SecoCube - 36kV Gas Insulated Medium Voltage Switchgear

SecoCube is an indoor, factory-assembled, metal-enclosed, cubicle type gas-insulated switchgear for single busbar applications. It incorporates the advanced technologies of mixed gas-insulated (SF6 + N2) and vacuum breakers, allowing the equipment to operate in a more reliable and environmentally friendly manner.


With modern digital manufacturing and automatic testing coupled with sensor, monitor and protection technology, SecoCube is ideal fit for power distribution demands. SecoCube is particularly suited to industries with high reliability requirements such as Power Networks, Mining, Rail Transportation, Petrochemical Plants, Wind Farms and Metropolitan Rail Systems.


  • 70% reduction in switchroom size
  • Maximum safety for operator and equipment
  • Easy installation
  • Low operation and maintenance cost

Modular Design

Each panel consists of several functional compartments: low voltage compartment, cable compartment, vacuum circuit breaker compartment, main busbar compartment, arc duct for the circuit breaker compartment, arc duct for the main busbar compartment and cable compartment etc. Each functional compartment is separated from other compartments by metallic partitions and many combinations are available without impacting the gas system. Benefits of the modular design include easy assembly and replacement combined with limited disruption in the event of a fault.


  • Low Voltage Control & Protection Compartment
  • Cable Compartment
  • Busbar Compartment
  • Vacuum Circuit Breaker Compartment
