ASB cable: nta, pricing, seev suab
Installation nyob rau hauv tej ib feem ntawm cov chaw zov thiab av tej yam kev mob cia kuv tso lub cable ASB, deciphering acronyms uas nyeem raws li nram no:
A - yog lub txhuas kev nyob ntawm tej;
C - lead sheath;
B - ntxiv steel kev tiv thaiv.
Koj muaj peev xwm ua tau raws li ib tug ntau yam - ib tug khoom nrog ib tug los ASBl. Nyob rau hauv no cov ntaub ntawv "L" - bitumen noj, uas yog nyob rau hauv lub tej cuab yeej.
Muaj ntau ntau yam ntawm lub hwj chim cables. Yog li ntawd, mus rau lub ntsiab tsab ntawv code yuav muab ntxiv ntxiv, xws li "Standby" nyob rau hauv lub koov txhais tau tias ib tug hlab ntsha.
daim ntawv thov
Yuav kom hloov fais voltage nrog ib zaus ntawm 50 Hz thiab ib tug voltage ntawm 1 mus rau 10 kV yog thov CRS cable.
tej yam kev mob rau kev tsim kho
Khiav lag luam CRS cable, uas raws li GOST 18410-73, yuav ua tau nyob rau hauv txawv tej yam kev mob: nyob rau hauv ib feem ntawm lub tsev thiab rau ntawm qhov chaw ntawm lub phab ntsa. Nws yuav hu ua universal, vim hais tias nws tsis yog ntshai ntawm huab kub. Lawv ntau yam yuav ua tau -50 ... + 50 degrees, cov av noo muaj peev xwm mus txog mus txog 98%. Nws installation yog ua nrog pes tsawg cua kub txawm tsis muaj preheating.
Cia permissible cua kub rau 70 degrees thaum lub sij hawm kev lag luam, mus txog 90 degrees - nyob rau hauv lub thaum muaj xwm ceev hom, luv luv-Circuit Court, nws yog tau withstand 200 degrees.
Warranty lub sij hawm ntawm lub lag luam ntawm 5 xyoo, thiab cov kev pab cuam lub neej tshaj 30 xyoo. Muab khoom qhib qhov yuav ua tau tsis muaj ntau tshaj li 2 xyoos, nyob rau hauv kev tsim kho ntawm ib tug toj - 5 xyoo, nyob hauv ib tug ntiav Tshuag - 10 xyoo. Generalized cov ntaub ntawv nyob rau hauv qhov hluav taws xob cable ASB, uas nws kev yam ntxwv tau raug xam, yuav muaj tuaj raws li ib lub rooj.

khoom tsim
Lub hwj chim module muaj tsev nyob tsis pub dhau lub compressed raj ntawm cov hlau lead. Kev tiv thaiv ntawm lub bitumen xav tau los mus tiv thaiv hlau xeb, qhov teeb meem qub yog polyethylene terephthalate fiber ntau thiab Crepe ntawv.
Yus nta qhab nia CRS ASBl yog lawv daim ntawv thov nyob rau hauv tsawg thiab nruab nrab xau xeb kev ua si nrog ib tug tseem ceeb muaj nuj nqis ntawm nws cov hom khoom uas ASB2l.
Yuav ua li cas nws muaj?
ASB cable muaj cov nram qab no hais:
- Lub plawv - conductive nyob ntawm tej ntawm ib los yog ntau tshaj ntawm tej ua los ntawm txhuas los yog tooj liab.
- Tom ntej no txheej - rwb thaiv tsev. Nws lub luag hauj lwm yog ua los ntawm daim ntawv, uas yog impregnated nrog ib tug tshwj xeeb cov neeg ua haujlwm, nws yog qhwv nyob rau hauv ob peb khaubncaws sab nraud povtseg.
- Tej zaum siv rwb thaiv tsev. Nyob rau hauv cov ntaub ntawv no, daim ntawv yog impregnated nestekayuschim, khov compound.
- kev tiv thaiv ntawm cov neeg ciaj thiab kev rho tawm yog ib tug raj ntawm cov hlau lead.
- Rau ntxiv dag zog rau thiab tiv thaiv tawm tsam xeb ntawm lub steel yeeb nkab siv Crepe ntawv nrog ib tug bitumen los yog ib tug polyethylene terephthalate fiber.
- Tom ntej no txheej - armor steel ib daim hlab.
- Xeem - txheej ua los ntawm bitumen los yog strands.
kev khiav hauj lwm tej yam kev mob
Thov cov khoom impregnated nrog ib tug khov khoom tsis nres dab tshos tsis tau txwv tsis pub rau kev tso kawm theem. Qhov txawv nruab nrab ntawm lawv yuav tsum tsis ntau tshaj 15 meters ntawm lub Upper thiab qis cov ntsiab lus. Yog hais tias nws yog cov uas tsis muaj voltage armored cov khoom los yog muaj ib daim tawv nqaij ntawm txhuas, nws yog ua tau los mus tiv thaiv qhov txawv yog tsis ntau tshaj li 25 meters.
