Highly flexible connection and joining elements - Highly flexible connections made of copper fabric strip - Highly flexible connections made of copper round strand - Connection and joining pieces made of copper fabric strip - Connection and joining pieces made of copper round strand Technical explanations Wherever severe vibrations occur - such as in the switching of large contactors, automatic power switches etc. - the only way to ensure faultless operation is to employ highly flexible joining pieces. Recommendations for product selection Highly flexible expansion joints - are extremely resistant against vibrations and switching impulses; - make mounting easier by compensating for dimensional errors; - need more room to install than thin strips/foil joints.
