The CapCube solution successfully integrates an inrush PFC capacitor bank of up to 1 Mvar within a conventional UniSafe switchgear platform. This type of solution is ideal for medium voltage motor control centre (MCC) applications or any inrush PFC applications up to 12 kV.
OEMs with an established medium voltage air insulated switchgear (AIS) customer base will also benefit from the additional PFC solution with minimal effort and outlay.
The CapCube enables OEMs to expand their medium voltage product portfolio and offers customers a truly competitive product that combines a PFC unit with their existing switchgear line up.
