The main advantages of “SIMOPRIME”:

Personnel safety:

  • All switching operations including emergency manual switching is possible only in the closed position of the high-voltage compartment door
  • Blockings between the high-voltage compartment door and switching devices
  • Moving of the circuit breaker truck is possible only in the closed position of the high voltage cabinet doors
  • Metal grounded protective curtains and separation partitions, partition class: PM
  • Resistance to influence of internal arc up to 40 kA, 1 sec, according to IEC 62271-200
  • Application of vacuum circuit breakers

Reliability:

  • The switchboard is manufacture made, type tested, according to IEC 62271-200
  • Type testing of the circuit breaker mounted in the cell
  • The usage of standard components which are available worldwide
  • The usage of vacuum circuit-breakers which are not service required
  • The quality assurance system is certified according to ISO 9001 standards
  • Manufacturing process which is based on the best international practices

High performance:

  • Classification by LSC2B according to IEC 62271-200:

The possibility of the service operations without disruption of correct operation of neighboring cells thanks to a grounded metal safety shutters and separation partitions.

The usage of service-free vacuum circuit breakers.
