Bi-metal plates and washers are used for the connection between copper conductors and aluminum conductors to avoid corrosion leading to ineffective and unreliable connections.

Bi-metal plates and washers are used for the connection between copper conductors and aluminum conductors to avoid corrosion leading to ineffective and unreliable connections.

Inserting bimetallic Cu-AL plates or gaskets prevents problems: since these products are bimetallic (obtained by explosive welding), the copper and aluminum surfaces are molecularly connected, and there is no electrolyte corrosion that can trigger electrical currents.
