Switchboards

SIMOPRIME switchgear, up to 17.5 kV and up to 24 kV

• Type tested switchgear according to IEC 62271 200
• Use of high quality, world-wide available components
• Design based on global best practice and 50 years of experience

Technical benefits

• Interlockings between high voltage door and switching devices
• Rack in, rack out operations of the circuit breaker truck with high voltage door closed
• Metallic, earthed shutters and partitions, partition class: PM (metallic partition)
• Use of metallic, earthed shutters and partitions between the compartments
• Highest loss of service continuity of the switchgear (LSC2B according to IEC 62271 200) during maintenance
• Internal arc tested design according to IEC 62271 200, 17.5 kV up to 40 kA, 1 s
• Internal arc tested design according to IEC 62271 200, 24 kV, up to 25 kA, 1 s
• Use of maintenance free vacuum circuit breakers and vacuum contactors
• Flexibility due to two types of withdrawable unit design – Withdrawable (cassette) type – Truck type
• Easy production of SIMOPRIME switchgear due to basic design without need of complex jigs and fixtures
• Safe operation due to high-voltage door closed during all switching operations, including emergency manual operations

SIMOPRIME reliable medium-voltage switchgear for fail-safe operation
