Raws li kev txawj ntse hauv zej zog tau dhau los ua neeg nyiam, cov xov hlau niaj hnub zoo li tib neeg lub paj hlwb, txuas mus rau txhua lub ces kaum ntawm lub tsev.
Txhua zaus txhua tus ua ib qho engineering lossis project, lawv tsuas xav tias: Yuav siv pes tsawg tus qauv hauv qhov project no?Yuav siv pes tsawg meters ntawm cable?
Muaj ntau cov qauv hlau thiab cable, tab sis lawv cov hluav taws kub tsis kam thiab cov nplaim hluav taws kub hnyiab tau raug tsis quav ntsej los ntawm tib neeg, uas tau dhau los ua qhov phom sij loj ntawm hluav taws.
Yog li yuav ua li cas xaiv qhov hluav taws kub tsis kam thiab nplaim hluav taws retardant qib ntawm cov xov hlau thiab cables hauv qhov project engineering tsim?Kab lus no muab cov lus qhia hauv qab no rau koj siv:
Cable tso ib puag ncig
Lub cable tso ib puag ncig txiav txim siab txog qhov tshwm sim ntau npaum li cas cable yuav raug tawm tsam los ntawm cov hluav taws kub sab nraud thiab muaj peev xwm ua kom qeeb combustion thiab kev puas tsuaj tom qab hluav taws.
Piv txwv li, cov kab hluav taws xob tsis muaj zog tuaj yeem siv rau kev faus ncaj qha lossis cov kav dej sib cais (hlau, asbestos, cov kav dej cement).
Yog hais tias lub cable yog muab tso rau hauv ib tug semi-kaw choj, trunking los yog tshwj xeeb cable trench (nrog ib tug cover), cov nplaim retardant yuav tsum tau tsim nyog txo los ntawm ib mus rau ob theem.Nws raug nquahu kom siv cov nplaim hluav taws kub retardant Class C lossis nplaim hluav taws kub retardant Class D.
Vim tias tsis tshua muaj kev cuam tshuam los ntawm lwm yam hauv ib puag ncig, txawm tias nws ntes hluav taws vim qhov chaw nqaim thiab occluded, nws yooj yim rau nws tus kheej tua thiab tsis tshua muaj tshwm sim. a kev puas tsuaj.
Ntawm qhov tsis sib xws, cov nplaim hluav taws kub hnyiab yuav tsum tau nce kom tsim nyog yog tias qhov hluav taws kub tawm sab hauv tsev, yog tias chav tsev tau nce los ntawm lub tsev, lossis hauv qhov chaw zais cia, mezzanine, lossis tunnel txoj kev hauv tsev, qhov chaw uas tib neeg cov kab thiab hluav taws tuaj yeem nkag tau yooj yim. qhov chaw yog qhov loj thiab cov huab cua tuaj yeem ncig tau yooj yim.Nws raug nquahu kom xaiv cov nplaim hluav taws kub retardant chav B lossis txawm tias nplaim hluav taws retardant chav kawm A.
Thaum qhov chaw nyob saum toj no nyob rau pem hauv ntej los yog tom qab lub qhov cub kub kub los yog nyob rau hauv ib qho hluav taws kub thiab tawg tshuaj lom neeg, roj av, los yog kuv ib puag ncig, nws yuav tsum tau ua nruj me ntsis, thiab nws yog qhov zoo dua kom siab tshaj qhov qis.Nws raug nquahu kom siv cov nplaim hluav taws kub retardant Class A, lossis halogen-dawb cov pa taws tsis muaj pa taws thiab hluav taws-resistant Class A.
Muaj pes tsawg cables tso?
Tus naj npawb ntawm cov cables cuam tshuam cov nplaim hluav taws kub ntawm cov kab hluav taws xob.Nws yog qhov tseem ceeb ntawm cov khoom tsis yog xim hlau hauv tib qhov chaw uas txiav txim siab txog qib ntawm cov nplaim hluav taws.
Thaum xam qhov ntim ntawm cov khoom tsis yog xim hlau ntawm cov xov hlau thiab cables, lub tswv yim ntawm tib qhov chaw yog hais txog cov nplaim hluav taws xob thaum nws ntes hluav taws.Los yog qhov chaw uas cov cua sov tuaj yeem ua rau tsis muaj kev cuam tshuam rau cov xov hlau thiab cov kab hluav taws xob nyob ze thiab tuaj yeem cuam tshuam rau lawv.
