntau yog powered los ntawm 24V / 48V roj teeb systems thiab nrog siab tam sim no kos. Cov cables siv yuav tsum sawv ntsug ntau zaus, kev vibration thiab cuam tshuam.
③ Cov txheej txheem pabcuam hauv lub tshuab hluav taws xob sab hauv lub tshuab hluav taws xob muaj tsheb • Siv rau hauv cov roj teeb pib, lub tshuab hluav taws xob- roj teeb kev sib txuas, thiab cov hlua txuas hluav taws xob • Xav tau cov roj ua haujlwm thiab cov nplaim hluav taws xob.
④ Automated Guided Vehicles (AGVs) thiab Automatic Mobile Robots (AMRs) Txuas cov roj teeb rau tsav cov chav, sensors thiab tswj cov tshuab hauv cov tsev khaws khoom ntse thiab cov chav tsev semiconductor.
⑤ Lwm yam tsawg-voltage scenarios: Ib feem yog siv rau cov ntaub ntawv / lub teeb liab kis tau tus mob los yog luv luv- kev sib txuas ntawm cov khoom siv (kev tiv thaiv thiab impedance txuam yuav tsum tau lees paub).
Cov ntawv thov no sib sau ua ke hais txog kev siv tshuab ua haujlwm ntev, nplaim hluav taws xob, thiab muaj peev xwm xaim hauv qhov chaw kaw.
Cov ntaub ntawv siv tau
Case Study 1: Fais Forklift Battery-Txoj kev txuas lub cev muaj zog
Lub tuam txhab logistics thiab warehouses siv lub forklift hluav taws xob nrog lub peev xwm siab lithium-ion lossis lead-acid roj teeb txuas nrog lub tshuab hluav taws xob sivTIAB SA 2726multi-core low-voltage cables. Cov cables muaj ntau yam -stranded tooj liab conductors thiab PVC rwb thaiv tsev rau kev ntseeg tau zoo thaum pib thiab nres, tig thiab nruj aisles ntawm racks. Lawv kuj ua tau raws li cov qauv kev nyab xeeb, tau dhau qhov kev sim rau cov nplaim kab rov tav. Cov khoom siv tsis ua hauj lwm raug txo qis thiab kev saib xyuas lub voj voog tau ntev tom qab kev siv, uas tau ua pov thawj qhov zoo ntawm cov khoom siv nyob rau hauv ib puag ncig ntawm kev vibration siab thiab siab siab tam sim no.
Case Study 2: AGV/AMR Smart Factory Deployment
Hauv e- chaw lag luam warehouses thiab semiconductor manufacturing rhiav, UL2726 cables tau dav siv rau kev xaim los ntawm cov roj teeb los tsav thiab tswj modules hauv AGVs thiab AMRs. Cov cables 'siab yoog raws thiab ua haujlwm rau cov neeg kho tshuab kev ntxhov siab hloov mus rau cov xwm txheej zoo xws li kev sib txawv ntawm txoj kev thiab kev sib tsoo thaum muaj xwm txheej ceev, thaum lawv qis - pa taws, nplaim taws - cov khoom siv hluav taws xob txo qhov kev pheej hmoo ntawm hluav taws hauv chav huv. Ib lub chaw tsim khoom tau tshaj tawm tias tom qab tau txais kev cai- ua cov cables ua raws li UL2726, cov cuab yeej ua haujlwm ruaj khov txhim kho, ua tau raws li lub Hoobkas kev nyab xeeb thiab ib puag ncig yuav tsum tau ua.
Case Study 3: Internal Equipment and Diagnostic Instruments
Hauv cov khoom siv kho mob lossis cov khoom siv kuaj mob, UL2726 yog siv rau sab hauv multi-cim qis-voltage cabling. Kev xaiv cov ntawv thaiv kev tiv thaiv pab cuam cuam tshuam, thiab extruded sheaths pab txhawb kev teeb tsa. Muab piv rau ib qho -cov tub ntxhais cables, ntau- cov qauv kev sib xyaw ua ke txo cov cabling nyuaj thiab qhov xav tau ntawm qhov chaw.
Kev sib raug zoo ntawm cov yam ntxwv ntawmTIAB SA 2726mus rau qhov tsis tshua muaj hluav taws xob thiab kev hloov pauv siab qhia tau tias muaj kev nce ntxiv hauv kev ntseeg tau thiab kev nyab xeeb xws li cov xwm txheej. Nws raug nquahu kom ua lub peev xwm nqa tam sim no, khoov lub neej thiab kev ntsuas kev sib raug zoo thaum xaiv cov khoom, thiab xyuas cov khoom tshwj xeeb cov ntaub ntawv pov thawj UL.
Kev xaiv thiab siv ceev faj
1. nruj me ntsis raws li qhov voltage (30V chav kawm) thiab kub (60 degree) tsis pub tshaj specifications.
2. Saib xyuas tus neeg xyuas pib stranding thiab sheath thickness rau cov neeg kho tshuab lub neej.
3. Tsom ntsoov rau cov khoom uas muaj cov lej ua tiav UL thiab lwm yam ntawv pov thawj xws li RoHS/VW-1.
4. Thaum lub sij hawm installation, xyuam xim rau lub vojvoog dabtsi yog khoov kom tsis txhob muaj ntau tshaj stretching los yog compression.
5. Rau kev siv hluav taws xob ntau dua lossis sab nraum zoov, siv lwm hom UL (piv txwv li, lub tsev cables lossis traycables).
Thaum UL2726 tsis yog ib qho dav dav - lub hom phiaj siab - fais fab cable, nws ua lub luag haujlwm tseem ceeb hauv cov khoom siv hluav taws xob thiab kev lag luam qis -voltage DC daim ntawv thov. Los ntawm kev nkag siab txog nws cov kev qhia tshwj xeeb, qhov sib txawv ntawm cov khoom zoo sib xws, thiab tiag -cov ntawv thov hauv ntiaj teb, cov neeg siv tuaj yeem siv cov kev daws teeb meem zoo dua thiab muaj txiaj ntsig zoo.
