1.What yog xhhw hlau?
Xhhw sawv rauHla-Txuas Polyethylene Muaj Kub Kub-resistant Dej-resistantCov. Qhov no thermoset-insulated cable yog engineered kom muaj qhov kub thiab 75 degree nyob rau hauv qhuav cov xwm txheej) thaum muaj kuab lom, tshuaj lom neeg, thiab kev puas tsuaj rau lub cev. Nws tus ntoo khaub lig-txuas Polyethylene (XLPE) ua kom muaj kev xaiv ntev ntev, ua rau nws xaiv qhov kev xaiv ua lag luam, kev lag luam, thiab cov phiaj xwm chaw ua lag luam, thiab chaw nyob.
2.key nta ntawm xhhw hlau
2.1 kub kuj tsis kam:
XHhw lub rwb thaiv tsev XLPE tso cai rau nws kom ua haujlwm kom nyab xeeb, txo kev pheej hmoo ntawm rwb thaiv tsev rwb thaiv tsev lossis phom sij.
2.2 noo noo thiab tshuaj lom neeg Kuj:
Lub tsho tiv thaiv dej-resistant tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv hauv noo lossis hauv av sib sau. Nws tseem tiv cov roj, acids, thiab alkalis.
2.3 yooj thiab ruaj khov:
Txawm hais tias nws rwb thaiv tsev muaj zog, XHHW tseem yoog tau, yooj yim installation instuit nruab nrog cov lus qhuab qhia lossis cov chaw kaw.
2.4voltage ntsuam xyuas:
Feem ntau xhhw xov hlau, suav nrog3 / 0 xhhw tooj liab 600v, yog ntsuas rau 600V cov ntawv thov, zoo tagnrho rau kev faib khoom siv thiab cov khoom noj khoom haus.
3.is XHHW hlau tsim nyog rau kev faus faus?
Cov lus teb luv:Yog lawm, tab sis nrog cov xwm txheej.
Tus Qauv XHHW tau pom zoo rau kev sib twtsuas yog hais tias teev los ntawm cov khwthiab ua raws li lub teb chaws hluav taws xob code (nec). Txawm li cas los xij, tusXhhw -2Variant tau hais meej meej rau kev ua txhaum ncaj qha vim kev txhim kho rwb thaiv tsev. Cia peb tawg qhov no cia:
3.1 XHHW Vs. Xhhw -2}: Dab tsi yog qhov txawv?
Xhhw: Rated rau qhuav thiab nthwv qhov chaw. Yuav tsum conduit rau hauv av siv tshwj tsis yog lo rau kev faus neeg ncaj qha.
Xhhw -2: Nta thicker, tshav ntuj-tiv taus rwb thaiv tsev thiab ua tau raws li Stricter UL cov qauv (UL 44). Pom zoo rau kev ncaj ncaj uas tsis conduit tsis ntub lossis qhuav.
Rau cov phiaj xwm zoo li cov khoom noj hauv av lossis sab nraud teeb pom kev zoo,Xhhw -2} Txoj Kev Raug DabCables yog txoj kev mus daws.
