Cable Npav GOST, seev suab thiab designations

cable npav - yog siv cov daim nyias nyias ntawm txawv xim, thov ntawv, cov kev siv ntawm daim ntawv thiab cov cim npe, raws li zoo raws li hluav taws xob npiv zas. Lub marker qhia tau hais tias lub cable yam ntxwv thiab tso cai rau kom faib nws cov lwm tus xws li cov.

Yuav ua li cas yog cov hnub nyoog xws ntawm tej?

Npav hwj chim cables muaj cov tsiaj ntawv denoting cov khoom uas lub plhaub, rwb thaiv tsev, neeg xyuas pib, thiab lub hom ntawm kev tiv thaiv. Cim nrog ib tug high voltage cables muaj xws li tsim nta.

Tooj nyob ntawm tej nyob rau hauv lub inscription yog tsis cim los ntawm ib tug tshwj xeeb tsab ntawv. Feem ntau, lub txhuas xyuas pib - yog tsab ntawv "A", uas sawv ntawm thaum pib ntawm lub npav. Ces muaj ib tsab ntawv uas qhia txog cov rwb thaiv tsev ntaub. Polyethylene rwb thaiv tsev - tsab ntawv "P", PVC qhia los ntawm tsab ntawv "B", thiab cov roj hmab foob tso cai los ntawm tsab ntawv "P". Nram qab no yog ib tsab ntawv qhia hais tias lub hom containment, namely tsab ntawv "A" - txhuas, tsab ntawv "C" - lead, tsab ntawv "P" - PE hose, tsab ntawv "B" - ib tug plhaub ntawm polyvinyl tshuaj dawb, roj hmab plhaub - tsab ntawv "P" . Tsis ntev los no cov tsiaj ntawv sawv ntsug cover hom.

Piv txwv li, lub npe "SG" yog ib tug tooj liab hlau, ntawv rwb thaiv tsev, ua sheath, tsis muaj kev tiv thaiv npog. Roj puv cable npav comprises ib tsab ntawv "M" (gas siab - tsab ntawv "G") thiab tsab ntawv signifying roj siab yam ntxwv thiab lwm yam nta. Piv txwv li, "MHC" cable - nws yog roj puv cable, tsis tshua muaj siab, thiab txhuas cladding, uas muaj ib tug tiv thaiv cover.

Npav nyob ntawm tej thiab cables yog nqa tawm los ntawm tus xov tooj thiab cov tsiaj ntawv nyob rau lub xeev cov qauv thiab specifications: GOST 16442-80 thiab TU16.71-277-98.

Siv cov tsiaj ntawv ua ke nrog cov zauv

Tsis tas li ntawd muaj yog ib qho alpha-numeric cable npav. transcript:

• AVVGng 3x4 - peb-hlau cable, txhuas. Nrog 4 square seem. Lub casing thiab rwb thaiv tsev muaj polyvinylchloride, ib tug tiv thaiv cover yog tsis tam sim no, nws tsis txhawb combustion.

• ASB 7x2.5 - xya-pin keyed cable, txhuas. Section C - 2.5 square. Lub plhaub yog ua los ntawm cov hlau lead, muaj tej cuab yeej.

Hais tias yog, xws li ib tug daim ntawv lo qhia tus ntoo khaub lig seem thiab lawv muaj pes tsawg.

Deciphering tshwj xeeb abbreviations

Npav nyob ntawm tej thiab cables, uas muaj ib tug mob siab acronym:

• KSPV - cables yog npaj rau tshwj xeeb kis tau tus mob systems nyob rau hauv lub plhaub.
• KPSVV - cables yog npaj rau hluav taws kub tswb.
• KPSVEV - cables yog npaj rau hluav taws kub alarms, tab sis lawv muaj xws li cov kev tshuaj ntsuam.
• PNSV - cua kub cable nrog ib tug hlau tub ntxhais.
• MF-1, MF-3 - hlau nrog rwb thaiv tsev yas. Qhov yooj ntawm cov leeg - 1.3 chav kawm ntawv.
• PVA - hlau muaj ib tug yas plhaub (connector).

Tsis zoo li cov khoom los ntawm txhua lwm yam los ntawm ib tug txawv xim tswvyim

Peb yuav tsum paub qhov txawv nruab nrab ntawm lawv rau kev siv ntawm cables. Yuav kom ua tau qhov no yooj yim, yog ib cov xim cable npav.

Rau kev qhia kom paub txog cables siv xim av, dub, liab, daj, txiv kab ntxwv, ntsuab, liab doog xim. Thiab xiav, dawb, grey, turquoise thiab liab. Qhov no daim ntawv teev yog teem los ntawm lub xeev tus qauv.

