EM Group Tubular Ring Terminal 35mm² M10 Unplated Copper

The EM Group tubular ring terminal is a high-performance electrical component engineered for 35mm² conductors, specifically designed to accommodate M10 stud sizes. Crafted from premium-grade unplated copper, this terminal provides superior electrical conductivity and mechanical strength, making it an essential element for demanding power distribution and industrial wiring projects. Its tubular design facilitates a secure and permanent crimp, ensuring long-term reliability in various electrical systems.

Advantages

The primary benefit of this tubular ring terminal lies in its high-purity copper construction, which minimizes electrical resistance and prevents overheating during high-current operations. The robust tubular geometry allows for a uniform crimping process, creating a gas-tight connection that resists vibration and environmental stress. Its design is optimized for professional installations where safety and electrical efficiency are paramount, providing a stable interface for M10 bolt connections.

Suitable for

• Power distribution panels and switchgear
• Industrial machinery wiring
• Heavy-duty electrical grounding systems
• Battery cable terminations
• Renewable energy infrastructure

This terminal may not be suitable for applications involving highly corrosive environments where unplated copper might oxidize rapidly without additional protection. It is also not intended for use with conductors outside the specified 35mm² cross-section, as this would compromise the integrity of the crimped connection.

Key specifications

• Conductor cross-section: 35mm²
• Stud hole diameter: M10
• Material: Unplated copper
• Design: Tubular ring terminal

To use this terminal, strip the insulation from the 35mm² conductor to the appropriate length, ensuring the copper strands are clean and undamaged. Insert the conductor fully into the tubular barrel of the terminal. Use a professional-grade hydraulic or manual crimping tool compatible with tubular terminals to apply sufficient pressure, creating a secure mechanical and electrical bond. Once crimped, the terminal can be fastened to the M10 stud using a matching nut and washer.

What to consider before purchase

• Verify the conductor cross-section matches the 35mm² specification
• Ensure the M10 stud size is compatible with your existing hardware
• Check if the environment requires tin-plated terminals for corrosion resistance
• Confirm the availability of a compatible crimping tool for tubular terminals

Usage recommendations

Always ensure the crimping tool is properly calibrated for the specific terminal size to achieve a reliable connection. Periodically inspect the connection point for signs of oxidation or thermal stress in high-load applications.
