1. Nhanganyaya
Kana zvasvika kune tambo dzemagetsi, kuchengetedza uye kuita ndizvo zvinonyanya kukosha. Ndosaka matunhu akasiyana aine masisitimu avo ekuona kuti tambo dzinosangana nezvinodiwa.
Maviri eanonyanyo zivikanwa certification masisitimu ariUL (Underwriters Laboratories)uyeIEC (International Electrotechnical Commission).
- ULinonyanya kushandiswa muNorth America(USA neCanada) uye inotarisakutevedzera kuchengeteka.
- IECari aglobal standard(common inEurope, Asia, uye mamwe misika) izvo zvinovimbisa zvesekushanda uye kuchengeteka.
Kana uri amugadziri, mutengesi, kana mutengi, kuziva misiyano pakati pezviyero zviviri izvi ndizvozvakakosha pakusarudza tambo dzakakodzera dzemisika dzakasiyana.
Ngatinyure mumisiyano yakakosha pakatiUL uye IEC zviyerouye mabatiro avanoita tambo dhizaini, certification, uye maapplication.
2. Misiyano Yakakosha Pakati peUL neIEC
| Category | UL Standard (North America) | IEC Standard (Global) |
|---|---|---|
| Coverage | Kunyanya USA & Canada | Inoshandiswa pasi rese (Europe, Asia, etc.) |
| Focus | Kuchengetedzeka kwemoto, kusimba, simba remagetsi | Kuita, kuchengetedza, kuchengetedza kwezvakatipoteredza |
| Flame Miedzo | VW-1, FT1, FT2, FT4 (Strict flame retadancy) | IEC 60332-1, IEC 60332-3 (yakasiyana moto kupatsanurwa) |
| Voltage Ratings | 300V, 600V, 1000V, nezvimwewo. | 450/750V, 0.6/1kV, nezvimwewo. |
| Zvinhu Zvinodiwa | Inodzivirira kupisa, inodzivirira moto | Yakaderera-utsi, halogen-isina sarudzo |
| Certification process | Inoda UL yekuongorora lab uye kunyorwa | Inoda kutevedzwa neIEC specs asi inosiyana nenyika |
Zvinokosha Zvokutora:
✅UL yakatarisana nekuchengetedza uye kudzivirira moto, apoIEC inoenzanisa mashandiro, kugona, uye kunetsa kwezvakatipoteredza.
✅UL ine bvunzo dzakasimba dzekupisa,asiIEC inotsigira huwandu hwakakura hwehutsi-hutsi uye halogen-isina tambo.
✅UL certification inoda mvumo yakananga, apoKutevedzwa kweIEC kunosiyana nemitemo yemuno.
3. Common UL uye IEC Cable Models muGlobal Market
Mhando dzakasiyana dzetambo dzinotevera UL kana IEC zviyero zvinoenderana neavokushandiswa uye kudiwa kwemusika.
| Application | UL Standard (North America) | IEC Standard (Global) |
|---|---|---|
| Solar PV Cables | UL 4703 | IEC H1Z2Z2-K (EN 50618) |
| Industrial Power Cables | UL 1283, UL 1581 | IEC 60502-1 |
| Kuvaka Wiring | UL 83 (THHN/THWN) | IEC 60227, IEC 60502-1 |