Blue hlau yog npaj rau nruab nrab los yog nruab nrab neeg xyuas pib.

Tej zaum lawv yuav sib txawv ob peb ua ke ntawm cov xim. Ntsuab thiab daj xim yuav siv tsis tau nyob rau hauv lwm yam ob peb ua ke tshaj lub ua ke ntawm daj thiab ntsuab, thiab nws yog siv los txhais ib tug tiv nruab nrab neeg xyuas pib.

Yog hais tias tus tiv thaiv lub ntiaj teb ua ke nrog rau cov neeg xyuas pib - qhia yog tag nrho ntev ntawm lub daj-ntsuab ua ke, thiab rau hauv lub xaus ntawm lub teeb xiav los yog lub teeb xiav tshaj tag nrho ntev thiab rau hauv lub xaus ntawm lub ua ke ntawm daj thiab ntsuab.

Piv txwv ntawm kev qhia kom paub txog cores:

1. Xim qhia kom paub txog conductors, uas yog insulated PVC compound:

- peb-hlau cable: dub, xiav, xim av los yog ib tug ua ke ntawm daj thiab ntsuab, dub, xiav;

- plaub-core cable: Lub ua ke ntawm daj thiab ntsuab (tiv thaiv lub ntiaj teb neeg xyuas pib), dub, xiav, xim av.

2. Xim cim muaj nyob kuj rau peb ib leeg-core cables, pleev xim rau dub:

- ib tug cable muaj ib tug xiav daim ntawv lo;

- ib zaug xwb cable uas tsis muaj daim ntawv lo los yog daim ntawv lo dub;

- ib tug cable muaj ib tug xim av xim daim ntawv lo.

3. Xim qhia kom paub txog kev haumxeeb tseem ceeb chains:

- rau conductors muaj lub hwj chim circuits, nws yog dub;

- rau conductors, muaj cov kev tswj Circuit Court, tswb thiab ntsuas tam sim no uas yog nce mus nce los, yog liab;

- rau conductors, muaj cov kev tswj Circuit Court signaling thiab DC ntsuas yog xim xiav;

- rau kev tiv thaiv conductors ntawm xoom - ib tug ua ke ntawm daj thiab ntsuab;

- rau conductors uas muaj kev cob cog rau hauv nruab nrab neeg xyuas pib thiab yog tsis npaj rau lub ntiaj teb - nws yog ib lub xiav.

Cov cim npe siv rau daim ntawv lo

Tags khij cable yog siv rau npav ntawm tswj thiab lub hwj chim nyob ntawm tej. Lawv yog ua los ntawm polypropylene.

Yog hais tias muaj yog muab zais xov cables los yog kav dej nyob rau hauv lub phab ntsa, npav cim npe uas txuas mus rau lub cable qhov hluav taws xob thiab cov inlet, nyob rau hauv cov qhov dej thiab kav dej phwj lag thaiv thiab hlws ris lub thawv. Nyob rau hauv cov ntaub ntawv ntawm cable routing daim ntawv lo cim npe teev nyob rau hauv txhua lub thawv, los yog coupler, thiab nyob rau thaum xaus. Nyob rau hauv thiaj li yuav nruab ib lub cable nyob rau hauv ntub chaw, ntawv yog ua los ntawm cov yas.

Tags yog:

- Cable Npav U-134;

- Cable Npav U-153;

- Cable Npav U-135;

- Cable Npav U-136.

Council

Yog li ntawd, raws li koj tau pom los ntawm qhov tsab xov xwm, npav hlau thiab cable (los ntawm txoj kev, GOST, yog ib yam dab tsi uas yuav tsum xub xyuam xim rau cov neeg ntawm purchase) heev varied. Thiab lub nruab nrab tus neeg yuav tsis yooj yim los daws kom tau qhov no. Yog li ntawd peb yuav muab tswv yim rau kev ua hauj lwm nrog cables thiab nyob ntawm tej rau chaw uasi mus rau kev pab. Nws yuav zoo yog hais tias nyob rau hauv cov kev pab cuam ntawm tus tswv yuav tsis yog tus tsim nyog ua hauj lwm, tab sis kuj cov purchase ntawm qhov tsim nyog cov ntaub ntawv uas, yog li ntawd koj ua tsis mess up. Yog hais tias koj txiav txim siab rau nws tus kheej-ua tej yam hauj lwm uas txuam nrog cables thiab nyob ntawm tej, nws yog tsim nyog los xav koj hmoov nyob rau hauv no nyuaj teeb meem!
