Bi-Metal Cupal Washers

It is known that when the Aluminium Terminals are directly connected to Copper Terminals
to carry current at a high voltage, a bimetallic galvanic corrosion occurs, resulting in a high
resistance at the joint. The heated joints are oxidized and loses contact resulting in sparks,
voltage dropout power losses and failure, damage to machinery.

Applications:
Substation accessories like Bimetalic clamp and connectors
Flexible connectors
Cable clamp and cable end connectors
Distribution and panel boards
Isolators and switchgears
Circuit Breakers
