1.What yog xhhw hlau?
Xhhwsawv rauHla-Txuas Polyethylene Muaj Kub Kub-resistant Dej-resistantCov. It is a type of electrical wire designed for both dry and damp environments, with a temperature rating of up to 90 degree (194 degree F) in wet conditions and 90 degree –150 degree (194 degree F–302 degree F) in dry conditions, depending on the specific variant. Cov hlau muaj:
Tus coj nkauj: Feem ntau aluminium lossis tooj liab (stranded lossis tawv).
Kev rwb thaiv tsev: Hla nrog polyethylene (xlpe), paub txog nws lub durability thiab tiv taus kom sov, noo noo, thiab tshuaj lom neeg.
Lub tsho loj: Ib txheej txheej txheej tiv thaiv txheej, feem ntau ua los ntawm cov khoom noo-resistant cov ntaub ntawv xws li PVC.
Hom XHHW HlauFeem ntau siv hauv cov cwm kho hauv cov tshuab nkag, cov ntawv thov nkag nkag, thiab cov khoom noj. Txawm li cas los xij, nws cov kev haum rau kev faib hluav taws xob uas muaj ntau yam xws li cov kev ntsuas hluav taws xob, thiab ua raws cov qauv hluav taws xob zoo li cov xov xwm hluav taws xob hauv tebchaws (NEC).
2.xhw vs. Xhhw -2 xaim: sib txawv
ThaumHom XHHW Hlauyog pom tau dav,Hom Xhhw -2 xaim xaubMuaj cov yam ntxwv ua kom zoo:
2.1 Ntsuas Kub:
XHHW: Rated rau 90 degree nyob rau hauv cov chaw ntub thiab nce txog 150 degree hauv cov chaw qhuav.
Xhhw -2: rated rau 90 degree hauvob yamNtub dej ntub thiab qhuav, ua rau nws ntau ntxiv rau kev hloov chaw ib puag ncig.
2.2 Daim Ntawv Thov:
Xhhw -2 Puas tau pom zoo rau kev ua txhaum faus thiab siv hauv cov conduit ntawm lub hnub ci lossis roj.
Txheem XHHW yog txwv rau sab hauv tsev lossis kev tiv thaiv kev tiv thaiv.
2.3 Ua Raws:
Xhhw -2} Ua tau raws li Stricter ul 44 thiab UL 1277 tus qauv, kom tau raws li cov khoom siv hluav taws xob niaj hnub no.
Rau lub zog faib cov tshuab yuav tsum tau hloov kho kom haum rau cov mob hnyav,Hom Xhhw -2 xaim xaubfeem ntau yog qhov kev xaiv zoo dua.
3. Cov ntaub thaiv ntawm XHHW hlau hauv fais fab faib
XHHW xaim yog qhov kev nyiam rau lawv qhov sib npaug ntawm tus nqi, kav ntev, thiab ua tau zoo. Hauv qab no yog qhov tseem ceeb science uas lawv zoo:
3.1 ua lag luam thiab cov chaw muaj kev lag luam
Feeder Cij: Xhhw 1AWG(Cov ntsuas cua loj) yog qhov zoo rau cov neeg ua haujlwm siab tam sim no ntawm cov hloov pauv thiab xa cov khoom xa tawm.
Lub cev muaj zog loads: XLPE rwb thaiv tsev tiv thaiv kub kub txhawb los ntawm kev lag luam muaj peev xwm.
3.2 Kev Pabcuam Kev Ua Haujlwm
Xhhw 4AWGFeem ntau siv rau cov chaw nyob thiab cov kev lag luam kev lag luam me me vim nws qhov sib npaug ntawm ampacity thiab yooj.
3.3 Kev Tshaj Tawm
Thaum ntsia hauv conduit,Hom Xhhw -2 xaim xaubMuaj peev xwm tiv taus cov dej noo thiab cov av paug, ua rau nws cov kab hluav taws xob faus.