Piv txwv li, rau trusses los yog trough thawv nrog hluav taws-pov thawj boards uas yog cais los ntawm ib leeg, tib channel yuav tsum xa mus rau txhua tus choj los yog trough box.
Yog tias tsis muaj hluav taws kub sib cais saum toj no, hauv qab lossis sab laug thiab sab xis, thaum muaj hluav taws kub sib cuam tshuam rau ib leeg, cov khoom siv hluav taws xob tsis yog hlau yuav tsum sib npaug nrog rau kev suav.
Cable thickness
Tom qab qhov ntim ntawm cov khoom tsis yog xim hlau nyob rau hauv lub cable nyob rau hauv tib lub channel yog txiav txim siab, saib ntawm lub sab nraud txoj kab uas hla, yog hais tias cov cables feem ntau me me (txoj kab uas hla hauv qab 20 hli), cov nplaim hluav taws yuav tsum tau soj ntsuam nruj me ntsis.
Ntawm qhov tsis sib xws, yog tias cov cables feem ntau loj (inch 40mm lossis ntau dua), cov nplaim hluav taws yuav tsum tau kho kom nruj dua.
Yog vim li cas yog cov cables nrog me me sab nraud diameters nqus cua sov tsawg thiab yooj yim rau ignite, thaum cables nrog loj txheej diameters nqus cua sov ntau thiab tsis haum rau ignition.
Tus yuam sij rau kev tsim hluav taws yog qhov kub hnyiab.Yog hais tias nws yog ignited tab sis tsis hlawv, hluav taws yuav tua nws tus kheej.Yog nws hlawv tab sis tsis tua, nws yuav ua rau muaj kev puas tsuaj.
Cov nplaim hluav taws kub hnyiab thiab tsis muaj nplaim hluav taws yuav tsum tsis txhob sib xyaw rau hauv tib lub channel
Cov nplaim hluav taws kub hnyiab ntawm cov xov hlau thiab cov kab hluav taws xob tso rau hauv tib lub channel yuav tsum zoo ib yam lossis zoo sib xws.Cov nplaim hluav taws txuas ntxiv ntawm cov kab hluav taws xob qis lossis tsis muaj nplaim hluav taws yog qhov hluav taws kub sab nraud rau cov kab hluav taws xob siab.Lub sijhawm no, txawm tias Class A nplaim hluav taws xob Cables kuj muaj peev xwm ntes hluav taws.
Qhov tob ntawm qhov hluav taws kub phom sij txiav txim siab hluav taws kub retardancy qib
Rau cables siv nyob rau hauv loj engineering tej yaam num, xws li units saum toj no 30MW, ultra-siab cov tsev, tsev txhab nyiaj thiab nyiaj txiag chaw, loj thiab ntau-loj neeg coob qhov chaw, thiab lwm yam., cov nplaim hluav taws kub retardant theem yuav tsum siab dua thiab nruj dua nyob rau hauv tib yam kev mob, thiab Nws raug pom zoo kom xaiv cov pa luam yeeb tsawg, tsis muaj halogen, hluav taws-resistant thiab nplaim hluav taws xob cable.
Cov kab hluav taws xob thiab cov kab hluav taws xob tsis muaj hluav taws xob yuav tsum tau muab cais tawm ntawm ib leeg
Hais txog hais lus, fais fab cables yog ib qho yooj yim mus ntes hluav taws vim hais tias lawv yog kub thiab muaj peev xwm ntawm short-circuit breakdown, thaum tswj cables thiab teeb liab tswj cables nyob rau hauv ib tug txias lub xeev vim tsis tshua muaj voltage thiab me me load, yog li ntawd lawv tsis yooj yim. ntes hluav taws.
Yog li ntawd, nws raug pom zoo tias lawv yuav tsum tau nruab rau hauv tib Qhov ob qhov chaw tau muab tso rau nyias, nrog rau lub hwj chim cable nyob rau sab saum toj thiab cov tswj cable rau hauv qab.Txij li thaum hluav taws kub nce mus, kev ntsuas hluav taws xob cais tau ntxiv rau hauv nruab nrab txhawm rau tiv thaiv cov khoom siv hluav taws xob los ntawm kev tawg.
