1. Isingeniso
Uma kukhulunywa ngezintambo zikagesi, ukuphepha kanye nokusebenza kuyizinto eziza kuqala. Kungakho izifunda ezahlukahlukene zinezinhlelo zazo zokuqinisekisa ukuqinisekisa ukuthi izintambo zihlangabezana namazinga adingekayo.
Izinhlelo ezimbili zezitifiketi ezaziwa kakhuluI-Ul (ama-laboratories angaphansi komhlaba)na-I-IEC (Ikhomishini Yezwe Lomhlaba Wonke).
- ULisetshenziswa ikakhulukazi ngaphakathii-America esenyakatho(I-USA neCanada) futhi igxileUkutholwa Kwezokuphepha.
- I-IECaImvelo Yomhlaba(evamile ngaphakathiI-Europe, e-Asia, nezinye izimakethe) lokho kuqinisekisa zombiliukusebenza nokuphepha.
Uma uyiUmkhiqizi, umphakeli, noma umthengi, ukwazi umehluko phakathi kwalezi zindinganiso ezimbilikubalulekile ekukhetheni izintambo ezifanele ezimakethe ezahlukahlukene.
Ake ungene omehluko osemqoka phakathiIzindinganiso ze-Ul ne-IECnokuthi zikuthinta kanjani ukwakheka kwamakhebula, isitifiketi, kanye nezicelo.
2. Umehluko obalulekile phakathi kwe-UL ne-IEC
| Uhlobo | Ul Standard (ENyakatho Melika) | I-IEC Standard (Global) |
|---|---|---|
| Ukuwahlangabezekayo | Ikakhulukazi i-USA neCanada | Kusetshenziswe Emhlabeni Wonke (Europe, Asia, njll.) |
| Gxila ekuqondeni | Ukuphepha komlilo, ukuqina, amandla omshini | Ukusebenza, ukuphepha, ukuvikelwa kwemvelo |
| Ukuhlolwa kwamalangabi | VW-1, FT1, FT2, FT4 (I-Flame Flame Retam) | IEC 60332-1, IEC 60332-3 (Ukuhlukaniswa komlilo okuhlukile) |
| Izilinganiso zeVoltage | I-300V, 600V, 1000V, njll. | 450 / 750v, 0.6 / 1KV, njll. |
| Izidingo Zezinto Ezibonakalayo | Ukuvimbela ukushisa, ilangabi-retardant | Intuthu ephansi, izinketho zamahhala zeHalogen |
| Inqubo yesitifiketi | Idinga ukuhlolwa kwelebhu ye-ul kanye nohlu | Kudinga ukuhambisana ne-IEC specs kepha kuyahluka ngezwe |
Ukuthathwa Key:
✅U-Ul ugxile ekuphepheni nasekumelaneni komlilo, ngenkathiUkusebenza kwezilinganiso ze-IEC, ukusebenza kahle, kanye nokukhathazeka kwemvelo.
✅I-Ul inokuhlolwa okuqinile kwezikhala, kodwaI-IEC isekela uhla olubanzi lwebheshe eliphansi le-ShoKE ne-halogen-free.
✅Isitifiketi se-Ul sidinga ukuvunywa okuqondile, ngenkathiI-IEC Ukuhambisana nokuhambisana nemithetho yendawo.
3. Amamodeli we-Ul kanye ne-IEC Cable amamodeli emakethe yomhlaba
Izinhlobo ezahlukene zezintambo zilandela amazinga we-ul noma we-IEC ngokuya ngeIsicelo sesicelo nemakethe.
| Isicelo | Ul Standard (ENyakatho Melika) | I-IEC Standard (Global) |
|---|---|---|
| Solar pv cables | UL 4703 | I-IEC H1Z2Z2-K (EN 50618) |
| Izintambo zamandla ezimboni | Ul 1283, ul 1581 | IEC 60502-1 |
| Ukwakha i-Wiring | UL 83 (Thhn / Thwn) | IEC 60227, IEC 60502-1 |
| Izintambo zokushaja ze-EV | Ul 62, ul 2251 | IEC 62196, IEC 62893 |
| Izintambo zokulawula nezimpawu zesiginali | Ul 2464 | IEC 61158 |
