M-GKK Bus Coupling With Circuit Breaker Unit
Air Insulated Modular Switchgear Section
Air Insulated Modular Switchgear consists of 3 main sections. These sections are secured with keys and mechanical locks. Alongside this, continuous transitions are isolated from the other sections.
A-Low Voltage Section
This section contains every secondary circuit for control (measurement,preservation,tracing,communication and other related systems).
B-Cuting and Cable Section
Following equipments are used in Cuting Section:
- Vacuum Circuit Breaker -SF6 Circuit Breaker -SF6 Gas Load Break Switch
- SF6 Gas Disconnector -Voltage Transformer -Current Transformer
- Mid Voltage Fuse - Capacitive Voltage Divider
- Cable connector and connection components.
C-Busbar Section
Busbar section contains suitable electrolytic coppers, insulators and bushing insulators selected for nominal voltage. Access to this section requires special instructions and security precautions.
