Ergom KO 70/8 Tinned Copper Ring Terminal

The Ergom KO 70/8 Tinned Copper Ring Terminal is a professional-grade electrical component designed to provide secure and efficient connections for heavy-duty wiring. Manufactured from high-quality copper and finished with a tin coating, this terminal is built to withstand demanding electrical environments while maintaining optimal conductivity. Its robust construction ensures that it remains stable under mechanical stress, making it a reliable choice for critical power distribution tasks.

Advantages

The primary benefit of this terminal is its superior material composition, which combines the high electrical conductivity of copper with the protective properties of a tin finish. This combination effectively prevents oxidation and corrosion, ensuring long-term performance even in challenging conditions. The ring design provides a large contact surface area, which minimizes electrical resistance and prevents overheating at the connection point. Furthermore, the precise engineering of the terminal allows for a consistent and firm crimp, which is essential for maintaining the integrity of electrical circuits over time.

Suitable for

• Professional electrical installations
• Power distribution systems
• Industrial wiring applications
• Battery cable connections
• Heavy machinery power supply

When it may not be suitable

This terminal is specifically designed for 70 mm² conductors and an 8 mm stud size. It is not suitable for cables with different cross-sections, as an improper fit will result in a poor electrical connection and potential safety hazards. Additionally, it should not be used in environments where the terminal material is incompatible with the surrounding chemical atmosphere.

Key specifications

• Conductor cross-section: 70 mm²
• Stud hole diameter: 8 mm
• Material: Tinned copper
• Connection type: Ring terminal

How to use

To use the Ergom KO 70/8 terminal, first strip the insulation from the end of the 70 mm² conductor to the appropriate length. Insert the conductor fully into the barrel of the terminal. Using a professional-grade hydraulic or manual crimping tool designed for this specific size, apply sufficient pressure to create a permanent, gas-tight connection. Once crimped, secure the ring end to the desired terminal block or stud using an 8 mm bolt and nut, 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 70 mm².
• Ensure the mounting stud diameter is 8 mm.
• Confirm that you have the correct crimping tool for this terminal size.
• Check the environmental conditions to ensure tinned copper is appropriate for your application.

Usage recommendations

Always inspect the crimped connection for any loose strands or signs of deformation before finalizing the installation. Ensure that the connection point is clean and free of debris to maintain maximum electrical contact.
