high voltage AC live tank circuit breaker is developed on the basis of GB1984 High Voltage Alternating-
current Circuit-breakers and IEC62271-100 High-voltage Switchgear and Controlgear Part 100. It is an
outdoor three-phase AC high-voltage electrical equipment used for the control and protection of the power
systems, and it can be used as the contact circuit breaker. This product adopts the principle of “compressed air +
thermal expansion” to extinguish the arc, with high breaking capacity, long mechanical life, easy maintenance
and high reliability.
