Hlau thiab Cable Specifications

Hlau thiab cable specifications yog qhov tseem ceeb rau kev ua kom muaj kev xaiv kom raug thiab siv cov cables hauv ntau lub tshuab hluav taws xob. Nov yog qee qhov tseem ceeb ntawm cov hlau thiab cable specifications.

1. Tus neeg tsav tsheb loj
   1. Hla-Sectional Area: Qhov chaw hla ntu ntawm tus neeg xyuas pib yog qhov tseem ceeb, uas feem ntau qhia hauv square millimeters (mm²) lossis ncig mils. Qhov loj dua ntawm qhov chaw hla ntu, qhov qis dua qhov tsis kam ntawm tus neeg xyuas pib thiab qhov muaj peev xwm nqa tam sim no ntau dua. Piv txwv li, ib qho khoom siv hluav taws xob hauv tsev yuav muaj thaj tsam ntawm 1.5 mm², 2.5 mm², lossis 4 mm², thaum lub zog xa hluav taws xob muaj zog tuaj yeem muaj thaj tsam loj dua.
   2. Txoj kab uas hla: Txoj kab uas hla ntawm tus neeg xyuas pib kuj yog ib qho tseem ceeb tshwj xeeb, tshwj xeeb tshaj yog rau qee qhov kev siv tshwj xeeb xws li coaxial cables lossis cov hlau zoo. Txoj kab uas hla ntawm tus neeg xyuas pib cuam tshuam qhov yooj yim thiab qhov chaw teeb tsa ntawm lub cable.
2. Cov khoom siv rwb thaiv tsev thiab Thickness
   1. Cov khoom siv rwb thaiv tsev: Cov ntaub ntawv rwb thaiv tsev sib txawv muaj cov khoom siv hluav taws xob sib txawv, qhov kub thiab txias, thiab tshuaj tiv thaiv. Piv txwv li, PVC rwb thaiv tsev yog dav siv nyob rau hauv tsawg-voltage cables vim nws tsis tshua muaj nqi thiab zoo hluav taws xob rwb thaiv tsev zog. XLPE rwb thaiv tsev muaj qhov zoo ntawm qhov kub thiab txias thiab hluav taws xob rwb thaiv tsev, yog li nws yog feem ntau siv nyob rau hauv high-voltage cables.
   2. Rwb thaiv tsev Thickness: Lub thickness ntawm rwb thaiv tsev txheej yog txiav txim los ntawm kev khiav hauj lwm voltage ntawm lub cable. Qhov siab dua qhov kev khiav hauj lwm voltage, lub thicker lub rwb thaiv tsev txheej yuav tsum tau ua kom lub rwb thaiv tsev hluav taws xob kev nyab xeeb ntawm lub cable. Tsis tas li ntawd, cov rwb thaiv tsev thickness kuj cuam tshuam rau qhov yooj thiab sab nraud ntawm lub cable.
3. Sheathing Material thiab Thickness
   1. Sheathing Khoom: Raws li tau hais ua ntej, cov khoom siv sheathing yog siv los tiv thaiv lub cable los ntawm kev puas tsuaj sab nraud. Kev xaiv ntawm cov khoom siv sheathing nyob ntawm qhov chaw teeb tsa thiab cov kev xav tau ntawm lub cable. Piv txwv li, hauv kev teeb tsa sab nraum zoov, cov khoom siv sheathing nrog zoo UV tsis kam thiab kev ua haujlwm tsis muaj dej yuav tsum tau ua. Hauv cov cheeb tsam uas muaj kev ntxhov siab, cov khoom siv sheathing nrog lub zog tensile siab thiab kev cuam tshuam tsis zoo yog xav tau.
   2. Sheathing Thickness: Lub thickness ntawm sheathing txheej kuj yog ib qho tseem ceeb parameter, uas cuam tshuam rau cov neeg kho tshuab kev tiv thaiv kev ua tau zoo thiab kev pab cuam lub neej ntawm lub cable. Ib txheej txheej tuab tuab tuaj yeem muab kev tiv thaiv zoo dua rau cov kab hluav taws xob, tab sis nws tseem yuav ua rau cov kab sab nraud thiab qhov hnyav, uas yuav cuam tshuam rau kev teeb tsa thiab siv cov cable.
4. Kev ntsuas hluav taws xob
   1. Rated Voltage: Qhov ntsuas hluav taws xob ntawm lub cable yog qhov siab tshaj plaws voltage uas lub cable tuaj yeem tiv taus tsis tu ncua thaum lub sijhawm ua haujlwm. Nws yog ib qho tseem ceeb parameter rau xaiv lub cable. Yog hais tias qhov kev khiav hauj lwm voltage tshaj qhov ntsuas hluav taws xob ntawm lub cable, nws yuav ua rau cov rwb thaiv tsev tawg thiab hluav taws xob raug mob.
   2. Voltage Classification: Raws li qhov sib txawv ntawm qhov sib txawv, cov cables tuaj yeem muab faib ua cov kab hluav taws xob qis (qis dua 1 kV), nruab nrab-voltage cables (1 kV txog 35 kV), high-voltage cables (35 kV txog 220 kV), thiab ultra- high-voltage cables (tshaj 220 kV).
5. Cable Ntev
   1. Txheem Length: Feem ntau cov cables yog tsim nyob rau hauv tus qauv ntev, xws li 100 meters, 500 meters, los yog 1000 meters. Tus qauv ntev yog yooj yim rau kev tsim khoom, kev thauj mus los, thiab kev teeb tsa. Txawm li cas los xij, rau qee qhov haujlwm tshwj xeeb, kev cai-ntev cables yuav xav tau.
   2. Ntev Ntev: Muaj qee qhov ntev ntev rau cov cables, uas feem ntau yog nyob rau hauv ib feem pua ​​​​ntawm cov nominal ntev. Qhov ntev ntev yuav tsum tau txiav txim siab thaum yuav khoom thiab siv cov cables los xyuas kom meej tias qhov ntev ntawm cov cable ua tau raws li qhov yuav tsum tau ua ntawm qhov project.
