MEDIUM VOLTAGE SWITCHBOARD 12KV, 17,5KV, 24KV
Air-insulated type tested medium-voltage switchgear systems for 12kV, 17,5kV and 24kV operating voltage level.
Withdrawable unit technology for primary distribution applications.
Internal partitioning up to eight metal-clad function compartments ensures maximum personnel and equipment protection.
Design features and classification under standard IEC 62271-200.
The type-tested medium-voltage switchgear with withdrawable unit technology is also available as a duplex version. Switch cubicles can be arranged back-to-back or facing each other. High availability and security of supply distinguish this system design.
