Air-insulated switchgear for secondary distribution systems

Cleverly switched – Air-insulated switchgear: Compact, reliable and safe operation

General Information

Description

Simosec switchgear with air-insulated technology – combined with gas-insulated switching functions – are factory-assembled, type-tested and metal-enclosed indoor switchgear according IEC.
Simosec switchgear is used for power distribution in distribution systems with feeder up to 1250 A. Modular space-saving design allows use in substations and customer transfer substations of power supply and public utilities as well as applications in industrial plants and public buildings, such as high-rise buildings, railway stations, hospitals.
