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.
