1. Ntawv pov thawj: Tus caj qaum ntawm Xhhw Hlau Kev Ntseeg
XHhw hlau lub ntiaj teb kev lees txais cov kav los ntawm nws cov xwm txheej ua kom cov qauv phom sij. Cov ntawv pov thawj no ua kom muaj kev nyab xeeb, kev ua tau zoo, thiab kev sib xyaw nrog cov hluav taws xob sib txawv.
1.1 Tau daim ntawv pov thawj (Underwriters Lub Chaw Haujlwm)
Feem ntau xhhw xov hlau, suav nrog4 / 0 xhhw -2 xaim hlauthiab3 / 0 xhhw tooj liab 600v, yog ul-npe, lees paub ua raws li UL 44 thiab UP 83 tus qauv. UL daim ntawv pov thawj lav:
Hluav taws kub tiv thaiv: XLPE rwb thaiv tsev nrog cov kub kub siab (txog li 90 degree hauv ntub dej / qhuav tej yam kev mob).
Kev Ntsuas Hluav Taws Xob: Muaj ntawv pov thawj rau 600V lossis 1000V daim ntawv thov, nyob ntawm seb loj loj thiab cov hom rwb thaiv tsev (piv txwv li,1 / 0 xhhw 1000hw 1000)3.
Khoom plig ncaj ncees: Tooj liab lossis txhuas tus sawv cev ua tiav kev ua haujlwm zoo thiab kev ua haujlwm ntawm cov tshuaj corrosion.
1.2 Lub Tebchaws Hluav Taws Xob Cov Hluav Taws Xob (NEC) Ua Raws
XHhw Hlau Ua Haujlwm nrog Nec tsab xov xwm 310, uas yog Gualsels rwb thaiv tsev, ntsuas kub thiab kev teeb tsa. Piv txwv li:
Ncaj Ncaj Kev Ua Neej Nkaus: Xhhw Ncaj NceesCov variants yog nec-raws rau hauv av siv yam tsis muaj conduit, ua tsaug rau noo noo-resistant xlpe rwb thaiv tsev.
Ampacity Cov Qauv: NEC cov ntxhuav txhais cov peev xwm tam sim no-nqa cov peev xwm rau qhov ntau zoo li1aj / 2awg xhhw, ua kom muaj kev nyab xeeb thauj khoom.
1.3 Cov ntawv pov thawj thoob ntiaj teb
Cov kws tsim khoom lag luam zoo li Shanghai Morn Khoom Siv Hluav Taws Xob Hluav Taws Xob Co., Ltd. Txuas ntxiv, XHHW cov xov hlau tuaj yeem ua raws li cov qauv hauv cheeb tsam xws li:
CSA (Canada): Rau tej yaam num ciam teb ciam teb.
CE (Tebchaws Europe): Kev ua raws li kev ua haujlwm hauv EU kev nyab xeeb.
IEC (International ElectroteCnical Commission): Rau ntiaj teb sib xyaw ua ke.
2. Kev ua tau zoo ntawm xhhw xaim
XHhw hlau tus tsim thiab cov khoom siv muaj pes tsawg ua rau nws zoo rau cov chaw xav tau. Hauv qab no, peb txheeb xyuas nws txoj kev ua tau zoo thoob plaws kev ntsuas.
2.1 Kev ruaj khov nyob rau hauv cov xwm txheej hnyav
Ya raws tsis kam: XLPE rwb thaiv tsev txwv tsis pub cov dej ingress, uaXhhw Ncaj NceesCes ncua kom tsim nyog rau hauv av.
Tshuaj thiab UV Kuj: Withstands raug cov roj, acids, thiab tshav ntuj, txo cov kev ua rau hauv kev lag luam lossis chaw sab nraum zoov.
Yooj yooj: Txawm gauges loj dua li4 / 0 xhhw -2 xaim hlauSaib xyuas kev lag luam, yooj yim installation hauv cov chaw nruj.
2.2 Kev Tiv Thaiv Kub Kub
Xhhw -2 cov variants, xws li3 / 0 xhhw tooj liab 600v, Ua haujlwm ntawm 90 degree nyob rau hauv cov chaw ntub thiab 150 degree nyob rau hauv qhuav ib puag ncig, outuptorated cov xov hlau.
2.3 voltage versatility
Kev thov 600v: Ntau yam nyob rau hauv lub tsev lag luam (piv txwv li,1aj / 2awg xhhwrau feeder circuits).
1000V muaj peev xwm: 1 / 0 xhhw 1000hw 1000Txhawb High-voltage muaj machinery thiab txuas txuas ntxiv dua.
2.4 tus nqi nyiaj tau zoo
Kev muaj peev xwm: Txo cov nqi hloov pauv vim yog rwb thaiv tsev uas muaj zog.
Zog Efficiency: Tsis kam cuam tshuam hauv tooj liab tus cwj pwm (piv txwv li,3 / 0 xhhw tooj liab 600v) feeb rau lub zog poob.
3. Cov Khoom Tseem Ceeb Khoom thiab Kev Siv
