1.What yog xhhw hlau?
Xhhw sawv rauHla-Txuas Polyethylene Muaj Kub Kub-resistant Dej-resistantCov. Qhov no thermoset rwb thaiv tsev cov khoom siv tshwj xeeb tiv thaiv kom sov, noo, tshuaj lom neeg, thiab puas. XHhW cov xov hlau tau nyob txog 90 degree (194 degree F) nyob rau hauv cov chaw qhuav thiab 75 degree (ua rau lawv muaj haum rau ob qho tib si sab nraud. Tus "Xhhw {{4 {}}}" variant ntsib tus qauv stricter strame-retardant thiab raug pom zoo rau kev siv hauv conduits, ductions, thiab qhia ncaj qha faus cov ntawv thov.
Cov Nta Tseem Ceeb Ntawm Xhhw Hlau:
Cov Kub Kub Kuj: Withstands kub txog li 90 degree.
Ya raws tsis kam: Qhov zoo rau cov chaw ntub lossis cov chaw ntub dej.
UV Kuj: Hla nrog polyethylene (xlpe) rwb thaiv tsev tsis kam tshav ntuj teeb meem.
Tshuaj Muaj Peev Xwm: Tsis kam roj, acids, thiab alkalis.
Yooj yooj: Muaj nyob rau hauv txhuas thiab tooj liab cov txiv neej rau ntau qhov kev siv.
2. Cov khoom lag luam ntawm XHHW hlau nyob rau hauv ib puag ncig sab nraum zoov
2.1 UV Yaus thiab Huab Cua Hluav Taws Xob
XHhw hlau's XLPE rwb thaiv tsev yog inherently UREHITY UREX-resistant, cia nws ua kom muaj kev ntseeg ncaj qha tsis muaj kev tawg lossis brittleness. Tsis zoo li PVC-insulated xov hlau (piv txwv li, thhn), xhhw tsis tas yuav tsum muaj kev cuam tshuam txog UV-thaiv cov conduits hauv kev teeb tsa sab nraum zoov. Txawm li cas los xij, hauv cov cheeb tsam nrog cov huab cua hnyav heev-xws li nag xob nag cua lossis nag xob nag cua-prone cov kev tiv thaiv-tshuab kev tiv thaiv (piv txwv li cov khoom siv nruj.
2.2 Dej thiab ya raws tsis kam
Tus "W" hauv XHHW sawv rau dej tsis kam. Lub rwb thaiv tsev tiv thaiv cov dej ingress, ua rau nws haum rau cov chaw ntub dej xws li cov conden nyob hauv av, thiab cov chaw muaj chaw muaj kev nyab xeeb. Piv txwv li,4 / 0 xhhw -2 xaim hlauFeem ntau siv nyob rau sab nraum zoov kev pabcuam entrances vim nws cov muaj zog noo noo tsis kam.
2.3 Kev Ua Si Kub Kub
XHHW tswj hwm nws txoj kev ncaj ncees thoob plaws ntau qhov ntau. Aluminium txawv li250mcm xhhw txhuasyog qhov zoo rau cov ntawv thov siab sab nraum zoov siab tam sim no, xws li pub cov tsiaj rau kev ua lag luam, qhov twg cua hloov pauv ntau yam.
2.4 Kev Siv Khoom Siv thiab Ua Txhuam Tuag Ua
Hauv ib puag ncig kev muaj ib puag ncig, XHHW hlau tiv thaiv raug cov roj, cov kuab tshuaj, thiab cov tshuaj corrosive.2AWG Xhhw -2}} txhuas hlauFeem ntau siv cov nroj tsuag tshuaj los yog dej khib nyiab chaw uas cov tshuaj tiv thaiv yog qhov tseem ceeb.
3.Thaum Xhhw hlau yuav tsum muaj kev tiv thaiv sab nraum zoov ntxiv?
Thaum XHHW cov hlau yog tsim rau sab nraum zoov detabab, qee cov xwm txheej yuav xav tau kev ceev faj:
Neeg kho tshuab puas tsuaj:
Hauv cov cheeb tsam muaj kev cuam tshuam, kev co kom muaj kev cuam tshuam, kev sib tw, lossis cuam tshuam rau cov tsiaj (piv txwv li cov kab tsuag), piv txwv, MC lossis AC). Piv txwv li,10AWG XHHW YIAS 1000VSiv nyob rau hauv cov chaw ua liaj ua teb yuav xav tau cov khoom siv hlau kom tiv thaiv cov nas kev puas tsuaj.
Qhia txog kev thov faus neeg:
Txawm hais tias xhhw -2 puas raug ntsuas rau kev tiv thaiv hauv zos zoo li cov av ua kom tiv thaiv av lossis ua pob zeb puas.2 / 0 xhhw hlau 600VFuried Unackgine nyob rau thaj chaw tsim kho feem ntau siv cov khoom siv rau ntxiv kev nyab xeeb.
Kev mob siab heev:
Nyob rau hauv cov ntug hiav txwv cheeb tsam nrog dej qab ntsev tsis sib xws, ntxiv, nylon-coated xhhw) tuaj yeem txuas ntxiv cov kav hlau.
