Dab tsi BVR xaim txhais tau tias BVR hlau xaim hluav taws xob qauv qauv qauv
BVR hlau txhais li cas? BVR yog tooj liab tub ntxhais PVC insulated hloov yooj ywm; Hauv qab no yog kev txhais cov ncauj lus kom ntxaws ntawm Kev Tshaj Tawm Rau Cov Xov Xwm Ntawm BVR, Kuv vam tias yuav pab koj!
BVR hlau yog ib hom hlau tshwj xeeb hloov tau rau cov txee xa khoom, tseem hu ua hlau theem nrab. Tooj liab tub ntxhais PVC insulated yooj ywm hlau yog siv rau cov xov txuas ruaj qhov twg softness yuav tsum. Los ntawm feem ntau ntawm cov khoom siv hluav taws xob thiab cov neeg ua haujlwm kho kom zoo nkauj nyiam.
BVR xaim
BVR txhais li cas
BV, BVV, BVVB, BVR Hwj Huaj Qaum:
Txhawm rau muab nws yooj yim: VV hauv cov ntsiab lus xaim txhais tau tias ob txheej ntawm dew ethylene;
BV polydew ethylene insulated tooj liab tub ntxhais hlau, cov ntxhais hlau loj;
BVV, lwg ethylene sheathed tooj liab tub ntxhais hlau, ob tug ntxhais hlau;
BVVB lwg ethylene sheathed tooj liab tseem ceeb, yog peb-ntxhais xaim;
BVR, tus neeg xyuas pib tooj liab PVC ntxig hlau tsis kam hloov pauv, xaim hluav taws xob thaum xav tau muag muag zaus.
Cov neeg nug cov hlau ib txwm nyob ntawm kev ua lag luam BV, BVR, RV, RVV, tsis yog cov ntu loj ntawm kev siv tshuab hluav taws xob
B series belongs rau cov hlau xa tawm, yog li nws pib nrog B, voltage: 300 / 500V;
V yog PVC, polyvinyl chloride, uas yog cov yas;
L yog kev cai rau cov tub ntxhais aluminium;
R txhais tau tias mos, thiab ua tus muag muag, koj nce tus naj npawb ntawm kev coj ua;
BV tooj liab neeg xyuas pib PVC insulated hlau;
BLV aluminium tub ntxhais PVC insulated hlau;
BVR tooj liab neeg xyuas pib PVC insulated hlau hloov tau.
Saum cov qauv hlau: neeg xyuas pib + rwb thaiv tsev.
Noj 2.5mm2 piv txwv:
Muaj ob hom BV: 1 lub hauv paus nrog txoj kab uas hla ntawm 1.78mm thiab 7 lub hauv paus nrog txoj kab uas hla ntawm 0.68.
BLV yog 1 lub hauv paus nrog txoj kab uas hla ntawm 1.78 hli; BVR yog 19 lub hauv paus nrog txoj kab uas hla ntawm 0.41mm.
RV tooj liab neeg xyuas pib PVC insulated hloov tau hlau nws yog softer dua BVR, los yog 2.5 yog 49 0.25 hli tooj liab xaim;
RV tooj liab neeg xyuas pib PVC insulated PVC sheathed saj zawg zog hlau muaj ib txheej ntxiv ntawm cov yas sheathed dua RV
Tsis tas li: Peb qhov&feem ntau siv; kab sheath"
BVVB tooj liab neeg xyuas pib PVC insulated PVC sheathed tiaj cable yog 2 BV hlau, ntxiv rau ib txheej txheej dawb txheej.
