Outdoor Intelligent Electric Vacuum Type Circuit Breaker Advantage:

electric disconnector equipment insulation test: Main electricity loop insulation is stable and reliable;

Mechanical property and environmental testing: mechanical property is stable and reliable;

Temperature rise test: Vacuum interrupter with ultra-low resistance, contacting resistance is low;

Testing for Turning on or off and opening or closing on rated short circuit :

High vacuum breaking ability is great, insulation recovery is fast, breaker finished short-circuit current test for 30 times;

electric disconnector equipment testing for short-time withstand current and peak withstand current:

electric disconnector equipment test for 4 seconds withstand current and short-time peak withstand current, power receiving ability on main loop is great.

electric disconnector equipment Testing for life : 30000 times finished on State new standard M2 grade.
