Cov ntawv ntawm Cable txhais li cas?

Cov tsiaj ntawv Askiv, qauv thiab specifications ntawm cables thiab xov hlau sawv cev li cas? Cov kab twg yog RVV? Cov kab twg yog RVB? Qhov chaw twg thiab ib puag ncig lawv feem ntau siv nyob rau hauv? Qhov no yog txhua yam hais txog kev paub txog cov cables thiab cov xov hlau. ua hauj lwm efficiency.

1. Lub ntsiab lus ntawm universal kev txheeb xyuas ntawm cables

(1) Tus lej: B-cable (qee zaum tsis tau teev tseg)

(2) Hluav taws xob cov neeg xyuas pib: T-tooj ​​liab core (feem ntau yog qhov chaw piav qhia), L-aluminium core, R-mos tooj liab

(3) Rwb thaiv tsev: V-polyethylene, X-eraser, F-neoprene eraser

(4) Hlau grommet: V-polyethylene

(5) Lwm tus: R yog qhov hloov tau yooj yim, P yog daim thaiv npog, thiab B yog lub dav hlau sib luag

2. Piv txwv ntawm cov khoom siv cables

(1) BV, BLV: polyethylene insulated cable. Tib yam li hom BX, tab sis nrog zoo noo noo thiab huab cua tsis kam.

(2) BVR: polyethylene insulating txheej hloov tau yooj yim cable. Ib yam li hom BV, tsuas yog siv nyob rau hauv qhov chaw uas yuav tsum tau softness thaum lub installation.

(3) BVV, BLVV: polyethylene rwb thaiv tsev thiab sheathed cables. Ib yam li BV hom, nws yog siv rau hauv qhov chaw uas muaj kev xav tau siab rau ntub thiab txias thiab cov cuab yeej siv kev nyab xeeb, thiab tuaj yeem raug faus ncaj qha rau hauv cov av txheej.

(4) BV-105, BLV-105: Kub tiv taus 105 degree polyneon butadiene insulated cable yog tib yam li hom B, siv nyob rau hauv qhov kub thiab txias ntawm 45 degree thiab siab dua.

(5) BVR-105: Kub resistant 105 degree polyethylene rwb thaiv tsev hloov tau yooj yim cable. Ib yam li BVR hom, siv nyob rau hauv qhov kub thiab txias ntawm 45 degree thiab siab dua.

(6) RV: ib leeg-core tooj liab tub ntxhais vinyl chloride insulating txheej insulating txheej tooj liab hlau. Nws yog siv rau kev xaim ntawm ntau yam khoom siv hauv tsev txawb, ntsuas vaj huam sib luag, cov khoom sib txuas lus, thiab cov cuab yeej siv tshuab automation; nws kuj yog siv los ua ib qho kev sib txuas sab hauv, thiab kev ua haujlwm kub thaum lub sijhawm teeb tsa yuav tsum tsis txhob tsawg dua -15 degree .

(7) RVB: Ob-core ca tooj liab-core polyethylene insulated tooj liab hlau. Nws yog siv rau kev xaim ntawm ntau yam khoom siv hauv tsev txawb, ntsuas vaj huam sib luag, cov khoom sib txuas lus, thiab cov cuab yeej siv tshuab automation; nws kuj yog siv los ua ib qho kev sib txuas sab hauv, thiab kev ua haujlwm kub thaum lub sijhawm teeb tsa yuav tsum tsis txhob tsawg dua -15 degree .

(8) RVS: Ob-core tooj liab-core polyethylene stranded tooj liab hlau. Nws yog siv rau kev xaim ntawm ntau yam khoom siv hauv tsev txawb, ntsuas vaj huam sib luag, cov khoom sib txuas lus, thiab cov cuab yeej siv tshuab automation; Nws kuj tseem siv tau los ua cov xaim hluav taws xob sab hauv, thiab kev ua haujlwm kub thaum lub sijhawm teeb tsa yuav tsum tsis pub tsawg dua 15 degree. Qhov chaw muaj kev xav tau siab thiab nquag txav thiab khoov.

(9) AVR; electroplated tin tooj liab tub ntxhais polyethylene rwb thaiv tsev txheej ca txuas tooj liab hlau.

(10) RV-105: tooj liab tub ntxhais kub kub resistant 1050C polyethylene rwb thaiv tsev txheej polyethylene rwb thaiv tsev txheej txuas tooj liab hlau.

3. Feem ntau hom thiab specification series ntawm fais fab kis kab yog tsim

(1) Compression tsis kam; 300/500V, 450/750V

(2) Specifications thiab qauv; 1.5, 2.5, 4, 6, 10, 16, 25, 32, 50, 70, 95, 120, 150, 185, 240, 300, 400.
