Busbar fixing

A method for producing a conductor rail including at least one electrically conductive conductor rail element and an electrically insulating sheath, wherein the electrically insulating sheath comprises at least one first component and at least one second component, wherein the at least one first component comprises a material having an elastic modulus of greater than or equal to 1300 N/mm2, and wherein the at least one second component comprises a material having an elastic modulus of less than or equal to 300 N/mm2, said method comprising:

• providing at least one stiff electrically conductive conductor rail element with at least two coupling regions for mechanical fastening, and an intermediate region which is arranged between the at least two coupling regions, wherein the intermediate region comprises at least one first region and at least one second region and the at least one first region is a region which is configured for mechanical stresses to occur, and the at least one second region is a region which is configured for no mechanical stresses to occur;
• applying an electrically insulating sheath as a multiple piece sheath on the at least one electrically conductive conductor rail element by means of the following steps:
• applying at least one first component comprising the material having an elastic modulus of greater than or equal to 800 N/mm2, and
• applying at least one second component comprising the material having an elastic modulus of less than or equal to 300 N/mm2, wherein the at least one first component and the at least one second component each comprise independent segments of the multiple piece sheath.
