THHN hlau, los yog Thermoplastic High Heat-resistant Nylon-coated hlau, yog dav pom nyob rau hauv cov hluav taws xob kev lag luam rau nws durability, versatility, thiab hluav taws kub. Feem ntau siv rau hauv kev lag luam thiab thaj chaw, THHN hlau yog ib qho tseem ceeb rau kev xaim hluav taws xob vim nws muaj peev xwm tiv taus ntau yam ib puag ncig. Kab lus no delves rau hauv cov khoom hluav taws-resistant ntawm THHN hlau thiab tshawb xyuas seb nws piv rau lwm yam khoom siv hluav taws xob.
Thermoplastic: Cov khoom yas uas softens thaum rhuab thiab hardens thaum txias.
Siab kub-resistant: Qhia tias nws muaj peev xwm tiv taus qhov kub thiab txias yam tsis muaj degradation.
Nylon-coated: Ib txheej tiv thaiv uas muab cov khoom siv dag zog ntxiv thiab ua haujlwm rau cov roj, roj av, thiab kev puas tsuaj.
Muaj nyob rau hauv ntau qhov ntsuas thiab hom, THHN hlau yog siv dav hauv qhov chaw qhuav thiab ntub dej. Nws cov qauv muaj xws li tooj liab lossis aluminium conductor, thermoplastic rwb thaiv tsev, thiab lub tsho nylon.
Hluav taws kub tsis kam ntawm THHN Hlau
Kev ntsuas kub
THHN hlau muaj qhov ntsuas kub zoo tshaj plaws uas ua rau nws tiv taus hluav taws. Nws yog rated rau:
90 degree (194 degree F) hauv qhov chaw qhuav
75 degree (167 degree F) hauv qhov chaw ntub dej
90 degree (194 degree F) rau THWN-2, hloov kho dua tshiab ntawm THHN, txawm tias ntub
Cov kev ntsuas no ua kom ntseeg tau tias THHN hlau tuaj yeem ua tau zoo nyob rau hauv cov xwm txheej kub kub, txo qhov kev pheej hmoo ntawm hluav taws kub vim overheating.
Nylon txheej thiab hluav taws kub tsis kam
Lub tsho nylon ntawm THHN xaim ua haujlwm ua ib txheej tiv thaiv ntxiv. Txawm hais tias tsis muaj hluav taws kub hnyiab, cov nylon txheej muab qhov tseem ceeb tiv thaiv tshav kub, txo kev puas tsuaj thaum lub sij hawm luv luv rau qhov kub thiab txias. Nws kuj tseem pab txo qhov kev pheej hmoo ntawm hluav taws xob hluav taws xob.
Flammability Standards
THHN hlau ua tau raws li cov qauv nruj nruj, xws li UL 83 Standard for Thermoplastic Insulated Wires thiab Cables. Kev ua raws li cov qauv no ua kom ntseeg tau tias cov xaim tau dhau los ua qhov kev sim nruj rau kev tiv thaiv hluav taws thiab kev nyab xeeb.
Cov ntawv thov nyob rau thaj chaw muaj hluav taws kub
THHN hlau muaj peev xwm tiv taus qhov kub thiab txias ua rau nws tsim nyog rau kev siv hauv ib puag ncig uas tuaj yeem raug tshav kub, xws li:
Cov nroj tsuag muaj
Hluav taws xob enclosures
Cov tsev nrog cov tshuab muaj zog
Thaum siv kom raug, THHN hlau yuav txo tau qhov tshwm sim ntawm hluav taws xob hluav taws xob los ntawm kev tswj nws txoj kev ncaj ncees nyob rau hauv kev kub ntxhov.
Kev sib piv nrog lwm hom hlau
Thaum THHN hlau yog qhov kev xaiv nrov rau nws qhov sib npaug ntawm tus nqi thiab kev ua haujlwm, nws yog ib qho tseem ceeb kom nkag siab tias nws piv rau lwm hom hlau hais txog hluav taws kub.
THHN vs XHHW
THHN hlau: Nylon-coated, haum rau qhov chaw qhuav thiab ntub dej.
XHHW kab: Hla-txuas polyethylene rwb thaiv tsev muaj kev tiv thaiv hluav taws zoo tshaj plaws thiab nyiam rau cov cheeb tsam uas muaj cua sov heev.
THHN vs MC Cable
THHN hlau: Tau nruab rau hauv cov kav dej rau kev tiv thaiv ntxiv.
MC kab: Feem ntau pre-assembled nrog lub tsho hlau, muab ib txheej ntxiv ntawm hluav taws kub.
THHN vs. Fire-rated Cables
Cov kab hluav taws xob hluav taws xob tau tsim tshwj xeeb los tiv thaiv hluav taws ncaj qha rau lub sijhawm ntev, ua rau lawv tsim nyog rau lub neej kev nyab xeeb dua li tus qauv THHN hlau.
Txhim khu kev tiv thaiv hluav taws nrog kev txhim kho kom raug
Kev txhim kho kom zoo yog qhov tseem ceeb heev rau kev ua kom cov hluav taws kub-tiv taus ntawm THHN hlau. Cov ntsiab lus tseem ceeb suav nrog:
Siv Conduit: Hlau conduits txhim khu kev tiv thaiv hluav taws los ntawm kev ua ib qho thaiv.
Tsis txhob overloading: Tshaj li cov xaim hluav taws xob tam sim no tuaj yeem ua rau overheating.
Tsis tu ncua: Kev tshuaj xyuas cov xov hlau tsis tu ncua tiv thaiv kev phom sij hluav taws.
