Dab tsi yog hom high-voltage cables?

Hais txog high-voltage cables, peb txhua tus yuav tsum paub txog nws, tab sis peb kuj tseem tsis paub txog cov ntaub ntawv tseem ceeb ntawm cov khoom no. Qhov tseeb, high-voltage cable yog ib hom fais fab cable, uas yog hais txog lub hwj chim cable siv los xa tawm ntawm 1kv thiab 1000kv, thiab feem ntau yog siv rau kev xa hluav taws xob thiab kev xa tawm. Nws cov khoom siv yog tooj liab, aluminium, thiab steel core aluminium stranded hlau. Tus qauv siv thaum nws siv yog GB / T12706-2008, thiab qhov kub ntawm lub cuab yeej yog siab dua 0 ° C. Nws feem ntau yog siv ntawm qhov kub thiab txias ntawm 90 ° C. Nov yog qee cov ntaub ntawv yooj yim txog cov kab hluav taws xob siab. Ntawm no peb ntawm Shenyang Cable Factory tseem xav qhia cov phooj ywg tias nws muaj ntau yam? Qhov tseeb, muaj ntau hom high-voltage cables. Feem ntau peb muaj yog YJV cables, VV cables, YJLV cables, thiab VLV cables. Lub npe tag nrho ntawm YJV yog qhov tseeb XLPE insulated PVC sheathed zog. Lub npe tag nrho ntawm VV yog PVC insulated PVC sheathed zog, YJLV feem ntau hu nws XLPE insulated PVC sheathed aluminium core zog, VLV hu nws PVC insulated PVC sheathed aluminium core fais fab cable. Yog tias hom txawv, nws txoj haujlwm yuav txawv thaum lub sijhawm siv. Yav tom ntej, peb yuav tsum paub meej txog peb cov kev xav tau thaum yuav khoom.

Yog li ntawd, muaj ntau hom high-voltage cables. Vim tias qhov kev ua haujlwm zoo ntawm cov khoom siv tooj liab, tooj liab tub ntxhais fais fab cables tau siv los ua txoj hauv kev loj ntawm cov khoom siv hluav taws xob hauv ntau txoj haujlwm, thaum aluminium core fais fab cables siv tsawg dua. , tshwj xeeb tshaj yog nyob rau hauv lub zog hluav taws xob ntau dua, cov tub ntxhais tooj liab ntau dua raug xaiv. Cov qauv ntawm no high-voltage cable yog kuj yooj yim. Cov khoom tseem ceeb ntawm sab hauv mus rau sab nrauv muaj xws li tus neeg xyuas pib, rwb thaiv tsev, sab hauv sheath, muab tub lim, thiab txheej rwb thaiv tsev. Tau kawg, armored high-voltage cables feem ntau yog siv rau hauv av faus. Thaum siv, lawv tuaj yeem tiv taus lub zog siab squeezing rau hauv av thiab tiv thaiv kev puas tsuaj los ntawm lwm yam sab nraud. Yog li ntawd, nws qhov zoo kuj tseem meej heev. Feem ntau hais lus, qhov yuav tsum tau ua rau cov khoom no yog qhov siab thaum nws siv. Peb yuav tsum nrhiav cov chaw tsim khoom lag luam niaj hnub los yuav nws thaum peb yuav nws. Nyob rau hauv luv luv, high-voltage cables yog haum rau kev sib txuas lus nrog rated voltages ntawm 35KV thiab hauv qab no rau lub hwj chim kis tau tus mob thiab tis. Lub sij hawm ua hauj lwm kub ntawm lub cable conductor yog 90 degrees, thiab qhov kub ntawm lub cable conductor tsis tshaj 250 degrees.
