36/40.5kV Solutions

36/40.5kV Solutions
SFA-RM36 type switchgears; compact or modular SF6 GAS INSULATED switching and control arrangements designed for medium voltage electricity distribution networks.

• Hermetically sealed pressure system, leakage rate less than % 0.5 per year,
• After operation, it is possible to check the position of earthing switch (closed or not) via a surveillance window visually.
• Lower filling SF6 gas pressure (1.05 bar)
• 1 atmosphere pressure: (1,013 bar)
• Consecutive interlocking systems prevent incorrect operation. Access to the cable compartment and fuse compartment is only possible if the related earthing switch/switches is on the earthed position.
