Cables yog ubiquitous nyob rau hauv niaj hnub lub neej thiab ntau lawm. Cov hluav taws xob uas peb siv hauv peb lub neej thiab cov tsheb uas peb tsav tsheb tsis tuaj yeem sib cais los ntawm ntau hom kab hluav taws xob.Yog li qhov sib txawv ntawm cov fais fab cables thiab tswj cables yog dab tsi, thiab peb tuaj yeem paub qhov txawv ntawm lawv li cas?
Tswj cable
Feem ntau, cables pib nrog tsab ntawv K yog tswj cables.Cables yuav muab faib raws li qhov yuav tsum tau ntawm kev siv ib puag ncig: zoo tib yam cables, nplaim hluav taws kub retardant cables, hluav taws-resistant cables, uas tsis muaj pa taws halogen-free cables, tsev kho kom zoo nkauj xov hlau, ntxhia. insulated cables, thiab lwm yam. Nyob rau hauv cov hluav taws xob muaj zog, cables muab faib ua: tswj cables, high-voltage cables thiab low-voltage cables.Tab sis nco ntsoov: tswj cables tsis xa cov teeb liab! Lawv ua tam sim no, thiab tam sim no ntws los ntawm cov tswj cable yog feem ntau hauv qab 5A, yog li qhov kev sib tw ntawm cov kab hluav taws xob tswj tau qis dua 2.5mm2.
Ua ntej tshaj plaws, peb tuaj yeem ua qhov sib txawv yooj yim ntawm cov duab, xim, thiab tus naj npawb ntawm cov cores:
Qhov sib txawv ntawm cov xim tseem ceeb: Cov xim ntawm cov tub ntxhais insulated ntawm cov kab hluav taws xob tswj feem ntau yog xim dub nrog cov ntawv dawb, thaum cov hluav taws xob qis hluav taws xob feem ntau yog xim xim.
1. Qhov sib txawv ntawm tus naj npawb ntawm cov cables:
Fais fab cables muaj tsawg cores, xws li ib tug tub ntxhais, ob cores, peb cores, plaub cores (peb-theem plaub-xaim system), thiab tsib cores (peb-theem tsib-xaim system). Raws li qhov yuav tsum tau muaj ntawm daim phiaj hluav taws xob, qhov siab tshaj plaws yog feem ntau yog tsib cores.Txawm li cas los xij, cov kab hluav taws xob tswj tau siv rau kev xa xov hluav taws xob tswj cov teeb liab muaj ntau cov cores, xws li los ntawm ob cores mus rau 61 cores los yog ntau tshaj.Control cables kuj siv ntau yam cores. , shielding, thiab lwm yam kev ntsuas kom ua tiav cov txiaj ntsig zoo ntawm electromagnetic compatibility.
2.Qhov txawv ntawm cov hlau sheaths:
Fais fab cables xav tau lub zog compressive txaus, tensile lub zog, kub tsis kam, thiab corrosion kuj nyob rau hauv cov hlau sheath.Control cables muaj qis dua.
kab hluav taws xob
Tom qab ntawd nws yog qhov txawv ntawm qhov kev ua tau zoo thiab kev siv hluav taws xob cables thiab tswj cables:
1. Qhov sib txawv hauv ntu ntu:
Fais fab cables yog thawj load conductors, thiab lub peev xwm nqa tam sim no nce nrog qhov nce hauv lub zog.Qhov hla ntawm tus neeg xyuas pib yuav tsum tau nce nrog qhov nce tam sim no.Yog li ntawd, cov specifications ntawm lub hwj chim cables feem ntau loj, mus txog 500 square meters. (qhov ntau yam uas cov tuam txhab ua lag luam tuaj yeem tsim tau). Cov tuam txhab tsim khoom uas tuaj yeem tsim cov hlaws loj dua yog qhov tsawg. Kev tswj cov kab hluav taws xob yog cov neeg siv hluav taws xob thib ob, uas tswj cov kev ua haujlwm tam sim no ntawm cov contactors thiab lwm yam khoom siv.Cov khoom siv tam sim no tsawg heev, thiab ntu ntu ntawm tus neeg xyuas pib yog qhov tsawg heev.Yog li ntawd, cov kab hluav taws xob hla ntawm cov kab hluav taws xob feem ntau me dua, nrog qhov siab tshaj plaws ntawm feem ntau tsis tshaj 10 square meters.
2. Qhov txawv ntawm qhov ntsuas voltage:
Qhov ntsuas hluav taws xob ntawm lub zog hluav taws xob feem ntau yog 0.6/1 kV thiab siab dua, thaum tswj cov kab hluav taws xob feem ntau yog 450/750 V.
3. Qhov sib txawv ntawm kev ua haujlwm:
Kev tswj cov kab hluav taws xob xa hluav taws xob ncaj qha los ntawm lub zog xa hluav taws xob ntawm lub zog hluav taws xob mus rau cov kab hluav taws xob sib txuas ntawm ntau yam khoom siv hluav taws xob thiab cov khoom siv hluav taws xob, thaum lub hwj chim cables feem ntau yog siv rau kev sib kis ntawm cov hluav taws xob muaj zog hauv kev tsim hluav taws xob, kev faib tawm, kev sib kis, kev hloov pauv. , thiab cov kab hluav taws xob. Vim tias qhov tam sim no loj dhau los ntawm lawv, cov kab hluav taws xob hluav taws xob tau siv nyob rau hauv cov kab tseem ceeb ntawm lub zog hluav taws xob xa mus thiab faib cov hluav taws xob hluav taws xob siab.
Thaum tsim muaj hluav taws xob fais fab cables thiab tswj cables ntawm tib yam specifications, lub rwb thaiv tsev thiab sheath thickness ntawm lub hwj chim cable yog thicker tshaj li ntawm cov tswj cable.Firstly, cov tswj cable belongs rau cov khoom siv hluav taws xob cable, uas yog ib qho ntawm tsib. Cov pawg loj ntawm cov cables.Tus qauv rau kev tswj cov cables yog 9330, thiab tus qauv rau cov fais fab cables yog GB12706.
