EM Group Tubular Ring Terminal 25mm² M10 Unplated Copper

The EM Group tubular ring terminal is a high-quality electrical component engineered for the secure termination of 25mm² conductors. Designed with an M10 stud hole, this terminal is crafted from premium unplated copper, providing superior electrical conductivity and mechanical strength. It serves as a reliable solution for establishing permanent, low-resistance connections in demanding electrical environments.

Advantages

This tubular ring terminal offers exceptional performance due to its robust construction from high-purity copper. The unplated finish ensures optimal contact surfaces for electrical current flow, minimizing energy loss and heat generation. Its tubular design allows for easy insertion of the conductor, facilitating a strong crimped connection that resists vibration and mechanical stress, making it a dependable choice for long-term electrical infrastructure projects.

Suitable for

• Power distribution cabinets and switchgear
• Grounding and earthing systems
• Industrial electrical wiring and machinery
• Battery cable connections

When it may not be suitable

This terminal is not intended for use in highly corrosive environments where oxidation of unplated copper could occur, as it lacks a protective tin coating. It is also not suitable for applications requiring aluminum conductors without the use of appropriate bimetallic transition adapters.

Key specifications

• Conductor cross-section: 25mm²
• Stud hole diameter: M10
• Material: Unplated copper
• Design: Tubular ring type

How to use

To install the terminal, first strip the insulation from the 25mm² conductor to the appropriate length. Insert the conductor fully into the tubular barrel of the terminal. Use a professional-grade crimping tool compatible with the terminal size to compress the barrel firmly onto the wire, ensuring a gas-tight connection. Once crimped, secure the ring end onto the M10 stud using a suitable nut and washer, ensuring the connection is tightened to the manufacturer's recommended torque specifications.

What to consider before purchase

• Verify the conductor cross-section matches the 25mm² rating
• Ensure the M10 stud size is compatible with your connection point
• Assess the environmental conditions to determine if unplated copper is appropriate
• Ensure you have the correct crimping tool for tubular terminals

Usage recommendations

Always ensure the crimping tool is properly calibrated for the specific terminal size to guarantee a secure and safe electrical connection. Inspect the connection periodically for signs of oxidation or loosening in high-vibration environments.
