• Prepare the Work Area
  • Clear any debris and ensure you have enough space to work safely.
• Disconnect Cable Connections
  • Carefully remove any terminal connections using the appropriate tools.
• Remove the Cable
  • Use cable pulling tools to safely extract the cable from its conduit.
  • Avoid excessive force to prevent damage to surrounding infrastructure.

Step 4: Install New High-Voltage Cables

• Select Appropriate Cables
  • Ensure the new cables meet the specifications for 150 kV systems.
• Install the Cable
  • Insert the new cable into the conduit.
  • Ensure it is properly seated and secure.
• Reconnect Cable Terminals
  • Use the appropriate tools to connect the terminals, ensuring a tight and secure fit.

Step 5: Conduct Testing and Verification

• Perform Insulation Resistance Testing
  • Use insulation testing equipment to verify cable integrity.
• Check Connections
  • Inspect all terminal connections for proper installation.
• Conduct a Final Voltage Test
  • Confirm that the circuit is ready to be energized by testing voltage levels.
