Main feature
1. Txee qauv yog hom sib dhos, lub Circuit Court breaker adopts pem teb hom handcart qauv;
2. Nruab nrog cov khoom tshiab sib xyaw insulated lub tshuab nqus tsev Circuit Court breaker, yog featured nrog zoo interchangeability, thiab yog yooj yim los hloov;
3. Lub tshuab nqa tes yog mounted nrog txhuas ntsia hlau ntsia hlau propelling mechanism, nws muaj peev xwm txav tau lub laub tau yooj yim, thiab tiv thaiv kev puas tsuaj ntawm lub tshuab txav los ntawm kev ua haujlwm tsis zoo;
4. Txhua txoj haujlwm tuaj yeem ua tiav thaum lub qhov rooj kaw;
5. Interlocking ntawm lub ntsiab hloov, handcart thiab switchgear txais yuav tsum mechanical locking hom, ntsib lub "tsib tiv thaiv" muaj nuj nqi;
6. Cable chamber loj txaus, nws tuaj yeem txuas ntau cables;
7. Lub ntiaj teb ceev ceev hloov yog siv rau earthing thiab circuit short-circuit;
8. Qib kev tiv thaiv ntawm qhov thaiv yog IP3X, thiab yog IP2X thaum qhib lub qhov rooj ntawm lub qhov rooj;
9. Cov khoom ua raws li GB3906-1991, DL404-1997 thiab hais txog tus txheej txheem thoob ntiaj teb IEC-298.
Siv tej yam kev mob
1. Ambient kub: -10 ℃ ～ + 40 ℃, tus nqi ntsuas ntsuas hauv 24h yuav tsum tsis pub tshaj 35C.
2. Qhov siab: tsis tshaj 3000m;
3. Tus txheeb ze av noo: ib hnub txhais tau tias tsis tshaj 95%, txhua hli txhais tsis tshaj 90%;
4. Seismic siv: tsis tshaj Ms8;
5. Vapor siab: txhua hnub txhais tau tias tsis tshaj 2.2kPa, txhua hli txhais tsis tshaj 1.8kPa.
6. Ib puag ncig puag ncig: qhov chaw teeb tsa yuav tsum tsis muaj hluav taws kub, muaj kev phom sij tawg, muaj kuab paug loj, tshuaj lom neeg corrosion lossis kev co hnyav.
