1, Naming cov cai thiab kev tshawb xyuas cov ntsiab lus yooj yim
Ua ntej kev soj ntsuam peb hom xov hlau, peb xub xav kom nkag siab txog lawv lub keeb kwm.Thau Hlau, Thhn Wire, thiabKoj Puas Yog Tus Hlauyog txhua hom thermoplastic insulated xov tooj tau txhais los ntawm National Electrical Code (NEC) hauv Tebchaws Meskas, nrog txhua daim ntawv sawv cev cov yam ntxwv ua tau zoo:
| Hlau Hom | Lub ntsiab lus piav qhia |
| T | Thermoplastic (Thermoplastic khoom) |
| H | Thaum Tshav Kub Kub Ua: 90 Qib |
| Hh | High Thaum tshav kub kub kuj: 90 degree lossis siab dua |
| W | Ntub Dej (Haum rau cov chaw vaum) |
| N | Nylon (Nylon txheej tiv thaiv txheej txheem) |
Peb tuaj yeem xaus tias:
Thw Hlau:Thermoplastic + Thaum tshav kub kub-resistant (75 degree) + Haum rau cov av noo;
Thahn xaim:Thermoplastic + siab kub ua hauj (90 degree) + qhuav ib puag ncig + Nylon tiv thaiv txheej;
Tshav xaim xaim:Thermoplastic + siab kub resistance + noo noo txheej + Nylon tiv thaiv txheej txheem (zoo ib yam li cov khoom siv ntawm Thhais);
2, qhov sib txawv hauv cov hlau qauv thiab cov khoom siv
1. Cov khoom siv saib xyuas
Peb hom feem ntau siv cov tooj tooj liab feem ntau yog siv cov tooj liab tooj, tab sis cov txhuas xaiv kuj xaiv tau, tab sis tooj liab tus neeg xyuas khoom muaj ntau dua. Nws cov qauv tau muab faib ua ob daim ntawv: khoom thiab tso tseg. Stranded tooj liab cov neeg ua si yog softer thiab yooj yim los txua.
2. Rwb thaiv txheej txheej
Thw hlau yog insulated nrog PVC (polyvinyl chloride);
Thahn thiab Twn Cables tau them nrog txheej txheej ntawm nylon sheath nyob rau sab saum toj ntawm pvc kom txhim kho kev coj tawm thiab tshuaj lom neeg kuj.
3. Kev Tiv Thaiv Txheej Kho Txheej Txheem
Nylon sheat yog ib qho tseem ceeb ntawm Think / Thwn, uas tsis tsuas yog tiv thaiv cov khoom yaig los ntawm cov roj av txheej, corrosive gases, thiab lwm yam.
3, piv cov kev tsom xam ntawm kev ua haujlwm tsis
Hauv qab no yog kev sib piv ntawm cov qauv tseem ceeb ntawm peb hom xov hlau:
| Yam | Thau Hlau | Thaub Hlau | Koj Puas Yog Tus Hlau |
| Cov Khoom Siv Ua | Tooj liab los yog txhuas | Tooj liab los yog txhuas | Tooj liab los yog txhuas |
| Rwb thaiv tsev ntaub | Pvc | PVC + Nylon Tiv Thaiv Txheej | PVC + Nylon Tiv Thaiv Txheej |
| Thaum tshav kub kub-resistant kub | 75 degree (qhuav / ntub) | 90 degree (qhuav) | 90 degree (qhuav / ntub) |
| Nws puas tuaj yeem siv rau hauv cov huab cua noo | Tau | Tsis muaj | Tau |
| Nylon sheath | Tsis muaj | Tau | Tau |
| Ib puag ncig kev teeb tsa | Pipeline / Cable Tais / Raug Nthuav Tawm | Mas siv rau hauv cov chaw qhuav | Ob qho tib si qhuav thiab noo ib puag ncig tau txais tau |
| Cov Qauv Ntawv Pov Thawj | UL83 | UL83 | UL83 |
4, sib txawv ntawm kev siv cov xwm txheej thiab cov ntawv thov
1. Thau Hlau
Haum rau thaj chaw nyob thiab cov tsev lag luam 'fais fab rooj siv hluav taws xob, siv feem ntau siv rau kev tso cov raj xa nkoj lossis cov tais cab. Vim nws tsis muaj cov txheej nylon tiv thaiv, nws tsis pom zoo kom siv nws rau hauv ib puag ncig uas muaj kev pheej hmoo los yog tshuaj lom neeg cov phom sij.
