Bus bar and bus bar set for distribution connections

摘要

The bus bar has a main branch (1A) made of aluminum and secondary branches (1B) made of copper or brass and connected with the main branch through a traversing element e.g. screw, made of steel. Contact zones between the main branch and the secondary branches are buried in a material insulating the contact zones from the atmosphere. The traversing element is engaged in a bore of the secondary branches and screwed in the main branch.
