Power and grounding connections
A flexible power connection is needed in places where a rigid connection cannot be used due to the thermal expansion, vibration, or movement of the busbar
The connection is also suitable for applications where there is no complete certainty about the accuracy of the installation dimensions.
The connection surfaces of COREX power connections, depending on the type, are made of pure copper, tinned, or silver-plated. Standard types of flexible power connections with their dimensions are presented in the product catalog at the end of this page. Additionally, connections are manufactured on order according to the customer's drawings.
