Raws li cov hluav taws xob voltage, lawv tuaj yeem muab faib ua nruab nrab thiab qis dua 1100 kv), KUB Voltage cables (1000 kV voltage cables (1000 kV voltage cables (1000 kv thiab saum toj thiab siab dua). Tsis tas li ntawd, lawv tuaj yeem muab faib ua AC thiab DC cables raws li tam sim no.
Raws li cov ntaub ntawv rwb thaiv tsev
1. Roj {{-} impregnated ntawv insulated fais fab cables:}}}}}} impregnegnated ntawv muaj keeb kwm ntev tshaj plaws ntawm kev siv. Lawv muaj kev nyab xeeb, txhim khu kev qha, muaj lub neej muaj kev pabcuam ntev, thiab pheej yig. Lawv cov teeb meem tseem ceeb yog qhov kev teeb tsa qhov txwv. Kev txhim kho ntawm txia - Dawb impregnegated ntawv rwb thaiv tsev tau daws cov ntawv siab qhov siab no tau daws cov cabnegnegnated cables los txuas ntxiv lawv siv thoob plaws.
2. Yas {- istulated fais fab cables: fais fab cables nrog ib tug extruded yas rwb thaiv tsev txheej. Feem ntau siv cov plastics suav nrog polyvinyl chloride, polyethylene, thiab hla}}} txuas Polyethylene. Yas cables ua ib tus qauv yooj yim, yooj yim rau kev tsim khoom thiab cov txheej txheem, yog ib qho yooj yim, thiab yooj yim rau nruab thiab pw yam tsis muaj kev teeb tsa qhov tsis txwv. Yog li ntawd, lawv tau dav siv rau nruab nrab thiab yog cov khoom siv voltage thiab yog cov khoom lag luam ntawm hloov cov roj viscous {}} impregnegnated ntawv cable. Nws cov drawback loj tshaj yog cov dendrite poob tshwm sim, uas txwv nws siv nyob rau ntawm ntau zog.
3. Roj hmab {{- Insulated txheej cable, uas tau muab sib xyaw ua ke nrog ntau yam sib xyaw ua ke, thiab tom qab ntawd kub {2} {vulcanized. Nws yog mos thiab yoog tau, ua rau nws haum rau kev teeb tsa nrog nquag txav thiab me me radii.
Cov roj hmab sib txuas siv rau rwb thaiv tsev muaj rau cov roj hmab muaj roj hmab- butadiene roj hmab roj hmab, thiab roj hmab butyl.
Kev faib tawm los ntawm cov qib voltage:
1. Tsawg {{- voltage cable: haum rau taag teeb thiab faib cov kab nrog lub ntsuas hluav taws xob ntawm 3kv thiab hauv qab, rau kev xa lub zog.
2. Nruab nrab - thiab qis {{{{{{{{{} {}}}} Txuas Polyethylene insulated cables, thiab lwm yam.
3. High {{{- voltage cables: (feem ntau 110kv thiab saum toj no): PE Cables {}}} Txuas Polyethylene insulated cables, thiab lwm yam.
4. Ultra - high- - ultra-siab voltage cable: (1000kv thiab saum toj no).
