Cov haujlwm ntawm cov hlau hlau raceways yog dab tsi? Lawv txawv li cas ntawm cov cable trays?

Cov no yog cov kev paub tseem ceeb uas txhua tus yuav tsum nkag siab. Tib lub sijhawm, nws tseem ceeb heev uas yuav tsum piav qhia qhov txawv ntawm cov hlau hlau thiab cov tais cable kom nkag siab zoo dua txog ob yam khoom no.

Niaj hnub nim no, muaj coob tus neeg siv cov hlau hlau raceways thaum lub sijhawm kho dua tshiab, thiab lawv daim ntawv thov tau dav heev. Txawm li cas los xij, ntau tus neeg yuav tsis paub txog lawv cov yam ntxwv tshwj xeeb. Cov haujlwm tiag tiag ntawm cov hlau hlau raceways yog qee yam uas txhua tus neeg yuav tsum paub. Tsis tas li ntawd, nws yog ib qho tseem ceeb kom nkag siab txog qhov sib txawv ntawm cov hlau hlau raceways thiab cov tais cable kom nkag siab zoo dua txog cov yam ntxwv ntawm ob yam khoom no.

Cov Haujlwm Tseem Ceeb ntawm Cov Hlau Hlau Raceways

Cov hlau hlau sib tw yuav tsum ua raws li ntau yam qauv ntawv pov thawj thoob ntiaj teb, xws li UL (Daim ntawv pov thawj hluav taws xob hauv Tebchaws Meskas), CSA (Daim ntawv pov thawj qauv Canadian), CE (kev ua raws li cov khoom siv hluav taws xob qis hauv Tebchaws Europe), DVE (Daim ntawv pov thawj German rau kev tshuaj xyuas cov ntaub ntawv hluav taws xob thiab hluav taws xob), thiab ROHS (daim ntawv pov thawj tiv thaiv ib puag ncig thoob ntiaj teb).

Cov kev sib txuas ntawm cov hlau hlau feem ntau yog siv rau kev tso cov xov hlau, muab kev tiv thaiv thiab ua kom cov xov hlau huv si thiab zoo nkauj. Lawv khi cov xov hlau thiab pab tiv thaiv hluav taws lossis kev raug mob hluav taws xob los ntawm cov xov hlau tsis zoo.

Cov hlau hlau sib tw ua kom cov xov hlau lossis cov yeeb nkab roj hmab tsis txhob ntswj thiab hloov pauv ntawm cov hlua hlau thiab cov tais. Lawv muaj cov qauv tsim niaj hnub, cov qauv tsim nyog, muaj kev ywj pheej siab, thiab tiv taus kev hloov pauv. Lawv yooj yim rau nruab, siv tau yooj yim, thiab yooj yim rau kev rhuav tshem thiab rov sib dhos, nrog rau qhov tsawg kawg nkaus sagging. Lawv feem ntau siv rau hauv cov tshuab xws li cov cuab yeej tshuab rau cov xov hlau, cov kav roj, cov kav cua, cov kav dej, thiab cov kav cua, ua haujlwm ob qho tib si kev coj thiab kev tiv thaiv.

Cov hlau hlau raceways, tseem hu ua wiring ducts, distribution ducts, lossis trunking (txawv ntawm thaj chaw), yog cov khoom siv hluav taws xob siv los kho thiab kho cov cables xws li cov xov hluav taws xob thiab cov xov ntaub ntawv ntawm phab ntsa lossis qab nthab kom zoo nkauj thiab ruaj ntseg.

Qhov Sib Txawv Ntawm Cov Hlau Hlau Raceways thiab Cable Trays

Qhov Txawv ntawm Lub Tswv Yim: Cov tais cable feem ntau yog siv rau kev tso cov xov hluav taws xob thiab cov xov tswj, thaum cov hlau hlau raceways feem ntau yog siv rau kev tso cov xov hluav taws xob thiab cov xov sib txuas lus.

Qhov Loj thiab Qhov Txawv ntawm Cov Qauv: Cov tais cable feem ntau loj dua, tshwj xeeb tshaj yog hais txog qhov khoov vojvoog thiab qhov ntev, muab kev ruaj khov dua. Lawv feem ntau siv rau hauv cov plag tsev, ntau chav faib khoom, thiab lwm qhov chaw. Cov hlau hlau raceways me dua, nrog rau cov khoov feem ntau ntawm cov ces kaum sab xis thiab qhov ntev me dua.

Txoj Kev Teeb Tsa thiab Kev Kaw: Cov hlau hlau feem ntau yog cov qauv kaw nrog lub hau, feem ntau siv rau kev teeb tsa hlau thiab feem ntau pom muaj nyob rau hauv cov txee faib khoom thiab cov txee ntsuas. Cov tais cable, qee zaum, yog tsim tsis muaj lub hau thiab feem ntau yog siv rau kev tso cov cables loj.

Zuag qhia tag nrho, cov hlau hlau raceways tuaj yeem suav hais tias yog ib pawg me ntawm cov cable trays. Cov cable tray systems suav nrog cov brackets, accessories, supports, thiab dai Cheebtsam, nrog rau cov qauv tseem ceeb muaj nyob rau hauv ntau yam daim ntawv xws li khoom khov kho, ventilated, ntaiv-hom, lossis ua ke trays. Lo lus "hlau hlau raceway" feem ntau hais txog cov hlau kaw trough-hom cable trays (uas yuav raug npog) tsim nyog rau kev tso cov xov hlau thiab cables. Vim lawv lub plhaub hlau kaw muab qee qhov kev ua tau zoo shielding, lawv feem ntau siv rau cov voj voog qis-voltage lossis cov kab tswj.
