Ring Terminal Ergom KOR 70/8 tinned copper — suitable for 70 mm² conductor, 8 mm bolt

Ergom KOR 70/8 is a tinned copper ring terminal engineered for crimp termination of 70 mm² conductors and bolted connection with an 8 mm fastener. The tin plating improves corrosion resistance and ensures consistent electrical contact for power cable terminations in industrial, automotive and electrical installations where a secure bolted joint is required.

Advantages

The tinned copper construction combines good conductivity with enhanced protection against oxidation. The ring design allows stable mechanical fastening with an 8 mm bolt, reducing the risk of loosening under vibration. The terminal is shaped for reliable crimping to 70 mm² conductors and provides a compact, low-profile connection point suitable for busbars, terminal blocks and grounding points.

Suitable for

• Power cable terminations on industrial switchgear and distribution panels
• Automotive battery and starter cable connections requiring secure bolted joints
• Grounding and earthing connections where corrosion resistance is needed
• Electrical installations with 70 mm² conductors and 8 mm bolt mounting

Key specifications

• Conductor cross-section compatibility: 70 mm²
• Bolt diameter for fastening: 8 mm
• Material: copper with tin plating
• Application type: crimp ring terminal for bolted connections
• Typical uses: power distribution, grounding, vehicle electrical systems

How to use

Strip the conductor to the appropriate length, insert the bare conductor fully into the barrel of the ring terminal, and perform a crimp using a suitable crimping tool sized for 70 mm² conductors. Position the ring over an 8 mm bolt or stud and fasten with the appropriate nut and washer to the recommended torque for the installation. Ensure the contact surfaces are clean and that the crimp is mechanically secure before energizing the circuit.

Usage recommendations

Use a certified crimping tool matched to the terminal size and conductor cross-section to achieve a reliable electrical and mechanical connection. Inspect crimps and bolted joints periodically for signs of corrosion or loosening, and replace terminals that show damage or excessive wear.