Txawv tooj ntawm cores thiab tus ntoo khaub lig-seem ntawm ib tug cable ASB. Nyhav nws nyob rau cov ciaj ciam thiab ib txheej hauv lub cheeb. Qhov loj qhov seem thiab txoj kab uas hla, ntau dua qhov lub loj ntawm cov khoom.
txheej txheem ntawm kev tsim
Tus duab ntawm tus neeg xyuas pib nyob rau hauv lub seem. Yog hais tias qhov kev xaiv no yog mus txog 16 hli 2 rau tso tseg thiab tag nrho cov seem ntawm ib tug tub ntxhais, rau hauv daim ntawv nws tas puag ncig. Ua xws li ib tug kev tsim kho tso cai rau lub LRA parameter cable uas tsis muaj ntau tshaj li 50 mm 2.
Tus duab, muab faib mus rau hauv feem los yog cov nplais, yog yuav tsum tau rau conductors nrog ib tug ntoo khaub lig seem ntawm 25 hli 2 muaj rwb thaiv tsev duav. Compacted thaum lub sij hawm ntau lawm compulsorily xav tau cables ya thiab tso tseg conductors.
Ib leeg-wired nrog lub sector voos kheej-kheej ntawm curvature yog ua tsis tsawg tshaj li 0.5 hli 2.
Txwv tsis pub noj coincidence ntau tshaj 3 bands, uas yog superimposed on ib leeg, nrog rau cov rwb thaiv tsev ntawv CRS nrog ib tug voltage ntawm 6 kV. Yog hais tias peb yuav sib tham txog lub tapes, uas yog nyob ib sab mus rau lub leeg ncaj qha mus rau qhov kev tshuaj ntsuam, ces tus match tsis pub los ntawm ntau tshaj 2. Ib tug yuav xav tias coincidence txiav thiab folds tshaj 50m ob koj cov menyuam uas yog txheej txheem ib saum toj no rau lwm yam.
Finely CRS uas raug rho tawm ntsiab yog cov ntawv bundles, sau qhov chaw nruab nrab ntawm lawv. Leeg cais sector nyob rau hauv multicore cables, tsis tau cov tsis tau sau muaj ntau tshaj li 1kV.
Niaj hnub no, muaj ntau yam tuam txhab uas muag ua ASB cable. Nws nqi yuav nyob ntawm seb tsis tsuas yog los ntawm cov chaw tsim tshuaj paus, tab sis kuj los ntawm nws siv. Tus nqi ntawm ib tug nruab nrab ntawm 250 mus rau 800 rubles ib square meter.
Core npav
CRS cable uas nws specifications yog txawv npav muaj cov nram qab designations nyob rau hauv txawv hais ntawm nws siv. Cais conductors yuav tsum txawv coloring los yog tshwj xeeb xov tooj. Nyob rau tib lub sij hawm muab tso rau hauv lawv lub los yog tsis raug mus rau puas thiab yooj yim rau kev nyeem ntawv. Npav ua ribbons, txawv xim. Los tus xov tooj yog ua li cas siv ib tug tshwj xeeb embossing los yog los ntawm printing.
ASB cable. Seev suab nyob rau daim kab xev npav
Tus nqi ntawm 1 mus rau muab 4, txij thaum lub insulating nto los yog sawb uas nyob rau saum toj. Wherein txhua tooj raws li ib tug Hawj txawm, 4 - dub, 3 - liab, 2 - ntsuab los yog xiav, 1 - Dawb.
Nyob pes tsawg yog tsis ib txwm qhia, thiab nws cov xim tej zaum yuav txawv.
Tsis pub tsawg tshaj 3 meters teev ntaub ntawv, uas muaj cov lus qhia txog qhov kev tso tawm hnub tim thiab lub chaw tsim tshuaj paus. Kom ASB cable nrog ib lub cheeb ntau tshaj li 20 millimeters nyob rau hauv lub plhaub, siv ib tug xov ntawm cov xim txawv txawv. Cable sawb ua los ntawm daim ntawv nyob rau hauv tej yam ntuj tso xim.
Ua tus xaiv txoj kev yuav pab rau cov cable tshwj xeeb. Tsuas yog nws muaj peev xwm to taub ntau yam ntawm hom thiab lawv lub sij hawm. Tsis tas li ntawd, cov wizard yuav ua rau cov tsim nyog suav thiab lub adequacy ntawm cov ntaub ntawv uas txaus.
Yog li ntawd, peb pom seb zoo li cas lub ASB cable, thiab saib nws kev yam ntxwv.
