Kodi pali kusiyana kotani pakati pa Thhn ndi PV waya?

Waya wa THHN (Thermoplastic High Heat-resistant nayiloni) ndiPV (Photovoltaic) wayandi mitundu yonse ya zingwe zamagetsi, koma adapangidwira ntchito zosiyanasiyana ndipo ali ndi mawonekedwe osiyana:

Ntchito:

Waya wa THHN: Waya wa THHN nthawi zambiri amagwiritsidwa ntchito popanga mawaya amkati, monga nyumba zogona komanso zamalonda. Ndi yoyenera kulumikiza mawaya anthawi zonse m'malo owuma kapena achinyezi, kuphatikiza ngalande ndi ma tray a chingwe.

Waya wa PV: Waya wa PV, womwe umadziwikanso kutichingwe cha dzuwa, idapangidwa makamaka kuti igwiritsidwe ntchito pamakina amagetsi a photovoltaic, monga kukhazikitsa ma solar panel. Amagwiritsidwa ntchito kulumikiza mapanelo adzuwa ndi ma inverters, mabokosi ophatikizira, ndi zigawo zina zamakina amagetsi adzuwa.

Zomangamanga:

Waya wa THHN: Waya wa THHN nthawi zambiri amakhala ndi ma conductor amkuwa okhala ndi PVC (Polyvinyl Chloride) insulation ndi zokutira nayiloni kuti awonjezere chitetezo ndi kulimba. Imapezeka mumitundu yosiyanasiyana ya ma conductor ndi makulidwe a insulation.

Waya wa PV: Waya wa PV amapangidwa pogwiritsa ntchito zida zomwe sizingagwirizane ndi cheza cha UV, kutentha kwambiri, komanso malo akunja. Nthawi zambiri imakhala ndi ma conductor amkuwa okhala ndi zotchingira za polyethylene (XLPE) zomangika ndi jekete yapadera yosamva UV. Waya wa PV umapezeka mu makulidwe ake ndi masinthidwe kuti akwaniritse zofunikira zamakina amagetsi adzuwa.

Mawerengero a Kutentha ndi Malo:

Waya wa THHN: Waya wa THHN adavotera kuti agwiritsidwe ntchito potentha mpaka 90°C (194°F) m’malo owuma komanso mpaka 75°C (167°F) pamalo amvula. Sanapangidwe kuti aziwonekera panja kapena padzuwa.

Waya wa PV: Waya wa PV adapangidwa mwapadera kuti azitha kupirira kunja, kuphatikiza kutenthedwa ndi dzuwa, mvula, chipale chofewa komanso kutentha kwambiri. Imavoteledwa kuti igwiritsidwe ntchito pa kutentha kuyambira -40 ° C (-40 ° F) mpaka 90 ° C (194 ° F) ndipo imakhala yolimbana ndi UV kuti isawonongeke chifukwa cha kuwala kwa dzuwa.

Zitsimikizo ndi Miyezo:

Onse THHN waya ndiPV wayaangafunike kukwaniritsa ziphaso ndi milingo kutengera ntchito ndi ulamuliro. Waya wa PV nthawi zambiri umafunika kutsatira miyezo yamakampani monga UL 4703 ya zingwe zoyendera dzuwa.
