Applications
- Power plants — indoor switchgear for receiving and distributing electric energy.
- Substations — single-bus sectioning and circuit control.
- Industrial and mining enterprises — distribution and protection of plant circuits.
- High-rise buildings — indoor distribution switchgear in tall buildings.
- Switching stations — combined with ring main units in switching station applications.
Installation Conditions
- The switchgear is an indoor complete device, so it must be installed inside a building rather than outdoors.
- The system must be three-phase AC at 50Hz within the 3.6–12kV range, with a single-bus sectioning arrangement.
- Confirm the voltage within the 3.6–12kV range before installation, as the device covers that band.
- Where the switchgear is to be combined with ring main units for a switching station, the combination must be planned as part of the installation layout.
How to Select
- The rated voltage required within the 3.6–12kV range.
- The number of circuits to be controlled, protected and monitored.
- The single-bus sectioning arrangement and the main busbar configuration.
- Whether the switchgear will be used alone or combined with ring main units in a switching station.
- The application type — power plant, substation, industrial and mining enterprise, or high-rise building.
