Siemens SIMOPRIME Technology Partner
SIMOPRIME medium-voltage switchgear, built by SEGA M
Type-tested, metal-clad, air-insulated switchgear from 7.2 kV to 24 kV with withdrawable vacuum circuit-breakers. No SF6 gas, all switching behind a closed door.
Designed around the operator
Internal arc classified
IAC A FLR up to 40 kA for 1 s. Every switching operation is done with the high-voltage door closed.
Maintenance on a live switchboard
LSC2B service continuity with earthed metal shutters, so adjacent panels stay energised during work.
Vacuum, no SF6
Maintenance-free vacuum circuit-breakers. No SF6 gas and no heat-shrink insulation that ages.
Withdrawable trucks
Each circuit-breaker sits on its own truck and is exchanged without switching off the busbar.

Questions buyers ask us
Which voltages do you build?
SIMOPRIME from 7.2 kV to 17.5 kV (12 kV type) and SIMOPRIME A4 for 24 kV. We do not build switchgear above 24 kV.
Does SIMOPRIME use SF6?
No. It is air-insulated switchgear with vacuum circuit-breakers.
Is the switchgear type tested?
Yes, SIMOPRIME is type tested to IEC 62271-200 with internal arc classification.
Can you supply the low-voltage side too?
Yes. We build SIVACON S8 switchboards and SIBOARD distribution boards in the same factory, so one supplier covers the whole substation.
