High voltage hlau xaim
High-voltage cable yog ib hom ntawm lub hwj chim cable, uas hais txog lub hwj chim cable siv rau kis ntawm 10kv-35kv (1kv = 1000v), thiab feem ntau siv nyob rau hauv txoj kev tseem ceeb ntawm kev xa xov hluav taws xob. Cov kev cai siv khoom tsim rau cov xov tooj hluav taws xob siab yog gb / t 12706.2-2008 thiab gb / t 12706.3-2008
Cov hom hluav taws xob hauv siab
Cov hom tseem ceeb ntawm high-voltage cables yog yjv cable, vv cable, yjlv cable, thiab vlv cable.
yjv cable tag nrho lub npe XLPE insulated PVC sheathed fais fab cable (tub ntxhais tooj liab)
Lub npe ntawm tag nrho cov hlua cable yog PVC insulated thiab sheathed fais fab cable (tub ntxhais tooj liab)
yjlv cable tag nrho lub npe XLPE insulated PVC sheathed aluminium tub ntxhais lub zog hluav taws xob
VLV cable tag nrho lub npe PVC insulated PVC sheathed aluminium tub ntxhais fais fab cable
Vim tias qhov zoo tshaj plaws hluav taws xob kev ua haujlwm ntawm tooj liab conductors, ntau thiab ntau txoj haujlwm siv tooj liab cov tub luam hluav taws xob ua txoj kev loj ntawm txoj kev xa hluav taws xob, thaum txhuas cov tub ntxhais siv hluav taws xob siv hluav taws xob tsawg dua, tshwj xeeb tshaj yog cov hluav taws xob ntau hluav taws xob, xaiv tooj liab tub ntxhais. Cov cables ntau muaj.
Cov qauv ntawm high-voltage cables
Cov khoom siv ntawm cov hluav taws xob hluav taws xob txuas ntxiv los ntawm sab hauv rau sab nraud suav nrog: tus neeg xyuas pib, rwb thaiv tsev, sab hauv sheath, muab tub lim (cov cuab yeej ua rog), thiab txheej sab nraud. Ntawm chav kawm, lub ntsej muag hluav taws xob high-voltage cables feem ntau yog siv rau kev sib faus hauv av, tuaj yeem tiv taus lub siab lub zog siab rau hauv av thiab tiv thaiv kev puas tsuaj los ntawm lwm lub zog sab nraud.

Kev siv high voltage cable siv cov yam ntxwv
Cov khoom no haum rau AC rated voltage 35kv thiab hauv qab rau kev xa xov hluav taws xob thiab kev faib tawm. Qhov siab tshaj plaws ua hauj lwm kub ntawm txoj kab hluav taws xob cable yog 90 degrees, thiab qhov kub siab tshaj plaws ntawm tus neeg xyuas pib cable tsis dhau 250 degrees thaum luv luv (lub sijhawm ntev tshaj plaws tsis tshaj 5s).
UHV cable
1kv thiab hauv qab yog cov xov hluav taws xob tsawg; 1kv ~ 10kv yog nruab nrab voltage cables; 10kv ~ 35kv yog cov xaim hluav taws xob loj; 35 ~ 220kv yog UHV cov xov hluav taws xob;
UHV cable yog ib hom ntawm cov xaim hluav taws xob uas tau tshwm sim nrog txoj kev loj hlob txuas ntxiv ntawm cov thev naus laus zis thev naus laus zis. UHV cable feem ntau siv ua lub hauv nruab nrab hauv qhov loj loj ntawm lub zog xa hluav taws xob. Nws yog cov hluav taws xob high-voltage cable nrog cov ntsiab lus kev qhia siab thiab yog siv rau lub zog ntev ntev kis.
Ua rau muaj qhov ntsuas hluav taws xob high voltage
Txoj kab txuas yog qhov txuas nruab nrab ntawm cov khoom siv hluav taws xob thiab cov cuab yeej hluav taws xob, thiab ua lub luag haujlwm ntawm kev xa cov khoom siv hluav taws xob. Nws yog dav siv, yog li kev ua tsis tiav feem ntau tshwm sim. Hauv qab no yog kev qhia luv luv ntawm cov laj thawj ntawm cov teeb meem tshwm sim ntawm cov hluav taws xob hluav taws xob hluav taws xob. Raws li cov laj thawj uas ua tsis tiav, lawv tau ntxig faib rau cov hauv qab no: cov khoom lag luam tsim kev tsim tawm, kev tsim kho kev tsim kho zoo, tsim cov qauv tsim, vim li cas sab nraud quab yuam ua kom puas plaub pawg.
