Thhw Hlau VS Thhak Hlau

Kuv {. Cov ntsiab lus tseem ceeb thiab cov qauv

Thhw hlau thiabThaub Hlauyog ob hom hlau hom txhais tau los ntawm National Electrical Code (NEC) ntawm Tebchaws Meskas {}} Lawv cov npe sawv cev txawv cov khoom sib txawv.

Nyob rau hauv dav dav, Thw Hlau muaj thermoplastic}}}}}}}}}}}}}} Cov txheej txheem dej tsis kam ua thiab tshuaj lom neeg ua haujlwm .

2. kev sib piv ntawm cov qauv kev sib xyaw
 

Txawm hais tias ob qho tib si siv PVC ua lub ntsiab txheej rwb thaiv tsev yog ib qho ntawm cov yuam sij los txiav txim cov cim kev xaiv thiab kev ua tau zoo {}}

Thhw Cable: Ib Leeg-Txheej PVC Rwb thaiv tsev pvc rwb thaiv tsev, tsis muaj kev tsim nyog sab nraud, tab sis nws tseem muaj kev siv zog hauv noo noo .

Thhn Cable: ib txheej ntawm nylon sheath yog coated nyob rau sab nraud ntawm cov tshuab hluav taws xob, acid thiab alkali tsis kam, thiab tensile zog.

Los ntawm cov txheej txheem kev pom, thhn xaim yog zoo dua nyob rau hauv cov tshuab puas tsuaj thiab corrosion tsis kam thiab corrosion tsis zoo xws li cable troughs lossis choj .

3. sib piv ntawm cov hluav taws xob thiab cua sov ua haujlwm
 

Los ntawm kev pom ntawm hluav taws xob kev ua tau zoo, thhw hlau thiab qhov sib txawv me ntsis nyob rau hauv qhov kub thiab kub nyob rau hauv huab cua dav dav hauv huab cua noo.

Nyob rau hauv luv luv, thhn cov xov hlau muaj qhov ruaj khov zoo dua nyob rau hauv cov dej kub siab thiab qhuav hauv cov ntaub ntub dej muaj ntau yam nyob rau sab nraum zoov ib puag ncig {}}

4. sib txawv hauv kev thov cov xwm txheej
 

1. Daim ntawv thov cov chaw ntawm ThhW Cable
Vim nws muaj zog lim dej thiab UV Kuj, THHW hlau feem ntau siv nyob rau hauv:

1.} Lub tsev lub tsev loj pob tw;

{{02. Kev Tso Tawm Sab Nraud thiab Kev Tso Tawm Hauv Av;

3.}} muaj kev tswj hwm cov tshuab;

{{04. fais fab faib rau hauv cov chaw puag ncig huab cua;

{5. dej kho cov nroj tsuag, chaw nres nkoj, cov nroj tsuag hluav taws xob thiab lwm qhov chaw uas muaj noo noo .

2. Daim ntawv thov ntawmThaub Hlau
Vim nws muaj zog kho tshuab zog muaj zog thiab tshuaj lom neeg ua hauj lwm, hlau thhn tau siv dav hauv:

Sab hauv kab ntawv faib;

{{01.} nraim nrog kev sib txuas ntawm cov khoom hluav taws xob;

2. Choj pw thiab cov ntaub yeeb nkab nkag mus siv;

{{03. HIGH-ROJ TSHEM TSHUAB nyob rau hauv cov tsev lag luam;

{{04.} Cov Khoom Siv Hluav Taws Xob hauv cov khoom siv qhuav .

5. UL Daim Ntawv Pov Thawj Faib thiab NEC Sckifications
Ob ThhW Cable thiab Thhn Hlau muaj ntawv pov thawj los ntawm UL (Underwriters Chaw Haujlwm) {}} Cov xov xwm kev teeb tsa thiab kev ua lag luam ua raws cai hauv North American lag luam.

Txawm li cas los xij, NEC cov lus qhia kom meej meej hais tias xaim peb tsuas yog siv cov xov tooj qhuav, lawv muaj peev xwm ua kom muaj kev tiv thaiv ntau ntawm 90℃thiab siv nyob rau hauv noo noo .

THHW hlau ib txwm muaj peev xwm siv tau rau hauv cov chaw noo noo, thiab lawv cov kev siv tau yog qhov ncaj qha rau .

{{0 {}} Yuav ua li cas los xaiv thhw cable lossis thhnable cable?
Thaum xaiv thhw hlau lossis thhn xaim, cov teeb meem hauv qab no yuav tsum tau txiav txim siab:

** Puas yog qhov chaw teeb tsa hluav taws xob noo? ** Yog tias yog li, thhw cable lossis composite clesles cim raws li thwn -2 cable.

** Yuav cov xov hlau tuaj rau hauv kev sib cuag roj lossis cov tshuaj pleev pob zeb? ** Yog tias yog li, thhn yog pom zoo .

** Puas yog lub zog yuav tsum tau rau kev tsim cov hlau xaim siab? ** PLAY CABLE nrog nylon txheej txheej yog ntau cov hnav-tiv taus-tiv taus thiab haum rau qhib hlau thiab dej xaim.

** Puas yog cov peev nyiaj tsis raug? ** THHW hlau muaj tus nqi me me kom zoo .

Hauv kev siv cov kev siv, sib xyawThhn / thwn -2 xaim xaubmuaj maj mam dhau los ua lub ntsiab lus vim lawv cov versatility thiab kev ua haujlwm zoo dua, thiab kub moist resistile and if if if} Yog tias cov peev nyiaj tau tso tawm, thiab lub sijhawm kub tau yooj yim thiab yav tom ntej nthuav tawm .
