## Long description

The Erko ACL 70-50/1 is a professional-grade sealed reduction connector engineered to facilitate secure and reliable electrical transitions between aluminum and copper conductors. By bridging the gap between 70mm² and 50mm² cable cross-sections, this component ensures consistent electrical performance while effectively mitigating the risk of galvanic corrosion that typically occurs when dissimilar metals are joined. Its robust construction makes it an essential element for maintaining the integrity of power distribution networks in various industrial and commercial environments.
Advantages
This connector offers superior protection against environmental factors, ensuring long-term stability of the electrical connection. The specialized design prevents oxidation at the contact point, which is critical for maintaining low resistance and preventing overheating in power lines. Its compact and durable build allows for efficient installation in tight spaces, providing a permanent solution that withstands mechanical stress and thermal expansion cycles.
Suitable for
Connecting aluminum power cables to copper conductors
Power distribution systems and electrical cabinets
Industrial electrical infrastructure projects
Outdoor installations requiring weather-resistant connections
When it may not be suitable
This connector is specifically designed for aluminum-to-copper transitions with defined cross-sections of 70mm² and 50mm². It is not intended for use with cables outside of these specific dimensions or for materials other than aluminum and copper. It should not be used in applications where the conductor type or size does not match the specified parameters.
Key specifications
Conductor compatibility: Aluminum and copper
Reduction range: 70mm² to 50mm²
Design: Sealed for environmental protection
Application: Electrical power distribution
How to use
To install the connector, ensure that the cable ends are properly stripped of insulation according to the manufacturer's guidelines. Insert the conductors into the respective sides of the connector, ensuring they are fully seated. Use appropriate professional crimping tools to apply the necessary pressure to create a permanent, gas-tight connection. Verify that the seal is intact to prevent moisture ingress.
What to consider before purchase
Verify the exact cross-section of your aluminum and copper cables
Ensure you have the correct professional crimping equipment
Check local electrical regulations for aluminum-copper connection standards
Usage recommendations
Always ensure that the contact surfaces of the conductors are clean and free of oxidation before insertion to maximize conductivity and connection longevity.
