Av qeeg siv: ≤8 degree;
Cov sij hawm siv tau yuav tsum tsis txhob muaj kab mob, tawg, corrosives thiab kev co hnyav.

Qauv

Tus qauv tsim

1. Lub arc-extinguish chamber yog nyob rau sab sauv thiab lub mechanism yog nyob rau hauv qis.Cov qauv no yooj yim rau kev debug.
2. Complex insulating qauv siv huab cua thiab cov khoom siv organic;Compact dimension thiab qhov hnyav me me.
3. Nqus arc-extinguish chamber ntawm Cutler-Hammer Company (USA) thiab domestic ZMD yog ob qho tib si siv rau VCB.Ob hom chambers extinguish arc los ntawm ntsug magnetic teb thiab featuring nrog tsawg txiav thiab zoo on-off muaj peev xwm nrog asymmetry.
4. Lub caij nplooj ntoos hlav ua haujlwm yooj yim yog pub dawb los ntawm kev saib xyuas tsis pub dhau 10000 lub sijhawm ua haujlwm.
5. Lead-screw propeller, kev ua haujlwm yooj yim thiab ruaj khov thiab muaj peev xwm kaw tus kheej zoo.
