Middle Voltage Vacuum Circuit Breakers Advantage:

Vacuum circuit breakers insulation test: Main electricity loop insulation is stable and reliable;

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

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

Middle voltage circuit breakersTesting for Turning on or off and opening or closing on rated short circuit :

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

Circuit breakers Testing for short-time withstand current and peak withstand current:

Vacuum circuit breakers test for 4 seconds withstand current and short-time peak withstand current, power receiving ability on main loop is great;

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