Dab Tsi Yog Qhov Rwb Thaiv Hlau?

Cov ntawv hu ua insulated hlau yog cov khoom siv tsis yog-cov rwb thaiv tsev qhwv ib puag ncig sab nraud ntawm cov xov hlau xaim xov hlau, feem ntau, qhov khoom siv no zoo tshaj qhov nruab nrab lub xov hlau rwb thaiv tsev zoo dua. Nyob rau sab nraud ntawm cov hlau yog tusyees thiab muab khi ua ke los qhwv ib txheej ntawm cov ntaub ntawv tsis muaj khoom, xws li: resin, yas, roj hmab silicone, PVC, thiab lwm yam, los ua ib qho txheej insulating, los tiv thaiv lub cev conductive los ntawm kev sib cuag nrog lub ntiaj teb sab nraud los ntawm xau, luv luv Circuit Court, hluav taws xob sib tsoo thiab lwm yam kev sib tsoo ntawm cov hlau hu ua insulated hlau.

Hauv Suav teb, tuaj yeem siv ua cov hlau tsis muaj cov khoom ua txhaum, yas, cov khoom siv pvc, silicone roj hmab, thiab lwm yam, cov ntaub ntawv no mus rau hauv cov hlau rwb thaiv tsev txheej, tuaj yeem tiv thaiv tus neeg xyuas pib thiab sab nraud kev sib cuag, thiaj li kom tsis txhob xau hlau, luv Circuit Court thiab lwm yam.

Tsis tas li ntawd, nyob rau hauv cov nqe lus ntawm kev siv, rwb thaiv tsev hlau daim ntaub ntawv yog qhov dav heev. Feem ntau ntawm cov xov hlau uas peb siv hauv tsev yog cov kab hluav taws xob hauv kab hluav taws xob, thiab muaj ntau yam txheej txheem kev tsim kho loj, khoom siv hluav taws xob, hluav taws xob engineering, thiab lwm yam.

Cov qauv ntawm cov kab hlau insulated tseem cuam tshuam txog kev siv, thiab cov tsiaj ntawv sib txawv sawv cev tsis tsuas yog cov qauv sib txawv, tab sis kuj siv sib txawv. R, piv txwv, sawv cev hlau tooj liab muag, S sawv cev rau khub sib kis, thiab P sawv cev rau cov kab thaiv kev tiv thaiv.

Kev Siv Qauv

R sawv rau cov hlau tooj liab muag muag, V sawv rau PVC rwb thaiv tsev, S sawv rau kev sib ntswg, B sawv cev rau hom tiaj tus, Thiab P sawv cev tiv thaiv.

1. RV - PVC insulated ib leeg tub ntxhais txoj hlua, kev siv hluav taws xob ntau tshaj yog 65 degrees C, qhov siv kub tshaj plaws ntawm -15 degrees C, kev khiav hauj lwm voltage AC 250V, DC 500V, siv raws li cov xaim hluav taws xob sab hauv ntawm cov twj paj nruag thiab khoom siv.

2. RVB: mus tib seem ntau hom kab hlau mos (tiaj tus), ib yam li lub tsev feem ntau siv xov tooj kab kab, tab sis cov tub ntxhais kab thiab RVV cov tub ntxhais kab xwm yeem, ob txoj kev ua txhaum sinnuse yog mus tib seem, feem ntau yog ib sheath ob

3. RVS: ntawm winch multi-stranded soft line, yog RVB mos core kom tawm qhib, tom qab winch tuaj yeem. Feem ntau ob khub ntawm strands.

4. RVSP: twisted khub thaiv npog hlau.

5. RVVB: PVC sheath cov hlau mos (hom loj), qauv GB / T 5023.5-2008 / IEC 60227-5: 2003.

6. RVV: ntau-tso tseg cov hlau mos, yog cov tub ntxhais kab sib xyaw ua ke ntawm cov hlau ntau tooj liab, RVV hlau yog cov hluav taws xob tsis muaj zog yog cov feem ntau siv cable, nws cov tub ntxhais lub hauv paus tsis meej, muaj ib lub hauv paus, muaj ntau cov hauv paus hniav, muaj cov sheaths nyob sab nraud. Txawm li cas los xij, tsis muaj ib txoj cai tshwj xeeb rau kev npaj ua ntawm cov cores.

7. RVVP: tooj liab tub ntxhais PVC rwb thaiv tsev tiv thaiv PVC sheath mos cable, tseem hu ua hluav taws xob txuas txuas tiv thaiv jamming mos cable, ntsuas voltage 250V / 450V.

8. BVVR yog tooj liab tub ntxhais PVC insulated PVC sheath mos hlau, muaj cov tiv thaiv txheej sab nrauv; BVR yog tooj liab tub ntxhais PVC insulated mos hlau, tsuas yog txheej rwb thaiv tsev, tsis muaj txheej sab nraud. Feem ntau hais tias ob chav yas kab yog hais txog BVV series, thawj V yog hais txog PVC rwb thaiv tsev, tus thib ob V yog hais txog PVC sheath, yog tias BV series hais txog tib txoj kab yas.
