Thhn Thwn -2 14 pa leи} Tag nrho cov paed cov khoom siv lossis tawv

A: Yog, Koj xaim hlau tuaj yeem siv rau hauv cov chaw ntub. Thwn sawv rau "Thermoplastic cua sov thiab dej-resistant nylon-coated," thiab "W" hauv W "hauv W" hauv cov xaim yog tsim nyog rau ib puag ncig ntub dej. Hom xaim no yog tsim los tiv thaiv kev rau noo noo thiab tuaj yeem tiv thaiv kev nyab xeeb hauv thaj chaw uas nws tuaj yeem nkag mus rau sab nraum zoov cov ntawv thov, thiab lwm qhov chaw noo, thiab lwm qhov chaw noo, thiab lwm qhov chaw ntub dej lossis cov chaw ntub dej.

A: Thwn -2 Thiab xhhw -2 Yog ob hom hluav taws xob feem ntau siv hauv lawv cov ntaub ntawv rwb rwb, thiab cov ntawv thov raug.

1) Rwb thaiv tsev ntaub

Thwn -2: Cov rwb thaiv tsev yog tsim los ntawm cov khoom thermoplastic, feem ntau PVC (nrog rau cov nylon txheej rau kev tiv thaiv ntxiv. Qhov "th" sawv rau thermoplastic, "W" qhia tau cov khoom haum rau cov chaw ntub, thiab "n" qhia tias cov nylon txheej.

Xhhw -2: Cov rwb thaiv tsev yog ua los ntawm cross-txuas polyethylene (xlpe). "X" sawv ntsug hla, "HH" qhia tias muaj kev phom sij ntawm cov chaw ntub dej, thiab "2" yog hais txog qhov hloov kho tshiab nrog kev ntsuas kub siab dua.

2) ntsuas kub

Thwn -2: thwn {{1} Khij hlau muaj qhov ntsuas kub ntawm 90 degree (194 degree F) nyob rau hauv ob qho chaw ntub thiab qhuav. Qhov "{{{-2" qhia qhia cov hlau sib ntsib tus qauv ntsuas kub siab dua.

Xhhw -2}: xhhw {{1} Khi Khwv Kuj muaj qhov ntsuas kub ntawm 90 degree (194 degree F) nyob rau hauv ob qho chaw ntub thiab qhuav. Zoo li thwn -2, cov "-2" qhia nws ua tau raws li cov qauv kub siab dua.

3) durability thiab hloov tau yooj yim

Thwn -2}: recopoplastic rulationation ntawm thwn} Khij xaim hluav taws xob, thiab tshuaj lom neeg kom hla polyethylene. Nws tseem tsawg dua yooj yim dua li xhhw -2.

Xhhw -2}: Tus ntoo khaub ncaws sib txuas nrog polyethylene rwb thaiv tsev ntawm XHHW {} Khib hlau ntau dua, muab cov tshuaj puas zoo, thiab noo noo. Nws tseem yuav yooj yim dua, ua rau nws yooj yim dua ua haujlwm nrog thaum lub sijhawm teeb tsa.

4) Cov ntawv thov

Thwn -2: feem ntau siv nyob rau hauv cov conduit system, ob qho tib si hauv tsev thiab sab nraud, thiab kev lag luam, cov xwm txheej ntub dej uas ntub dej.

Xhhw -2: feem ntau nyiam nyob rau hauv cov chaw muaj kev lag luam lossis chaw hnyav uas yuav tsum muaj tshuaj lom neeg. Nws tseem siv nyob rau hauv cov conduit system tab sis yog nyiam tshwj xeeb rau ntev khiav lossis qhov twg cov hlau yuav raug rau kev ntxhov siab.

5) nqi

Thwn -2}: feem ntau tsawg dua kim vim yog cov khoom siv hluav taws xob rypigic rab.

Xhhw -2: Feem ntau kim vim qhov siab dua thiab muaj peev xwm loj dua thiab muaj cov rwb thaiv tsev polyethylene rwb thaiv tsev.

A: Thhak xaim feem ntau tsis pom zoo rau kev siv sab nraum zoov lossis hauv qhov chaw ntub vim nws cov khoom rwb thaiv tsev. Thhak xaim tuaj yeem siv rau hauv cov conduit nruab rau sab hauv tsev, nws tsis yog qhov zoo tagnrho rau kev cuam tshuam sab nraum zoov vim tias nws tsis yog tsim los tiv thaiv cov dej noo, hnub ci, thiab sib txawv ntawm qhov kub. Ntev ntev li kev mob sab nraum zoov yuav ua rau tsis zoo ntawm lub rwb thaiv tsev.
