Tus qauv UL hlau, tseem hu ua Underwriters Laboratories hlau qauv, yog tus qauv tsim los ntawm Underwriters Laboratories hauv Tebchaws Meskas. Cov qauv no tsis yog tsuas yog siv dav hauv Tebchaws Meskas, tab sis kuj tau lees paub thiab tau txais kev pom zoo hauv ntau lub tebchaws thiab cheeb tsam. Tus qauv UL hlau yog paub txog nws cov kev xeem nruj thiab cov khoom pov thawj nplua nuj, suav nrog yuav luag txhua cov khoom siv hlau hauv kev lag luam hluav taws xob.
UL hlau tus qauv muab cov ncauj lus kom ntxaws specifications rau ntau yam kev ua tau zoo ntawm cov khoom siv hlau.
1. Kev ua haujlwm hluav taws xob ntawm cov xov hlau, suav nrog cov ntsuas hluav taws xob, lub peev xwm nqa tam sim no, thiab lwm yam.
2. Cov rwb thaiv tsev thiab kub tsis kam ntawm cov xov hlau yuav tsum muaj cov ntaub ntawv rwb thaiv tsev zoo thiab kev kub siab ua haujlwm kom ntseeg tau tias lawv txoj haujlwm ruaj khov mus ntev hauv cov khoom siv hluav taws xob.
3. Tus qauv UL xaim kuj tseem tsim cov kev cai nruj ntawm cov nplaim taws, huab cua tsis kam, lub zog siv hluav taws xob, thiab lwm yam ntawm cov xov hlau kom muaj kev nyab xeeb thiab kev ntseeg siab ntawm cov khoom nyob rau hauv ntau yam hnyav.
Qee cov qauv UL xaim yog raws li nram no:
UL1007 xaim 300V 80 degree, hluav taws xob xaim 32AWG-16AWG, ib leeg lossis liab qab tooj liab, tinned tooj liab hlau, txheem UL758. Kev sib txuas sab hauv ntawm cov khoom siv hluav taws xob thiab hluav taws xob;

UL1032 hlau 1000V90 degree hluav taws xob hlau 30AWG-4AWG. Ua los ntawm Micron los yog liab qab tooj liab, tinned tooj liab hlau, txheem UL758. Kev sib txuas sab hauv ntawm cov khoom siv hluav taws xob thiab hluav taws xob;
UL1061 hlau 300V 80 degree hluav taws xob hlau 30AWG -16AWG, ib leeg lossis liab qab tooj liab, tinned tooj liab hlau, txheem UL758. Kev sib txuas sab hauv ntawm cov khoom siv hluav taws xob thiab hluav taws xob;
UL1185 hlau 300V 80 degree ib leeg tub ntxhais shielded hlau, 30-4AWG ib leeg los yog liab qab tooj liab, tinned tooj liab hlau, siv rau kaw thiab playback systems, hluav taws xob circuits, thiab lwm yam;
UL1429 hlau 150V 80 degree cross-linked PVC xaim 30-16AWG, ib leeg lossis liab qab tooj liab, tin plated tooj liab hlau qauv UL758 sab hauv kev sib txuas hlau rau cov khoom siv hluav taws xob thiab hluav taws xob;
UL1430 hlau 300V 105 degree cross-linked PVC xaim 30-16AWG, ib leeg lossis liab qab tooj liab, tin plated tooj liab hlau qauv UL758 sab hauv kev sib txuas hlau rau cov khoom siv hluav taws xob thiab hluav taws xob;
UL1431 hlau 600V 105 cross-linked PVC xaim 30-16AWG, ib leeg lossis liab qab tooj liab, tin plated tooj liab hlau qauv UL758 sab hauv kev sib txuas hlau rau cov khoom siv hluav taws xob thiab hluav taws xob;
ULI704 hlau 300V 150 degree 32-10AWG nyiaj plated, tin plated, npib tsib xee plated mos tooj liab hlau, PTFE hlau, aviation metallurgy roj av twj thiab meters, transformer motor lead hlau.
Kev siv dav dav ntawm UL cov qauv xaim tau muaj kev cuam tshuam loj heev rau kev lag luam hluav taws xob.
Tus qauv UL xaim zoo ua kom zoo thiab muaj kev nyab xeeb ntawm kev xa hluav taws xob, muab cov neeg siv khoom siv hluav taws xob ruaj khov.
Hauv kev lag luam thoob ntiaj teb, UL ntawv pov thawj tau dhau los ua "passport" rau cov khoom siv hlau, ua kom yooj yim rau cov khoom nkag mus rau hauv kev lag luam thoob ntiaj teb.
Cov kev cai nruj ntawm UL cov qauv hlau kuj tau txhawb nqa kev tsim kho tshiab thiab kev tsim cov txheej txheem kev txhim kho hauv kev lag luam hluav taws xob, txhawb kev txhim kho kev lag luam.
Daim ntawv thov ntawm UL cov qauv hlau tsis yog tsuas yog siv rau cov tsev nyob thiab kev lag luam, tab sis kuj suav nrog ntau yam xws li kev lag luam, kev thauj mus los, thiab lub zog. Cov kev xav tau ntawm cov xov hlau sib txawv hauv ntau qhov chaw, yog li UL cov qauv hlau txuas ntxiv tau muab faib ua ntau pawg thiab qib ntawv pov thawj kom tau raws li qhov xav tau ntawm ntau yam kev lag luam.
