Raws li theem voltage
Raws li qib hluav taws xob, nws tuaj yeem faib ua nruab nrab thiab tsis tshua muaj hluav taws xob cov xaim hluav taws xob (35 kV thiab qis dua), muaj cov xaim hluav taws xob ntau (110 kV thiab siab dua), muaj cov xaim hluav taws xob ntau (275 txog 800 kV) thiab UHV cable (1000 kV thiab sab saud). Tsis tas li ntawd, nws muaj peev xwm raug faib ua AC cables thiab DC cable raws li cov kab ke tam sim no.
Dej num los ntawm cov khoom siv rwb thaiv tsev
1. Cov roj-impregnated ntawv-insulated fais fab cable yog insulated fais fab cables nrog roj-impregnated ntawv. Nws cov keeb kwm siv yog qhov ntev tshaj. Nws muaj kev nyab xeeb thiab txhim khu kev qha, muaj lub neej ua haujlwm ntev thiab tsis tshua muaj nqi. Lub ntsiab tsis zoo yog tias kev tso npe yog txwv los ntawm txoj kev poob. Txij li thaum txoj kev txhim kho tsis muaj txia impregnated daim ntawv rwb thaiv tsev, qhov teeb meem ntawm txoj kev poob qis tau daws teeb meem, yog li cov roj-impregnated ntawv insulated cable tuaj yeem siv txuas ntxiv.
2. Yas insulated fais fab cable Kab rwb thaiv tsev txheej yog extruded yas fais fab cable. Cov nquag plastics siv yog polyvinyl chloride, polyethylene, thiab cross-linked polyethylene. Cov kab xev yas muaj cov qauv yooj yim, kev tsim khoom yooj yim thiab kev hloov pauv, lub teeb yuag, kev tso yooj yim thiab kev teeb tsa, thiab tsis txwv los ntawm kev tso qis. Yog li ntawd, nws tau dav siv raws li nruab nrab thiab qis voltage cable, thiab muaj nyiam hloov cov roj viscous-impregnated roj-cov ntawv hluav taws xob. Nws qhov teeb meem loj tshaj yog qhov muaj hav zoov ntawm tsob ntoo tawg, uas txwv nws txoj kev siv ntawm qhov siab dua.
3. Cov roj hmab insulated fais fab cable: txheej txheej insulating yog ua los ntawm roj hmab ntxiv ntau cov kab mob sib xyaw ua ke, uas muaj kev sib xyaw thiab sib xyaw ntawm cov tub ntxhais conductive, thiab tom qab ntawd rhuab thiab vulcanized. Nws yog muag thiab yoog raws, thiab haum rau qee zaus nrog kev tshem ntau zaus thiab lub vojvoog me me.
Cov ntaub ntawv siv roj hmab feem ntau siv rau kev rwb thaiv tsev muaj xws li ntuj roj hmab-styrene butadiene roj hmab sib xyaw, ethylene propylene roj hmab, butyl roj hmab thiab lwm yam.
Raws li theem voltage
1. Cov kab hluav taws xob qis: haum rau kev nteg teeb ntawm lub hwj chim sib kis thiab xa tawm kab nrog AC 50Hz, ntsuas voltage 3kv thiab hauv qab rau kev xa xov fais fab.
2. Cov kab hluav taws xob nruab nrab thiab tsis tshua muaj hluav taws xob: (feem ntau hais txog 35KV thiab hauv qab): PVC insulated cables, polyethylene insulated cables, cross-linked polyethylene insulated cables, thiab lwm yam.
3. High-voltage cables: (feem ntau 110KV thiab sab saud): polyethylene cables thiab cross-linked polyethylene insulated cables, thiab lwm yam.
4. Ultra-siab voltage cable: (275 ～ 800KV).
5. UHV cables: (1000KV thiab sab saud).
