1. Intshayelelo
Xa kuziwa kwiintambo zombane, ukhuseleko kunye nokusebenza zizinto eziphambili eziphambili. Yiyo loo nto imimandla eyahlukeneyo ineenkqubo zayo zokuqinisekisa ukuba iintambo ziyahlangabezana nemigangatho efunekayo.
Ezimbini zezona nkqubo zaziwa kakhulu zezatifikethi ziI-UL (IiLebhu zababhali abangaphantsi)kwayeI-IEC (iKomishoni yezoMbane yeHlabathi).
- ULisetyenziswa ikakhulu kwiamantla Emelika(I-USA kunye neCanada) kwaye igxileukuthobela ukhuseleko.
- I-IECyiumgangatho wehlabathi(eqhelekileyo kwiIYurophu, iAsia kunye nezinye iimarike) eqinisekisa zombiniukusebenza kunye nokhuseleko.
Ukuba uumenzi, umthengisi, okanye umthengi, ukwazi umahluko phakathi kwale migangatho mibinikubalulekile ekukhetheni iintambo ezifanelekileyo kwiimarike ezahlukeneyo.
Masingene kwiiyantlukwano eziphambili phakathiImigangatho ye-UL kunye ne-IECkunye nendlela ezichaphazela ngayo uyilo lwentambo, isiqinisekiso, kunye nezicelo.
2. Umahluko ongundoqo phakathi kwe-UL ne-IEC
| Udidi | Umgangatho we-UL (kuMntla Melika) | Umgangatho we-IEC (kwihlabathi jikelele) |
|---|---|---|
| Ukhuseleko | Ikakhulu i-USA & Canada | Isetyenziswa kwihlabathi liphela (iYurophu, iAsia, njl. |
| Gxininisa | Ukhuseleko lomlilo, ukuqina, amandla omatshini | Ukusebenza, ukhuseleko, ukhuseleko lokusingqongileyo |
| Iimvavanyo zomlilo | I-VW-1, FT1, FT2, FT4 (Ukurhaxwa okungqongqo kwedangatye) | IEC 60332-1, IEC 60332-3 (Ukuhlelwa komlilo okwahlukileyo) |
| Amanqaku ombane | 300V, 600V, 1000V, njl. | 450/750V, 0.6/1kV, njl. |
| IiMfuneko zezinto eziphathekayo | Ukumelana nobushushu, ukunqanda umlilo | Umsi ophantsi, ukhetho lwe-halogen-free |
| Inkqubo yeSiqinisekiso | Ifuna uvavanyo lwelebhu ye-UL kunye noluhlu | Ifuna ukuthotyelwa kwe-IEC specs kodwa iyahluka ngokwamazwe |
Izinto eziphambili zokuThatha:
✅I-UL igxile ekukhuseleni nasekuchaseni umlilo, ngelixaI-IEC ilinganisa ukusebenza, ukusebenza kakuhle, kunye neenkxalabo zokusingqongileyo.
✅I-UL ineemvavanyo ezingqongqo zokutsha, kodwaI-IEC ixhasa uluhlu olubanzi lweentambo zomsi ophantsi kunye ne-halogen-free.
✅Ukuqinisekiswa kwe-UL kufuna imvume ethe ngqo, ngelixaUkuthotyelwa kwe-IEC kuyahluka ngokwemimiselo yendawo.
3. Iimodeli zeCable ze-UL kunye ne-IEC eziqhelekileyo kwi-Global Market
Iindidi ezahlukeneyo zeentambo zilandela imigangatho ye-UL okanye ye-IEC ngokuxhomekeke kuboisicelo kunye nemfuno yemarike.
| Isicelo | Umgangatho we-UL (kuMntla Melika) | Umgangatho we-IEC (kwihlabathi jikelele) |
|---|---|---|
| Iintambo zeSolar PV | UL 4703 | I-IEC H1Z2Z2-K (EN 50618) |
| IiCables zamandla oShishino | UL 1283, UL 1581 | IEC 60502-1 |
| Iingcingo zoKwakha | UL 83 (THHN/THWN) | IEC 60227, IEC 60502-1 |
| Iintambo zokuTshaja ze-EV | UL 62, UL 2251 | IEC 62196, IEC 62893 |
| Ulawulo & Iintambo zoMqondiso | UL 2464 | IEC 61158 |
