Cov hlau thiab cables yog cov khoom siv tseem ceeb hauv lub neej niaj hnub no. Lawv tau siv dav hauv hluav taws xob, kev sib txuas lus, kev tsim kho, kev thauj mus los thiab lwm yam kev lag luam. Lub luag haujlwm tseem ceeb ntawm cov xov hlau thiab cables yog xa hluav taws xob hluav taws xob thiab cov teeb liab, muab kev txhawb nqa yooj yim rau ntau yam. Muaj ntau hom cables. Cia peb kawm txog qhov sib txawv ntawm cov fais fab cables thiab tswj cables los ntawm cov nram qab no.
1. Cov qauv kev coj ua
Tus qauv siv rau kev tswj cables yog GB / T 9330-2008. Tus qauv rau fais fab cables yog GB/T 12706-2008.
2. Hlau core xim
Cov xim ntawm cov tub ntxhais insulated ntawm cov tswj cable feem ntau yog dub nrog cov cim dawb. Tsawg-voltage fais fab cables feem ntau yog xim-coded.
3. Muaj nuj nqi
Cov kab hluav taws xob tswj yog cov kab hluav taws xob sib txuas uas ncaj qha xa hluav taws xob hluav taws xob los ntawm qhov chaw faib hluav taws xob mus rau ntau yam khoom siv hluav taws xob. Fais fab cables feem ntau yog siv rau kev sib kis ntawm high-voltage hluav taws xob hluav taws xob nyob rau hauv tiam, tis, kis tau tus mob, transformation thiab fais fab mov kab. Tam sim no uas hla dhau yog loj. Cov kab hluav taws xob siv hluav taws xob yog siv los xa thiab faib cov hluav taws xob ua haujlwm loj hauv cov kab tseem ceeb ntawm lub zog hluav taws xob.
4. Tshooj
Fais fab cables yog thawj load conductors. Lub peev xwm nqa tau nce nrog qhov nce ntawm lub zog, thiab daim ntawv thov hla ntu ntawm cov neeg xyuas pib kuj yuav tsum tau nce nrog qhov nce ntawm tam sim no. Yog li ntawd, cov specifications ntawm lub hwj chim cables feem ntau loj. Cov kab hluav taws xob tswj yog cov xaim xaim thib ob, uas tswj cov kev ua haujlwm tam sim no ntawm cov khoom siv xws li contactors. Lub load tam sim no me me heev thiab cov xaim hla ntu yog qhov me me, yog li qhov hla ntawm kev tswj cable feem ntau me me.
5. Tus naj npawb ntawm cov cores
Tus naj npawb ntawm cov cores ntawm lub hwj chim cables yog me me, nrog rau ib tug tub ntxhais, ob cores, 3 cores, 4 cores (peb-theem plaub-xaim system), thiab 5 cores (peb-theem tsib-xaim system). Raws li qhov yuav tsum tau muaj ntawm daim phiaj fais fab, feem ntau yog 5 cores. Cov kab hluav taws xob tswj tau siv los xa cov teeb liab tswj thiab muaj ntau cov cores, xws li 2 cores mus rau 61 cores, lossis ntau dua. Cov kab hluav taws xob tswj kuj tseem siv ntau cov qauv hlau, thaiv thiab lwm yam kev ntsuas kom ua tiav cov txiaj ntsig zoo ntawm electromagnetic compatibility.
6. Rated voltage
Qhov ntsuas hluav taws xob ntawm cov hluav taws xob hluav taws xob feem ntau yog 0.6/1kV thiab siab dua, thiab cov kab hluav taws xob tswj feem ntau yog 450/750V.
7. Xov daim tawv nqaij
Fais fab cables xav tau cov hlau sheath kom muaj zog txaus compressive, tensile zog, kub tsis kam, thiab corrosion kuj. Tswj cable yuav tsum muaj tsawg. Thaum muaj hluav taws xob fais fab cables thiab tswj cables ntawm tib lub specification yog tsim, lub rwb thaiv tsev thiab sheath thickness ntawm lub hwj chim cable yog thicker tshaj li ntawm cov tswj cable.
