Ergom PMA 16 Al-Cu Bimetallic Washer

The Ergom PMA 16 Al-Cu bimetallic washer is a specialized component engineered to facilitate secure and durable electrical connections between aluminum and copper conductors. By acting as a transition interface, this washer effectively mitigates the risk of galvanic corrosion that typically occurs when dissimilar metals are joined directly. Its robust construction ensures stable electrical contact, making it a critical part of professional electrical infrastructure and power distribution systems.

Advantages

The primary benefit of the Ergom PMA 16 washer is its ability to prevent electrochemical degradation at the junction point of aluminum and copper. By providing a stable bimetallic interface, it maintains low contact resistance over time, which is essential for preventing overheating and potential system failures. The design is optimized for ease of installation, ensuring that electrical professionals can achieve reliable, long-lasting connections in diverse environmental conditions.

Suitable for

• Connecting aluminum cables to copper terminals
• Power distribution cabinets and switchgear
• Industrial electrical installations
• Renewable energy infrastructure projects

This washer may not be suitable for applications involving high-vibration environments where specific locking mechanisms are required, or for use with materials other than aluminum and copper. It is not intended for structural load-bearing applications and should only be used within the specified electrical parameters of the installation.

Key specifications

• Material: Bimetallic (Aluminum-Copper)
• Compatibility: Aluminum and copper conductors
• Function: Corrosion prevention in mixed-metal joints
• Application: Electrical contact transition

To use the Ergom PMA 16 washer, place it between the aluminum and copper surfaces during the fastening process. Ensure that the contact surfaces are clean and free of oxidation before installation. Tighten the connection to the manufacturer's recommended torque specifications to ensure optimal pressure and electrical conductivity across the interface.

What to consider before purchase

• Verify the conductor sizes match the washer dimensions
• Ensure the installation environment is compatible with bimetallic connections
• Check local electrical codes for specific requirements regarding mixed-metal joints

For best results, always ensure that the contact surfaces are properly prepared and that the connection is protected from moisture to further enhance the longevity of the electrical joint.
