Aluminum-Copper Washers – A Reliable Connector for Installers and Users

ACP 12-1/50 bimetallic washers are a key element ensuring a durable and safe connection of copper and aluminum wires. They prevent galvanic corrosion, a common problem in electrical installations using different metals. This ensures stable and trouble-free operation of the installation for a long time.

Construction and Application

Made from a combination of copper (CuZn40Pb2 – CW617N) and aluminum, these washers eliminate the risk of electrochemical cells forming at the interface of two different metals. This translates to minimizing energy losses and increasing user safety. They are ideal for use in distribution boards, connection boxes, and anywhere a connection between wires made of different materials is necessary. The inner diameter of 13 mm is adapted to metric screws size 12, and the outer diameter of 28 mm ensures stable seating. A thickness of 1 mm guarantees adequate mechanical strength.

Advantages and Benefits

• Elimination of galvanic corrosion: Prevents damage to the installation caused by the electrochemical potential difference between copper and aluminum.
• Durable connection: Provides a stable and reliable connection of wires, minimizing the risk of loosening connections.
• Versatility: Suitable for use with various types of copper and aluminum wires.
• Easy installation: Simple construction facilitates quick and efficient installation, saving the installer time.
• Raw state: Allows for adaptation of surface protection to specific installation requirements.
• High-quality material: The use of E-Cu copper and aluminum ensures long-term reliability and resistance to environmental conditions.
• Optimal size: The inner diameter of 13mm fits perfectly with M12 screws, providing a secure fastening.
