With this invitation to participate Fingrid is looking for capable and interested suppliers of vibration dampers. In our operating model, the network of service and goods suppliers and good co-operation with suppliers are especially important. We require all our contractual partners who supply us with services or goods to be aware of Fingrid’s significant social duty and to commit to responsibility for the economic, social and environmental effects of their operations.

Vibration dampers are used to prevent busbar aeolian vibration which is caused by vortex shedding at the first and second natural frequencies of the busbar.
