THHN kab(Thermoplastic High Heat Resistance Nylon Coated Wire) yog cov xaim ua haujlwm siab siv dav hauv cov tsev, lub zog hluav taws xob, thiab cov xwm txheej kev lag luam, muaj npe tom qab nws qhov kub thiab txias tsis kam thiab cov khoom siv thermoplastic nylon rwb thaiv tsev. THHN cable tau dhau los ua qhov kev xaiv tseem ceeb hauv ntau yam kev siv hluav taws xob vim lawv txoj kev nyab xeeb, ua haujlwm ntev, thiab muaj peev xwm hloov mus rau ntau qhov chaw.
Core Composition thiab yam ntxwv ntawm THHN Hlau
Yuav kom nkag siab tias yog vim li cas THHN hlau yog hu ua high-temperature thermoplastic nylon coat xov hlau, nws yog thawj zaug uas yuav tsum to taub lawv cov ntsiab lus tseem ceeb thiab cov yam ntxwv ntawm kev ua tau zoo:
1.Conductor khoom
Copper conductor:Feem ntau ntawm THHN cable siv mos kos tooj liab raws li tus neeg xyuas pib, xws li: 2 THHN tooj liab hlau, 1 THHN tooj liab hlau, thiab 1/0 tooj liab THHN hlau, uas muaj cov conductivity zoo heev thiab corrosion kuj.
Aluminium conductor:Hauv qee qhov kev siv, lub teeb yuag thiab kev lag luam aluminium conductors xws li txhuas THHN hlau yog siv los txo cov nqi thiab qhov hnyav.
2. Cov khoom siv rwb thaiv tsev
PVC (polyvinyl chloride) txheej txheej rwb thaiv tsev: muab cov hluav taws xob rwb thaiv tsev yooj yim thiab kub ua haujlwm, ua kom muaj kev nyab xeeb ntawm cov xov hlau hauv qhov chaw qhuav txog li 90 ° C thiab qhov chaw ntub dej txog li 75 ° C.
Nylon txheej txheej: .txhim khu lub zog txhua yam, hnav tsis kam, thiab tshuaj tiv thaiv corrosion ntawm cov hlau, ua rau nws txhim khu kev qha hauv cov cheeb tsam nyuaj.
3.technical txuj
THHN hlau yuav tsum ua raws li UL 83 cov qauv thiab tseem ua tau raws li NEC (National Electrical Code) cov cai rau cov khoom siv hluav taws xob kub kub insulated.
Yog vim li casTHHN hlauLub npe hu ua "high-temperature thermoplastic nylon coat wire"?
1. Kub siab kam rau ua
THHN hlau muaj npe tom qab lawv muaj peev xwm tiv taus qhov kub thiab txias. Nov yog qee qhov ntsuas kev ua haujlwm tshwj xeeb:
Qhuav ib puag ncig kub txwv: 90 degree C (xws li 12 THHN hlau thiab 6 gauge THHN hlau).
Kev txwv qhov kub thiab txias: 75 degree C (xws li 8 AWG THHN cable thiab 4 AWG THHN hlau).
Qhov kev ua haujlwm kub kub no yog vim qhov thermal stability ntawm PVC sab hauv txheej thiab tiv thaiv cov nyhuv ntawm nylon txheej txheej, kom ntseeg tau tias cov xaim tuaj yeem ua haujlwm ruaj khov hauv qhov kub thiab txias lossis ib puag ncig nyuaj.
2. Thermoplastic rwb thaiv tsev txheej
Thermoplasticity "hais txog lub peev xwm ntawm THHN cov ntaub ntawv rwb thaiv tsev kom muag muag thiab txheej txheem thaum cua sov, thiab rov ua kom lawv cov ntaub ntawv ruaj khov tom qab txias. Cov yam ntxwv ntawm cov khoom no ua rau kom yooj yim ntawm cov hlau tsim, ua, thiab kev teeb tsa, thaum tseem ua kom nws yooj yim. hauv daim ntawv thov.
3. Nylon txheej txheej
Cov nylon txheej sheath muab cov hauv qab no tshwj xeeb zoo rau THHN hlau:
Hnav tsis kam: tshwj xeeb tshaj yog nyob rau hauv daim ntawv thov conduit, tsis tshua muaj kev sib txhuam ntawm nylon sheaths ua rau cov xov hlau yooj yim rau nruab.
Chemical corrosion kuj: Nylon sheaths zoo tiv thaiv qhov yaig ntawm cov roj thiab acidic tshuaj nyob rau hauv cov tshuaj thiab kev lag luam ib puag ncig.
Txhim khu lub zog tensile: Tiv thaiv cov xov hlau los ntawm kev puas tsuaj yooj yim nyob rau hauv kev ntxhov siab.
