EM Group Tubular Ring Terminal 70mm² M8 Unplated Copper

The EM Group tubular ring terminal is a high-performance electrical component engineered for the secure termination of 70mm² copper conductors. Constructed from high-quality unplated copper, this terminal provides superior electrical conductivity and mechanical strength, making it an essential element for demanding power distribution systems and industrial electrical installations.

Advantages

This tubular ring terminal offers exceptional reliability due to its robust copper construction, which ensures minimal resistance and efficient current flow. The design facilitates a precise and permanent crimped connection, reducing the risk of overheating or connection failure over time. Its unplated surface is ideal for applications where specific material compatibility is required, providing a stable and durable contact point for M8 bolt connections in various electrical enclosures.

Suitable for

• Power distribution panels and switchgear
• Industrial machinery and heavy-duty equipment
• Electrical grounding systems
• Connecting large-gauge copper cables to busbars or terminals

This terminal may not be suitable for environments with high levels of moisture or corrosive gases, as the unplated copper surface is susceptible to oxidation over time. It is also not intended for use with aluminum conductors, as this can lead to galvanic corrosion and connection failure.

Key specifications

• Conductor cross-section: 70mm²
• Bolt hole size: M8
• Material: Unplated copper
• Type: Tubular ring terminal

To install the terminal, first strip the insulation from the end of the 70mm² copper cable to the appropriate length. Insert the conductor fully into the tubular barrel of the terminal. Using a professional-grade hydraulic or manual crimping tool compatible with 70mm² terminals, apply sufficient pressure to create a solid, gas-tight connection. Ensure the terminal is properly aligned before tightening the M8 bolt to the specified torque.

What to consider before purchase

• Verify the cross-section of your cable matches the 70mm² specification
• Ensure the M8 bolt size is compatible with your existing equipment
• Check if your environment requires plated terminals for corrosion resistance
• Confirm you have the correct crimping tool for this terminal size

For optimal performance and safety, always use a calibrated crimping tool and ensure the cable is clean and free of oxidation before installation. Periodically inspect the connection for signs of heat or loosening in high-vibration environments.
