BV Cable yog dab tsi?

Rau ntau lub tsev kho kom zoo nkauj cable cov neeg siv khoom, lawv tsis paub qhov txawv ntawm bv hlau thiab rv hlau. Cov hom cable no txawv ntawm txoj kev naming, qauv thiab Scope ntawm daim ntawv thov. Cia peb paub txog bv hlau thiab rv hlau:

BV: cable tooj liab hlau PVC insulated cable yog ib qho tseem ceeb ntawm tooj liab hlau. Nws tseem hu ua hard hlau vim nws nyuaj heev.

RV: cable tooj liab hlau PVC insulated txuas cov xaim hloov tau yooj yim yog tooj liab xaim, uas yog ib leeg tub ntxhais hlau nrog ntau cov tub ntxhais tooj liab xov hlau sib tw ua ke.

1, Qhov txawv ntawm bv hlau thiab rv hlau:

1: Bv xaim yog cov xaim tawv, uas yog siv dav hauv tsev kho kom zoo nkauj. rv hlau yog cov hlau mos, uas tsis tuaj yeem siv hauv tsev kho kom zoo nkauj.

2: Qhov ntsuas hluav taws xob sib txawv. Feem ntau, qhov ntsuas hluav taws xob ntawm BVR yog siab dua. RV yog 300/500V los yog 450/750V, thiab BV yog 300/500V los yog 450/750V.

3: Cov qauv siv cov khoom sib txawv. Cov qauv siv rau bv xov hlau yog GB/T5023-2008 thiab rv xov hlau yog GB/T5023.3-2008.

4: Daim ntawv thov qhov chaw sib txawv. bv yog tsuas yog siv nyob rau hauv cov electrode kev twb kev txuas kab ntawm lub tsev teeb pom kev zoo kab, thiab rv yog tsuas yog siv nyob rau hauv lub electrode kev twb kev txuas kab ntawm cov khoom siv hauv tsev.

5: Tus nqi ntawm rv hlau yuav siab dua li ntawm bv hlau.

6: Lub neej ua haujlwm txawv. Lub rv tooj liab hlau yog ib qho yooj yim rau oxidized los ntawm huab cua, yog li kev pab cuam lub neej ntawm bv nyuaj hlau ntawm cov kab sib kis tau muab tso rau ntawm lub rooj tsav xwm Circuit Court ntev yuav ntev dua li ntawm rv tooj liab hlau.

2, Zoo sib xws ntawm bv hlau thiab rv hlau:

BV xaim thiab rv xaim yog tag nrho cov ntaub ntawv ib leeg, thiab txheej rwb thaiv tsev yog ua los ntawm polyethylene. Lawv tsis muaj hlau sheath, thiab qhov ntsuas hluav taws xob yog 450/750V thiab 300/500V.

3, Dab tsi yog qhov zoo ntawm bv xaim piv nrog rv hlau:

1: Bv xaim yuav tsum muaj kev ua tau zoo dua, txawm tias nws yog kev xaim lossis xaim hluav taws xob. Tsis tas li ntawd, thaum ua cov khoom sib txuas lossis ua cov xaim ntawm cov khoom sib txuas, rv, raws li cov xaim tooj liab, feem ntau tsim cov burrs uas tsis raug txheeb xyuas, ua rau luv luv thiab xau.

2: Lub tensile kuj ntawm rv hlau yog zoo dua li ntawm rv hlau.

3: Lub rv hlau yog tsim los ntawm ntau cov tub ntxhais filaments, thiab cov resistor ntawm txhua txoj hlua yog loj heev. rv hlau yog ib qho hluav taws xob hluav taws xob, yog li nyob rau hauv tsev neeg hluav taws xob, lub cable tam sim no nqa lub peev xwm thiab kub tsis kam ntawm rv hlau yog ntau dua li cov rv hlau.

Bv xov hlau feem ntau siv tib lub zog hluav taws xob hluav taws xob hluav taws xob sheath cables, uas muaj feem xyuam rau cov cables thiab cov xov hlau uas feem ntau siv hauv cov chaw nres tsheb fais fab, cov khoom siv hluav taws xob, cov cuab yeej ntsuas thiab cov khoom sib txuas lus nrog AC tam sim no ntawm 450/750V thiab hauv qab no. RV cable yog dav siv nyob rau hauv kev lag luam tsim hluav taws xob khoom siv hluav taws xob kev lag luam, tshwj xeeb tshaj yog nyob rau hauv cov chaw sib dhos nruj, xws li cov khoom siv hluav taws xob, cov khoom siv hluav taws xob thiab ntau yam khoom siv hluav taws xob tsawg. Nws yog qhov tsim nyog rau kev xa cov ntaub ntawv teeb liab thiab hloov cov teeb liab ntawm hluav taws xob hluav taws xob engineering thiab hluav taws xob tswj qhov system.
