Yintoni umahluko phakathi kweThn kunye nePV wire?

I-THHN (i-Thermoplastic High-Heat-resistant Nylon-coated) ucingo kunyeI-PV (Photovoltaic) ucingozombini iindidi zeentambo zombane, kodwa ziyilelwe usetyenziso olwahlukileyo kwaye zineempawu ezahlukileyo:

Isicelo:

Ucingo lwe-THHN: Ucingo lwe-THHN luqhele ukusetyenziswa kwizicelo zocingo zangaphakathi, njengezakhiwo zokuhlala kunye nezorhwebo. Ifanelekile kwi-wiring yenjongo ngokubanzi kwiindawo ezomileyo okanye ezifumileyo, kuquka i-conduit kunye neetreyi zekhebula.

I-PV wire: I-PV wire, eyaziwa ngokubaintambo yelanga, yenzelwe ngokukodwa ukusetyenziswa kwiinkqubo zamandla e-photovoltaic, ezifana nokufakelwa kweepaneli zelanga. Isetyenziselwa ukudibanisa iipaneli zelanga kwii-inverters, iibhokisi zokudibanisa, kunye namanye amacandelo eenkqubo zamandla elanga.

Ulwakhiwo:

Ucingo lwe-THHN: Ucingo lwe-THHN ludla ngokuqulatha iikhondaktha zobhedu ezine-PVC (i-Polyvinyl Chloride) yokugquma kunye nokwaleka kwenayiloni ukongezelela ukhuseleko kunye nokuqina. Ifumaneka kwiisayizi ezahlukeneyo ze-conductor kunye nobukhulu be-insulation.

Ucingo lwePV: Ucingo lwePV lwakhiwa kusetyenziswa izinto ezikwaziyo ukumelana nemitha yeUV, ubushushu obugqithisileyo, kunye nemekobume yangaphandle. Ngokuqhelekileyo inezikhondaktha zobhedu ezinkonkxiweyo ezine-polyethylene edibeneyo (XLPE) insulation kunye nejacket ekhethekileyo ye-UV-resistant. I-PV wire ifumaneka ngobukhulu obuthile kunye nolungelelwaniso ukuhlangabezana neemfuno zeenkqubo zamandla elanga.

Amazinga obushushu kunye nokusiNgqongileyo:

Ucingo lwe-THHN: Ucingo lwe-THHN lulinganiswe ukuba lusetyenziswe kumaqondo obushushu ukuya kuma-90°C (194°F) kwiindawo ezomileyo kunye nokuya kutsho kuma-75°C (167°F) kwiindawo ezimanzi. Ayenzelwanga ukuvela ngaphandle okanye ngokuthe ngqo kukukhanya kwelanga.

Ucingo lwe-PV: Ucingo lwe-PV lwenziwe ngokukodwa ukuba lukwazi ukumelana neemeko zangaphandle, kuquka ukuchanabeka elangeni, imvula, ikhephu, namaqondo obushushu agqithisileyo. Ilinganiswe ukuba isetyenziswe kumaqondo obushushu ukusuka ku -40°C (-40°F) ukuya kuma-90°C (194°F) kwaye ayinyangeki kwi-UV ukunqanda ukuthotywa kokukhanya kwelanga.

Iziqinisekiso kunye neMigangatho:

Zombini ucingo lwe-THHN kunyeucingo lwePVkunokufuna ukuhlangabezana neziqinisekiso ezithile kunye nemigangatho ngokuxhomekeke kwisicelo kunye negunya. Ucingo lwe-PV luhlala lufuneka ukuba luhambelane nemigangatho yoshishino efana ne-UL 4703 yeentambo zelanga.
