Lub hom phiaj ntawm Halogen Free Cable yog dab tsi?

Lub hom phiaj ntawm Halogen Free Cable yog dab tsi?

1, Bv kab tau muab faib ua 5 hom, uas yog dav dav, nplaim hluav taws, hluav taws-pov thawj, tsis muaj pa taws halogen-dawb, tsis muaj pa taws halogen-tsis muaj hluav taws pov thawj.

Zc-bv nplaim retardant tooj liab tub ntxhais hlau, tseem hu ua PVC insulated tsis sheathed nplaim retardant hlau thiab cable.

N-bv fireproof tooj liab tub ntxhais hlau, tseem hu ua PVC insulated tsis sheathed hluav taws-resistant hlau thiab cable.

Wdzc-byj tsawg pa luam yeeb halogen-dawb tooj liab tub ntxhais hlau, tseem hu ua halogen-dawb tsis muaj pa taws retardant chemical crosslinked isoprene roj hmab cable thiab hlau tsis muaj kev tiv thaiv sheath.

Wdzn-byj tsis tshua muaj pa taws halogen-tsis muaj hluav taws kub-pov thawj tooj liab tub ntxhais hlau, tseem hu ua halogen-dawb tsis muaj pa taws hluav taws-retardant tshuaj crosslinked isoprene roj hmab cable thiab xaim tsis muaj kev tiv thaiv sheath.

2, Scope ntawm kev siv

Nplaim hluav taws kub, hluav taws-pov thawj, tsis muaj pa taws halogen-dawb, tsis muaj pa taws halogen-dawb hluav taws-pov thawj tooj liab tub ntxhais hlau. Cov pa taws teeb meem tshwm sim los ntawm qhov hluav taws kub ntawm cov khoom siv raw ntawm cov rwb thaiv tsev thiab cov txheej txheem tiv thaiv hauv cov nplaim hluav taws yog qis dua tus nqi teev tseg. Nws yog tsuas yog siv nyob rau hauv ntau-storey tsev, loj khw malls, tshuaj nroj tsuag, coj mus muag squares thiab lwm yam kev siv pej xeem siv nrog AC rated tam sim no ntawm 450/750v thiab hauv qab no, raws li zoo raws li cov chaw uas muaj zog cov kev cai ntawm cov nplaim-retardant yam ntxwv ntawm cables.

3, Cov yam ntxwv ntawm kev siv

1. Qhov ntsuas kub ntawm lub cable yuav tsum tsis txhob tsawg dua 0 degree

2. Lub sij hawm ntev tso cai kub ntawm PVC insulated cable yuav tsum tsis txhob ntau tshaj 70 degree, thiab lub sij hawm ntev tso cai ua hauj lwm kub ntawm tshuaj crosslinked isoprene roj hmab insulated hlau yuav tsum tsis txhob ntau tshaj 105 degree.

3. Qhov kev tso cai khoov lub vojvoog ntawm cable nrog txoj kab uas hla D tsawg dua 25 hli yuav tsum tsis pub tsawg dua 4D. Qhov kev tso cai khoov lub vojvoog ntawm cable nrog txoj kab uas hla D ntawm 25mm thiab cov kab saum toj no yuav tsum tsis pub tsawg dua 6dzc-bv thiab nh-bv.

Zc-bv: cable tooj liab hlau PVC insulated nplaim retardant cable: insulating khoom ntxiv halogen-dawb nplaim retardant, tawm hauv hluav taws tsis muaj hluav taws. nplaim retardant bv xaim muab faib ua peb theem: A, B, C, thiab chav A yog zoo dua, thiab lwm yam;

N-bv: cable tooj liab hlau PVC insulated hluav taws-resistant hlau: muaj ib tug insulating txheej ntawm hluav taws-resistant rwb thaiv tsev khoom ntawm PVC insulating txheej thiab tooj liab conductor. Txawm hais tias cov yas txheej txheej insulating yog kub hnyiab, kuj tseem muaj cov txheej txheem hluav taws kub, uas yuav tsis ua rau lub sijhawm luv luv. Thaum xaim, txiav cov txheej txheem hluav taws kub ntawm qhov sib txuas. Yog tias nws tsis raug txiav, txoj kev tsis yog conductive los ntawm txheej insulating. Nws tuaj yeem siv tau raws li qhov chaw ntawm qhov hluav taws kub ib txwm muaj.
