The grading capacitor is available in the combination of high voltage circuit breakers which can be used for different functions. The multibreak circuit breakers can evenly distribute voltage across the contact points during normal and switching system operation. In increasing the switching capacity of the breaker, the grading capacitor may used. The energy requirement is 90 kV up to 300 kV. It has sealed construction and offers low maintenance. The external component of the capacitor is made of aluminum and inox steel. It features high customization range in compliance with international mechanical and electrical standards. The unit has great mechanical resistance against shock and vibration during CBs switching operation. The AIS circuit breakers are perfect for outdoor installation.
