Belleville spring washers are used by power producing and transmission companies to keep a variety of bolted connections tight and secure.  The most common of these involve transformers and bus bars. 

The Belleville washer retains a spring force that provides adequate tension to help keep connections intact when loosening of the bolts and nuts occurs from excess vibration or heat transfer.  These basic applications are helping many power producing companies maintain strong service and peak operating efficiency.
