LV cable hais txog cov kab hluav taws xob qis
MV cable hais txog qhov nruab nrab voltage cable
Qhov sib txawv feem ntau suav nrog cov hauv qab no:
1, Voltage theem
LV cable : feem ntau yog hais txog cov cables uas muaj qhov ntsuas hluav taws xob ntawm 1 kV lossis qis dua, thiab cov ntsuas hluav taws xob muaj xws li 220V, 380V, thiab lwm yam. Cov cables no feem ntau yog siv hauv cov tshuab hluav taws xob tsawg.
MV cable: ib lub cable nrog qhov ntsuas hluav taws xob ntawm 1 kV thiab 35 kV. Lawv feem ntau yog siv rau hauv qhov chaw uas yuav tsum tau muaj qhov hluav taws xob siab, xws li kev faib hluav taws xob hauv nroog, kev lag luam thiab kev lag luam mining, thiab cov tsev loj.
2, Daim ntawv thov teb
Tsis tshua muaj hluav taws xob cable: Vim lawv cov qib qis voltage, low-voltage cables tau dav siv hauv cov khoom siv hluav taws xob me me thiab cov khoom siv teeb pom kev zoo xws li cov tsev, chaw ua haujlwm, cov tsev lag luam, nrog rau cov khoom siv hluav taws xob tsawg.
Nruab nrab voltage cable: Vim lawv cov high voltage theem thiab muaj peev xwm kis tau tus mob, nruab nrab voltage cables feem ntau yog siv nyob rau hauv tej qhov chaw uas yuav tsum tau loj npaum li cas ntawm lub hwj chim kis tau tus mob thiab tis, xws li lub nroog fais fab kev sib txuas, industrial cheeb tsam, loj tsev, thiab underground highways.
3, Cov ntaub ntawv tsim qauv
LV cable: Cov qauv yog qhov yooj yim, feem ntau yog tsim los ntawm cov conductors, rwb thaiv tsev txheej, sheaths, thiab lwm yam. Cov khoom siv hluav taws xob feem ntau yog ua los ntawm tooj liab lossis txhuas, thiab txheej rwb thaiv tsev feem ntau yog ua los ntawm cov ntaub ntawv xws li polyethylene thiab cross-linked polyethylene. Cov txheej rwb thaiv tsev ntawm cov hluav taws xob qis qis yog qhov nyias nyias, ua rau cov nqi tsim khoom qis dua.
MV cable: Cov qauv yog qhov nyuaj, thiab tus neeg xyuas pib hla ntu feem ntau siab dua 10kV. Nws yog feem ntau yog tsim los ntawm ntau yam stranded liab qab tooj liab los yog liab qab txhuas conductors. Txhawm rau txhim kho kev ua haujlwm rwb thaiv tsev, cov khoom siv hluav taws xob nruab nrab feem ntau siv ob txheej lossis peb txheej txheej rwb thaiv tsev, suav nrog txheej txheej semiconductor, cov txheej txheem siab-voltage silicone roj hmab rwb thaiv tsev txheej, lossis txheej thermoplastic epoxy rau optical cables. Tsis tas li ntawd, cov kab hluav taws xob nruab nrab yuav muaj cov txheej txheem hlau tiv thaiv ntxiv rau sab nrauv los tiv thaiv kab.
4, Kev ua haujlwm zoo
Tsis tshua muaj hluav taws xob cable: tsis tshua muaj hluav taws xob theem, tab sis zoo kab kev ruaj ntseg, tsis tshua muaj kev sib kis tsis zoo, thiab kev pab lub neej ntev. Vim nws cov nqi tsim khoom tsawg, cov khoom siv hluav taws xob tsawg yog siv dav hauv ntau yam ntawm lub neej.
Nruab nrab voltage cable: Nws muaj cov yam ntxwv ntawm kev sib kis ntev, tsis tshua muaj kev sib kis, thiab muaj peev xwm thauj khoom loj. Txawm li cas los xij, vim nws cov qauv tsim thiab cov khoom siv siab, tus nqi ntawm cov khoom siv hluav taws xob nruab nrab yog qhov siab. Tab sis nws txoj kev ruaj ntseg thiab kev ntseeg siab hauv kev xa hluav taws xob thiab kev faib tawm kuj yog siab dua.
