EM Group Tubular Ring Terminal 70mm² M10 Unplated Copper

The EM Group Tubular Ring Terminal 70mm² M10 is a professional-grade electrical component engineered for secure and efficient cable termination. Constructed from high-quality unplated copper, this terminal provides superior electrical conductivity and thermal performance, making it an essential part of robust power distribution and grounding systems. Its tubular design allows for precise cable insertion, ensuring a stable connection that withstands demanding industrial environments.

Advantages

The primary benefit of this tubular ring terminal is its exceptional material purity, which minimizes resistance and prevents overheating in high-current applications. The unplated copper construction offers a reliable contact surface that is ideal for permanent electrical installations. Its sturdy design ensures that the connection remains secure under mechanical stress, while the M10 stud hole provides compatibility with standard industrial bolts and busbars.

Suitable for

• Power distribution panels
• Grounding and earthing systems
• Industrial machinery wiring
• Commercial electrical installations
• Battery bank connections

When it may not be suitable

This terminal is not intended for use in highly corrosive environments where oxidation of unplated copper could compromise the connection over time. It is also not suitable for applications requiring specific plating, such as tin-plated terminals for enhanced corrosion resistance in marine or outdoor settings.

Key specifications

• Cable cross-section: 70mm²
• Stud hole diameter: M10
• Material: Unplated copper
• Design: Tubular ring terminal

How to use

To install the terminal, first strip the insulation from the 70mm² cable to the appropriate length. Insert the conductor fully into the tubular barrel of the terminal. Use a professional hydraulic or mechanical crimping tool specifically rated for 70mm² tubular terminals to create a permanent, gas-tight connection. Once crimped, secure the ring end to the M10 stud using a bolt and washer, ensuring the connection is tightened to the manufacturer's recommended torque specifications.

What to consider before purchase

• Verify that your cable cross-section is exactly 70mm².
• Ensure the M10 stud size matches your connection point.
• Confirm that unplated copper is suitable for your specific environmental conditions.
• Check that you have access to a compatible heavy-duty crimping tool.

Usage recommendations

Always ensure that the crimping tool is correctly calibrated for the terminal size to prevent loose connections or conductor damage. Regularly inspect the connection point for signs of heat or oxidation in high-load applications.
