## Long description

The Erko ACP 14-1 bimetallic Cu-Al washer is a specialized component engineered to facilitate secure and reliable electrical connections when joining copper and aluminum conductors. By acting as a transition interface, these washers effectively mitigate the risk of galvanic corrosion that typically occurs when dissimilar metals are in direct contact. This set includes 50 high-quality washers, ensuring that electrical installations maintain optimal contact conductivity and long-term stability in mixed-metal wiring systems.
Advantages
The primary benefit of using these bimetallic washers is the prevention of electrochemical degradation at the junction point of copper and aluminum wires. By providing a stable, conductive bridge, the washers ensure that the electrical connection remains consistent over time, reducing the risk of overheating or increased resistance. Their robust construction allows for easy integration into standard electrical assemblies, providing a professional solution for complex wiring requirements.
Suitable for
Connecting copper conductors to aluminum busbars or terminals
Electrical distribution boards and switchgear assemblies
Industrial electrical maintenance and repair
Mixed-metal wiring systems in residential and commercial buildings
When it may not be suitable
These washers are specifically designed for copper-to-aluminum transitions and are not intended for use in environments where the connection is exposed to extreme chemical corrosives that exceed standard industrial ratings. They should not be used in applications where the mechanical load on the connection exceeds the structural capacity of the washer material.
Key specifications
Material: Bimetallic copper-aluminum (Cu-Al)
Quantity: 50 pieces per pack
