Dab tsi yog BVR Cable Thiab BV Cable?

Bvr xov hlau thiab rvv cables yog tag nrho cov tub ntxhais cables nrog kev yooj yim. Qhov txawv ntawm bvr thiab rvv yog dab tsi?

Ib: dab tsi yog bvr hlau

Bvr hlau yog ib hom tshwj xeeb ntawm cov xaim hloov tau yooj yim rau lub thawv xa khoom, tseem hu ua cov xaim thib ob. Siv cov insulating txheej mos hlau ntawm lub cable tooj liab hlau polybutadiene, uas yog siv los kho cov hlua ruaj ruaj thiab qhia qhov chaw mos. Los ntawm feem ntau ntawm welders thiab architectural kho kom zoo nkauj tsim cov neeg ua haujlwm nyiam.

Ob: dab tsi yog rvv cable

Lub npe tag nrho ntawm rvv kab yog cable tooj liab hlau PVC insulated saj zawg zog xaim, alias sheathed hlau, hluav taws xob xaim, fais fab hlau, multi-core hlau, thiab lwm yam. Muaj feem xyuam rau cov xov tooj ntawm tes nteg mos qhov chaw nrog ntsuas AC tam sim no ntawm 300/500V thiab hauv qab no, siv rau lub hwj chim plugs, tswj cov kab thiab cov ntaub ntawv teeb liab coaxial cables ntawm cov khoom siv hauv tsev, cov cuab yeej siv hluav taws xob thiab cov khoom siv hluav taws xob thiab cov khoom siv automation. Anti-tub sab tub nyiag tswb system thiab lub tsev intercom system haum rau tej lub sijhawm.

Peb: qhov sib txawv ntawm bvr hlau thiab rvv cable

1. Qhov txawv ntawm cov ntawv Askiv

rvv: r stands rau tooj liab hlau, v stands rau insulating txheej polybutadiene

bvr: b yog ntaub hlau, v yog polyethylene, r yog mos

2. Ua haujlwm voltage sib txawv

rvv: ntsuas cable 300V / 500V

bvr: Qhov ntsuas hluav taws xob yog 450 / 750V, lub cable yog tsau rau 1 teev, thiab nws tuaj yeem tiv taus qhov ntsuas ntawm AC 50Hz, 2500V (450 / 750V), thiab 2000V ua haujlwm tus qauv voltage rau 5 feeb yam tsis tau hla.

3. Ua haujlwm kub sib txawv

rvv cable: rho tawm 10 degree rau ntxiv 70 degree.

Bvr hlau: qhov kub ua hauj lwm yuav tsum tsis txhob ntau tshaj 70 degree, qhov kub thiab txias ua hauj lwm ntawm BVR-105 hom yog 105 degree, thiab qhov kub ntawm cov hlau tso ib puag ncig yuav tsum tsis txhob tsawg tshaj li 0 degree.

4. Qhov sib txawv ntawm daim ntawv thov

rvv cable: haum rau lub hwj chim plugs, tswj cov kab thiab cov ntaub ntawv teeb liab coaxial cables rau cov khoom siv hauv tsev, cov twj paj nruag, cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob, thiab yog qhov tsim nyog rau kev tiv thaiv tub sab tub nyiag, lub tsev intercom systems, thiab lwm yam. cov chaw xws li cov khoom siv hauv tsev nruab nrab thiab lub teeb txawb, cov cuab yeej ntsuas, cov khoom siv hluav taws xob, thiab cov teeb pom kev zoo. Nws tuaj yeem xa cov ntaub ntawv tswj cov teeb liab thiab hloov cov ntaub ntawv hluav taws xob, thiab tseem tsim nyog rau kev tso rau hauv cov tais cable thiab cov yas hoses.

bvr hlau: tshwj xeeb saj zawg zog cable rau lub hwj chim faib txee yog siv los kho qhov hloov tau yooj yim tshaj plaws nyob rau hauv cov kab taag. Nws yog qhov tsim nyog rau kev sib txuas lus nrog kev tsav tsheb ntawm AC rated voltage ntawm 450/750V thiab hauv qab no, txhua hnub cov khoom siv hluav taws xob muaj zog, cov cuab yeej ntsuas, cov khoom siv sib txuas lus, thiab lwm yam. Nws yog tsim rau ntau yam khoom siv tshuab thiab muaj kev sib koom tes muaj zog.
