EM Group Tubular Ring Terminal 35mm² M8 Tinned Copper

The EM Group tubular ring terminal is a high-performance electrical component engineered for the secure termination of 35mm² conductors. Designed for use with M8 studs, this terminal provides a robust and permanent connection point essential for professional electrical systems. The construction utilizes premium-grade copper, which is finished with a tin coating to enhance electrical conductivity and provide long-lasting protection against oxidation and environmental corrosion.

Advantages

This tubular ring terminal offers exceptional reliability in demanding electrical environments. The use of high-quality tinned copper ensures minimal resistance and efficient power transmission, reducing the risk of overheating at the connection point. Its tubular design allows for a tight, uniform crimp, ensuring that the conductor remains firmly attached even under mechanical stress or vibration. Furthermore, the tin plating provides superior resistance to moisture and chemical exposure, making it an ideal choice for both indoor and outdoor installations where durability is paramount.

Suitable for

• Power distribution panels and switchgear
• Grounding and earthing systems
• Automotive and marine electrical wiring
• Industrial machinery power connections
• Battery cable terminations

When it may not be suitable

This terminal is specifically designed for 35mm² conductors and is not suitable for cables of different gauges, as this would result in an insecure or unsafe connection. It is also not intended for use in environments where the operating temperature exceeds the thermal limits of the copper material or where the connection will be subjected to extreme mechanical pulling forces beyond standard electrical installation requirements.

Key specifications

• Conductor cross-section: 35mm²
• Stud hole diameter: M8
• Material: Tinned copper
• Connection type: Tubular ring

How to use

To install the terminal, first strip the insulation from the end of the 35mm² cable 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 35mm² tubular terminals to compress the barrel onto the wire, ensuring a gas-tight connection. Once crimped, place the ring end over the M8 stud and secure it firmly using a matching nut and washer to ensure optimal contact pressure.

What to consider before purchase

• Verify that your cable size is exactly 35mm²
• Ensure the M8 stud size matches your mounting hardware
• Confirm that you have the correct crimping tool for tubular terminals
• Check the environmental conditions to ensure tinned copper is appropriate for your application

Usage recommendations

For the most reliable results, always use a calibrated crimping tool designed for tubular terminals. Avoid using pliers or improper tools, as these can lead to loose connections and increased electrical resistance. Ensure the contact surface of the stud is clean and free of debris before tightening the connection.
