Thaum lub sij hawm thaum ntxov ntawm kev tsim kho, overlooking cov kev ua tau zoo thiab rear-kawg load ntawm cables tej zaum yuav ua rau muaj teeb meem hluav taws kub. Niaj hnub no, kuv yuav tham txog 6 lub ntsiab lus tseem ceeb los txiav txim siab txog qhov ntsuas hluav taws kub tsis zoo ntawm cov xov hlau thiab cables hauv qhov project engineering tsim.
1. Cable Installation Ib puag ncig:
Ib puag ncig rau kev teeb tsa cable feem ntau txiav txim siab qhov tshwm sim ntawm cable raug rau cov hluav taws kub sab nraud thiab qhov sib kis tom qab hluav taws kub. Piv txwv li, cov cables ncaj qha faus los yog ib tus kav xa dej tuaj yeem siv cov kab hluav taws xob uas tsis yog hluav taws kub, thaum cov khoom tso rau hauv ib nrab kaw cable tais, trenches, lossis cov kab hluav taws xob tshwj xeeb tuaj yeem txo cov hluav taws kub nyhiab los ntawm ib mus rau ob theem. Nws raug nquahu kom xaiv rau Class C lossis txawm tias Class D hluav taws kub-retardant cables nyob rau hauv xws li ib puag ncig uas muaj kev cuam tshuam sab nraud, ua rau combustion tsawg dua thiab yooj yim rau nws tus kheej tua.
2. Qhov ntau ntawm Cables ntsia:
Qhov ntau ntawm cov cables cuam tshuam rau qib ntawm hluav taws-retardance. Tus naj npawb ntawm cov khoom siv tsis yog xim hlau nyob hauv tib qhov chaw txiav txim siab txog cov khoom hluav taws kub-retardant. Piv txwv li, nyob rau hauv cov xwm txheej uas fireproof boards cais ib leeg nyob rau hauv tib lub channel los yog lub thawv, txhua tus choj los yog lub thawv raug suav tias yog ib qho chaw cais. Txawm li cas los xij, yog tias tsis muaj kev sib cais ntawm cov no, thiab thaum muaj hluav taws tshwm sim, kev sib nrig sib cuam tshuam, uas yuav tsum tau suav nrog rau kev suav cov khoom siv hluav taws xob tsis yog xim hlau.
3. Cable Diameter:
Tom qab txiav txim siab qhov ntim ntawm cov khoom tsis yog xim hlau hauv tib lub channel, cov kab hluav taws xob sab nraud tau pom. Yog tias cov kab me me (hauv qab 20mm) ua tus thawj, txoj hauv kev nruj dua rau qhov hluav taws kub-retardance raug pom zoo. Piv txwv li, yog tias cov kab uas loj dua (tshaj 40mm) muaj ntau, qhov kev nyiam ntawm cov qib qis yog qhia. Cov kab me me nqus cov cua sov tsawg dua thiab yooj yim rau ignite, thaum cov loj dua nqus cua sov thiab tsis tshua muaj hluav taws xob.
4. Tsis txhob sib xyaw cov hluav taws kub-Retardant thiab Non-Fire-Retardant Cables nyob rau hauv tib Channel:
Nws yog qhov pom zoo rau cov cables nteg nyob rau hauv tib lub channel kom muaj qhov sib npaug lossis zoo sib xws ntawm cov hluav taws kub-retardant. Cov kab hluav taws xob qis lossis tsis muaj hluav taws kub tsis zoo 'post-ignition tuaj yeem ua raws li cov hluav taws kub sab nraud rau cov kab hluav taws xob siab dua, ua rau muaj peev xwm txawm tias Class A hluav taws kub-retardant cables ntes hluav taws.
5. Txiav txim siab qhov hluav taws kub-Retardant Level raws li qhov tseem ceeb ntawm qhov project thiab qhov tob ntawm qhov hluav taws kub phom sij:
Rau tej yaam num loj xws li skyscrapers, banking thiab nyiaj txiag cov chaw, loj los yog ntxiv-loj venues nrog concentrated neeg coob coob, siab dua hluav taws-retardant theem raug pom zoo nyob rau hauv cov xwm txheej zoo sib xws. Cov pa luam yeeb tsawg, tsis muaj halogen, hluav taws kub-resistant cables raug pom zoo.
6. Kev sib cais ntawmFais fab thiab tsis muaj zog cables:
Cov kab hluav taws xob muaj hluav taws xob ntau dua thaum lawv ua haujlwm hauv lub xeev uas muaj cua sov uas muaj peev xwm ua rau luv luv-circuit breakdowns. Tswj cov kab hluav taws xob, muaj qhov tsis tshua muaj hluav taws xob thiab cov khoom me me, nyob twj ywm txias thiab tsis tshua muaj hluav taws xob. Yog li ntawd, nws tau qhia kom cais lawv nyob rau hauv tib qhov chaw, nrog lub hwj chim cables saum toj no, tswj cables hauv qab no, nrog fireproof cais ntsuas nyob rau hauv nruab nrab los tiv thaiv hlawv cov khib nyiab los ntawm poob.
ONEWORLD muaj kev paub ntau xyoo hauv kev muab khoomcable raw khoom, pab cable manufacturers thoob ntiaj teb. Yog hais tias koj muaj tej yam yuav tsum tau rau hluav taws-retardant cable raw cov ntaub ntawv, thov koj xav tiv tauj peb.
