## Long description

The Erko ACK 12-70/1 is a high-quality sealed ring terminal specifically engineered for connecting aluminum and copper conductors. Designed for a 70mm² cross-section, this terminal provides a robust and reliable interface for power distribution systems. Its specialized construction effectively bridges the gap between different metal types, preventing galvanic corrosion and ensuring long-term electrical stability in demanding environments.
Advantages
This terminal offers exceptional protection against environmental factors due to its sealed design, which prevents moisture and contaminants from reaching the conductor. By utilizing advanced materials and manufacturing techniques, it ensures low contact resistance and high conductivity, which are essential for maintaining the integrity of electrical circuits. The design facilitates a secure mechanical connection that withstands vibrations and thermal expansion, making it a dependable choice for critical infrastructure.
Suitable for
Industrial power distribution networks
Connecting aluminum cables to copper busbars
Outdoor electrical installations requiring moisture protection
Heavy-duty electrical equipment and machinery
This terminal may not be suitable for applications involving extremely high-frequency signals or environments where the cable cross-section does not match the 70mm² specification. It is also not intended for use with non-compatible conductor materials or in conditions exceeding the thermal and mechanical ratings of the terminal.
Key specifications
Conductor cross-section: 70mm²
Material: Aluminum-Copper (Al-Cu)
Design: Sealed ring terminal
Application: Electrical cable termination
To use the Erko ACK 12-70/1, ensure the cable is properly stripped to the required length without damaging the individual strands. Insert the conductor fully into the terminal barrel and use the appropriate crimping tool designed for Al-Cu terminals to achieve a secure, gas-tight connection. Proper crimping pressure is vital to ensure the mechanical strength and electrical conductivity of the joint.
What to consider before purchase
Verify that your cable cross-section is exactly 70mm²
Ensure you have the correct crimping tool compatible with Al-Cu terminals
Check the mounting bolt size for the ring terminal hole
Confirm the environmental conditions match the sealed rating of the product
Always follow the manufacturer's installation guidelines and local electrical codes when performing cable terminations to ensure safety and compliance. Regular inspection of the connection point is recommended in high-vibration environments.
