I-IEC BS iMigangatho ye-12-20kV-XLPE efakwe i-PVC egqunywe ngentambo yombane yeMV

Iinkcukacha:

    Ilungele uthungelwano lwamandla olufana nezikhululo zamandla.Ukufakwa kwimibhobho, phantsi komhlaba nangaphandle.

    Kukho iiyantlukwano ezinkulu kulwakhiwo, imigangatho kunye nezinto ezisetyenzisiweyo - ukucacisa intambo yeMV echanekileyo yeprojekthi ngumbandela wokulinganisa iimfuno zokusebenza, iimfuno zofakelo, kunye nemingeni yokusingqongileyo, kwaye emva koko kuqinisekiswe ukuthotyelwa kwentambo, ishishini, kunye nolawulo.NgeKomishoni yoBuchwephesha boMbane baMazwe ngaMazwe (IEC) ichaza iintambo zombane oPhakathi njengezinomlinganiselo wamandla ombane angaphezu kwe-1kV ukuya kutsho kwi-100kV leyo luluhlu olubanzi lwamandla ombane ekufuneka luqwalaselwe.Kuxhaphake kakhulu ukucinga njengoko sisenza malunga ne-3.3kV ukuya kwi-35kV, phambi kokuba ibe ngamandla ombane aphezulu.Sinokuxhasa ukucaciswa kwentambo kuzo zonke ii-voltages.

Iithegi zeMveliso

Isicelo :

Ilungele uthungelwano lwamandla olufana nezikhululo zamandla.Ukufakwa kwimibhobho, phantsi komhlaba nangaphandle.Nceda uqaphele: I-sheath yangaphandle ebomvu inokufiphala xa ibekwe kwimitha ye-UV.

Imigangatho:

Ukusasazwa komlilo kwi-BS EN60332
BS6622
IEC 60502

Iimpawu :

I-Conductor: Iikhonduki zobhedu ezixineneyo ezityaliweyo okanyeumqhubi we-aluminium

Isingxobo: Isingxobo sePVC sangaphandle
Umbala weSheath: Obomvu okanye Mnyama

Idatha yoMbane:

Elona qondo lobushushu lisebenza ngumqhubi: 90°C
Obona bushushu bokusebenza kwesikrini: 80°C
Elona qondo liphezulu lobushushu be-conductor ngexesha le-SC: 250°C
Iimeko zokubeka kwindawo yokwakhiwa kwe-trefoil yile ilandelayo:
Ukumelana nobushushu bomhlaba: 120˚C.Cm/Watt
Ubunzulu bokungcwaba: 0.5m
Ubushushu bomhlaba: 15°C
Ubushushu bomoya: 25°C
Ukuphindaphinda: 50Hz

Undoqo omnye 12/20 kV
