Model

Chimiro Chechimiro

1. Iyo arc-kudzimisa kamuri iri pachikamu chepamusoro uye iyo michina iri pazasi.Ichi chimiro chakanakira debug.
2. Complex insulating chimiro uchishandisa mweya uye organic zvinhu;Compact dimension uye huremu hudiki.
3. Vacuum arc-extinguish chamber yeCutler-Hammer Company (USA) neZMD yemumba zvese zvinoshanda kuVCB.Ese maviri marudzi maviri emakamuri anodzima arc neakamira magineti uye aine yakadzikira-kuchekwa uye yakanaka yeku-off kugona neasymmetry.
4. Chitubu chekushanda chiri nyore hachina kuchengetedzwa mukati me10000 nguva dzekushanda.
5. Lead-screw propeller, nyore uye yakagadzikana kushanda uye yakanaka yekuzvivharira kugona.
