Uyini umehluko phakathi kwe-Thn ne-PV wire?

I-THHN (i-Thermoplastic High Heat-resistant Nylon-coated) ngocingo kanyeIntambo ye-PV (Photovoltaic).zombili izinhlobo zezintambo zikagesi, kodwa zenzelwe izinhlelo zokusebenza ezahlukene futhi zinezici ezihlukile:

Isicelo:

Intambo ye-THHN: Intambo ye-THHN ivame ukusetshenziswa ezinhlelweni zokufaka izintambo zasendlini, njengezakhiwo zokuhlala nezohwebo. Ilungele izintambo ezijwayelekile ezindaweni ezomile noma eziswakeme, okuhlanganisa imisele kanye namathreyi ekhebula.

Intambo ye-PV: Intambo ye-PV, eyaziwa nangokuthiikhebula lelanga, yakhelwe ngokukhethekile ukusetshenziswa ezinhlelweni zamandla e-photovoltaic, njengokufakwa kwamaphaneli elanga. Isetshenziselwa ukuxhuma amaphaneli elanga kuma-inverters, amabhokisi okuhlanganisa, nezinye izingxenye zezinhlelo zamandla elanga.

Ukwakha:

Intambo ye-THHN: Intambo ye-THHN ngokuvamile iqukethe amakhondatha ethusi ane-PVC (Polyvinyl Chloride) insulation kanye nenayiloni enamathelayo ukuze kuvikeleke okwengeziwe nokuhlala isikhathi eside. Itholakala ngamasayizi ahlukahlukene we-conductor kanye nokuqina kwe-insulation.

Intambo ye-PV: Intambo ye-PV yakhiwa kusetshenziswa izinto ezimelana nemisebe ye-UV, amazinga okushisa aphakeme, kanye nezindawo ezingaphandle. Ivamise ukufaka izikhondatha zethusi ezithayiwe ezine-polyethylene (XLPE) exhunywe ngokuphambanayo kanye nejazi elikhethekile elimelana ne-UV. Intambo ye-PV iyatholakala ngosayizi abathile kanye nokucushwa ukuze kuhlangatshezwane nezidingo zezinhlelo zamandla elanga.

Izilinganiso Zezinga lokushisa Nezemvelo:

Intambo ye-THHN: Intambo ye-THHN ilinganiselwe ukusetshenziswa emazingeni okushisa afika ku-90°C (194°F) ezindaweni ezomile futhi afika ku-75°C (167°F) ezindaweni ezimanzi. Ayakhelwe ukuchayeka ngaphandle noma elangeni.

Intambo ye-PV: Intambo ye-PV yakhelwe ngokukhethekile ukuthi imelane nezimo zangaphandle, okuhlanganisa ukuchayeka elangeni, imvula, iqhwa, namazinga okushisa aphezulu. Ikalelwe ukusetshenziswa emazingeni okushisa asuka ku -40°C (-40°F) kuya ku-90°C (194°F) futhi ayimelani ne-UV ukuze ivimbele ukucekelwa phansi kokuchayeka elangeni.

Izitifiketi Namazinga:

Kokubili i-THHN wire kanyeIntambo ye-PVingase idinge ukuhlangabezana nezitifiketi ezithile namazinga kuye ngohlelo lokusebenza namandla. Intambo ye-PV ivamise ukudingeka ukuze ihambisane namazinga omkhakha afana ne-UL 4703 yamakhebuli elanga.
