DescriptionSIMOSEC switchgear is a factory-assembled, type-tested, three –phase, metal-enclosed, indoor switchgear according to IEC 62271-200 for single busbars .
all parts of SIMOSEC switchgear without the core part manufactured inside the factory of groups of Raban Al Safina companies in Iraq according to license agreement from Siemens Germany to manufacture the SIMOSEC IEC.
Typical uses - SIMOSEC switchgear issued for power distribution in distribution systems with feeder currents up to 1250 A. Modular space- saving design allows use in- Substations, customer transfer substations, distribution substations and switching substations of power supply and public utilities- Public buildings, such as high-rise buildings, railway stations, hospitals- Industrial plants
Modular design • Individual panels, for free combination and extension• Option: Low-voltage compartments can be supplied in two overall heights
• Air-insulated indoor switchgear• Gas-insulated, maintenance free switching functions for the three-position switch• Partition class: PM (metallic partition)• Three-pole primary enclosure• Phases arranged one behind the other• No cross-insulation between phases• Busbar system at the top• Air-insulated busbar and cable connection system• Three-position switch, metal enclosed, with air-insulated primary terminals and gas insulated switching functions• Vacuum circuit-breaker 3AH5, metal-enclosed, up to 630 A, fixed-mounted in gas-insulated switchgear vessel• Vacuum circuit-breaker 3AH6, air-insulated, up to 1250 A, easy to remove after loosening the fixing bolts• Hermetically-sealed by welding, stainless-steel switchgear vessel,