3.4 Kev Siv Zog Dua Tshiab
Hnub ci ua liaj ua teb thiab cua tshuab siv XHHW cov xov hlau rau kev sib txuas cov inverers rau cov inverers rau cov incls, ua tsaug rau lawv UV tsis kam (rau xhhw -2).
4.Cov Teshaujlwm sab xis: Xhhw 1awg Vs. Xhhw 4AWG
Hlau Koob Ntshav (AWG) txiav txim siab tam sim no-nqa lub peev xwm thiab voltage poob. Ntawm no yog li casXhhw 1AWGthiabXhhw 4AWGPiv:
| Chaw ua uas tsis tau haus | Xhhw 1AWG | Xhhw 4AWG |
|---|---|---|
| Qhov dav | ~ 7.35 hli | ~ 5.19 hli |
| Ampacity (Cu) | 130-150 A (75 DEGREE) | 70-85 A (75 DEGREE) |
| Kev Ntsuas Hluav Taws Xob | 600V-2KV | 600V |
| Raug siv cov ntaub ntawv | Cov Khoom Siv Hluav Taws Xob Loj, Hloov | Ceg Npe Ceg, Kev Pab Cuam |
Xhhw 1AWG: Qhov zoo tagnrho rau cov ntawv thov hnyav-ua haujlwm xws li cov nroj tsuag muaj cov nroj tsuag lossis cov ntaub ntawv.
Xhhw 4AWG: Haum rau kev thauj khoom hauv cov tsev lag luam lossis ntau tsev neeg nyob.
5.Installation kev coj ua zoo tshaj plaws
Txhawm rau kom ua tiav ntawm lub neej ntawm XHHW xaim hauv cov fais fab xa khoom siv:
Conduit compatibility: Siv PVC los yog hlau los tiv thaiv kev tawm tsam lub cev.
Zam kev dhau los: Ua raws li kev lom zem ampacity los tiv thaiv rwb thaiv rwb thaiv kev.
Ib puag ncig kev txiav txim siab:
Rau sab nraum zoov lossis cov chaw ntub, ua ntejHom Xhhw -2 xaim xaub.
Siv lub hnub ci-tiv taus cov khaub ncaws hauv UV-nthuav tawm.
Kev txiav hlo: Ua kom meej meej Lugs thiab cov txuas ntsuas rau XLPE rwb thaiv tsev.
6.Advantages ntawm XHHW hlau hauv kev faib khoom fais fab
Thaum Tshav Kub Kub Ua: XLPE rwb thaiv tsev withcal ntau dua kub tshaj li PVC.
Ya raws tsis kam: Tseem ceeb rau hauv av los yog damp ib puag ncig.
Nqi zog-ua hauj lwm: Ntau tus nqi pheej yig tshaj li cov xov hlau tshwj xeeb zoo li thhn / thwn -2.
Kev muaj peev xwm: Tsis kam ua kev tawg thiab kev puas tsuaj, txo cov nqi txij nkawm.
7.Tiabtations thiab lwm txoj kev xaiv
Thaum XHHW xov hlau muaj ntau yam, lawv yuav tsis haum txhua qhov xwm txheej:
High-voltage kis: Rau voltages saum 2kv, xav txog MV -105 lossis lwm yam nruab nrab-hluav taws xob cable.
Huab cua sov heev: Nyob rau hauv cov chaw ua si lossis chav nyob hauv tub yees, ntxhia-insulated (mi) cov xaim yog qhov zoo dua.
8.pliance thiab cov qauv
Xhhw xaim yuav tsum ua raws li:
Nec tsab xov xwm 310: Cwj pwm rau txoj kev dav dav dav dav.
UL 44: Cov qauv kev nyab xeeb rau cov thermoset-insulated.
Rohs / ncav cuag: Cov kev cai ib puag ncig.
Nco ntsoov txheeb xyuas cov ntawv pov thawj ua ntej ua tiav.
