Lub zog tshiab huv si, xws li photovoltaic thiab cua zog, tab tom nrhiav tom qab thoob ntiaj teb vim nws cov nqi qis thiab ntsuab. Nyob rau hauv tus txheej txheem ntawm PV fais fab chaw nres tsheb Cheebtsam, tshwj xeeb PV cables yuav tsum tau mus cuag PV Cheebtsam. Tom qab xyoo ntawm txoj kev loj hlob, lub khw muag khoom hluav taws xob photovoltaic hauv tsev tau ua tiav rau ntau dua 40% ntawm lub ntiaj teb photovoltaic zog tsim. Yog li dab tsi hom PV kab feem ntau siv? Xiaobian ua tib zoo txheeb xyuas cov qauv PV cable tam sim no thiab cov qauv siv thoob ntiaj teb.
Ua ntej, European lag luam yuav tsum dhau TUV ntawv pov thawj. Nws tus qauv yog pv1-f. Qhov tshwj xeeb ntawm cov kab no feem ntau yog nruab nrab ntawm 1.5 thiab 35 mm2. Tsis tas li ntawd, qhov hloov kho dua tshiab ntawm tus qauv h1z2z2 tuaj yeem muab cov hluav taws xob muaj zog dua. Qhov thib ob, Asmeskas kev lag luam yuav tsum dhau UL daim ntawv pov thawj. Lub npe lus Askiv tag nrho ntawm daim ntawv pov thawj no yog ulcable. Cov specifications ntawm photovoltaic cables dhau UL ntawv pov thawj yog feem ntau nyob rau hauv qhov ntau ntawm 18-2awg.
Lub hom phiaj yog xa mus rau tam sim no. Qhov txawv yog qhov yuav tsum tau ua rau kev siv ib puag ncig sib txawv thaum xa cov khoom siv tam sim no, yog li cov ntaub ntawv thiab cov txheej txheem uas ua rau cov cable sib txawv.
Cov qauv photovoltaic cable: PV1-F, H1Z2Z2-K, 62930IEC131, thiab lwm yam.
Cov qauv siv ntau hom: RV, BV, BVR, YJV, VV thiab lwm cov tub ntxhais cables.
Qhov sib txawv ntawm cov kev xav tau siv:
1. Sib txawv ntsuas voltages
PV cable: 600/100V lossis 1000/1500V ntawm tus qauv tshiab.
Ordinary cable: 300/500V lossis 450/750V lossis 600/1000V (YJV / VV series).
2. Txawv adaptability rau ib puag ncig
Photovoltaic cable: Nws yuav tsum tau tiv taus kub, txias, roj, kua qaub, alkali, nag, ultraviolet, nplaim retardant thiab ib puag ncig tiv thaiv. Nws tuaj yeem siv rau hauv kev nyab xeeb hnyav nrog lub neej ua haujlwm ntawm ntau tshaj 25 xyoo.
Ordinary cable: feem ntau yog siv rau sab hauv tsev nteg, underground yeeb nkab tso thiab cov khoom siv hluav taws xob sib txuas, nws muaj qee yam kub thiab roj tsis kam, tab sis tsis tuaj yeem raug tawm sab nraum zoov lossis hauv qhov chaw hnyav. Nws lub neej kev pabcuam feem ntau yog nyob ntawm qhov xwm txheej tiag tiag, tsis muaj qhov tshwj xeeb.
Qhov sib txawv ntawm cov khoom siv raw thiab kev siv tshuab
1. Cov khoom sib txawv
PV kab:
Conductor: tinned tooj liab hlau conductor.
Rwb thaiv tsev: cross-linked polyolefin rwb thaiv tsev.
Jacket: cross-linked polyolefin rwb thaiv tsev.
Common kab:
Conductor: tooj liab conductor.
Rwb thaiv tsev: PVC los yog polyethylene rwb thaiv tsev.
Khoom siv: PVC sheath.
2. Cov txheej txheem sib txawv
Photovoltaic cable: cov tawv nqaij sab nrauv tau sib txuas thiab irradiated.
Cov kab hluav taws xob zoo ib yam: feem ntau tsis dhau kev sib txuas hluav taws xob, thiab YJV YJY series fais fab cables yuav raug sib txuas.
3. Cov ntawv pov thawj sib txawv
PV cables feem ntau xav tau TUV daim ntawv pov thawj, thaum cov kab hluav taws xob zoo ib txwm xav tau CCC daim ntawv pov thawj lossis tsuas yog daim ntawv tso cai tsim khoom.