2. Thhn Cable
Nws yog tsuas yog siv nyob rau hauv qhuav ib puag ncig xws li muaj vaj tse, kev tswj lub cev muaj zog, thiab xaim hluav taws xob conduit. Nws cov txiaj ntsig dag hauv qhov kub tiv taus thiab cov hnav zoo, ua rau nws tsim nyog rau kev pw ib puag ncig nrog cov chaw sib xyaw.
3. Thon cable
Ua ke cov cua sov ua kom sov ntawm thhn nrog kev yoog taus rau cov khoom siv cable thiab sab nraum zoov, khoom siv hluav taws xob, thiab lwm thaj chaw.
5, sib txawv ntawm cov kev cai thiab cov qauv
Lub Tebchaws Hluav Taws Xob (NEC) hauv Tebchaws Meskas muaj qhov kev txwv ntshiab ntawm kev siv peb hom xov hlau no. Piv txwv li:
Thole Cable yuav tsum tau ua haujlwm ntawm 75 degree lossis hauv qab thiab haum rau cov chaw noo noo;
Thhn Cable tuaj yeem siv rau hauv ib puag ncig qhuav ntawm 90 degree thiab tsis tuaj yeem siv rau hauv cov chaw noo noo;
Thwn Cable yog tseem haum rau 90 degree, tab sis tuaj yeem siv rau ob qho chaw qhuav thiab noo ib puag ncig ib txhij.
Nws yuav tsum raug sau tseg tias ntau thhn / Thbn cables ntawm kev ua lag luam yog feem ntau "{{{{}" dua li ob Cable muaj ob qho kev ua tau zoo thiab tuaj yeem siv raws li xav tau.
6, kev sib piv ntawm kev tsim kho thiab txij nkawm
Kev Tsim Kho Kev Siv Ua Haujlwm Yooj Yim:
Vim nws cov nylon tiv thaiv txheej, thaib / thwn Cable muaj cov kev ua tau zoo dua thaum mus dhau cov kav dej, txoSiv kev tsis kam;
Qhov kev sib txhuam coefficient ntawm thw xov hlau yog qhov tseem ceeb, xav tau ntau cov roj nplua nyeem thaum xov paj los ntawm cov kav dej.
Dabtsi yog khoov Radius:
Thhn thiab thwn muaj kev yooj yim dua li thw thiab yog qhov tsim nyog rau kev xaim hluav taws xob hauv qhov chaw nqaim;
Thw cov xov hlau yog qhov nyuaj rau qhov ua kom tawv me me hauv qhov chaw qis, kev tsim kho ntau dua.
Txij Nkawm Nyiaj Txiag:
Cov txheej nylon tuaj yeem txhim kho txhim kho kev xeb thiab kev laus tsis kam ntawm thhn / thwn, nrog nruab lub neej nruab nrab ntawm 30 xyoo;
Qhov kev pabcuam lub neej ntawm thw hlau nyob ntawm lawv qhov kev ua haujlwm, feem ntau nyob ib puag ncig 20 xyoo.
7, cov lus qhia dav dav thiab cov lus qhia xaiv
Txog kev yooj yim ntawm cov engineers thiab cov neeg ua haujlwm ua rau xaiv cov xov hlau, nws raug nquahu kom xa mus rau cov lus hauv qab no:
| Kev Siv Ib puag ncig | Pom zoo Hlau Hom Hlau |
| Nyob sab hauv tsev qhuav thiab tsis corrosive | Thhn Cable |
| Nyob sab hauv av noo lossis av ib puag ncig | Thon cable |
| Kev Siv Nyiaj Tsawg, Tsis Muaj Cov Feem Ntau | Thows |
| Kev Siv Hluav Taws Xob Sab Nraud / Kev Siv Tshuaj Sib Tw | Thon cable |
| Muaj Lub Cev Muaj Zog Tswj System | Thhn / thwn cable |
Tseem tsis paub tseeb tias xaim haum koj qhov project?Cov Chaw Tsim Tshuaj Ntau HlauMuaj ntau dua 30 xyoo ntawm kev tsim kev tsim, thiab nws cov khoom tau dhau UL, SAA, TUV, thiab lwm yam kev pom zoo thoob ntiaj teb. Yog tias koj muaj lus nug txog cov xaim lossis lwm cov lus nug, thov sab taw rau peb!
