Abstract

A laminated busbar includes: a base body comprising conducting layers and insulating material to electrically insulate the conducting layers from each other. The conducting layers and the insulating material are clamped together by mechanical means and/or a profile is connected to the base body. In an embodiment, no glue or adhesive is arranged between at least one conducting layer and at least one insulating material.

First claim

What is claimed is:

1. A laminated busbar, comprising:
a base body comprising conducting layers and insulating material to electrically insulate the conducting layers from each other,
wherein the conducting layers and the insulating material are clamped together by mechanical means,
wherein a profile is connected to the base body,
wherein insulation rings are disposed around the mechanical means in holes of the conducting layers, and
wherein the base body is connected to the profile by riveting or bolting.

2. The laminated busbar according to claim 1 , wherein no glue or adhesive is arranged between at least one conducting layer and at least one insulating material.

3. The laminated busbar according to claim 1 , wherein at least one conducting layer is connected to another conducting layer and to an insulating material by riveting or bolting, so that the rivets or bolts are the mechanical means.

4. The laminated busbar according to claim 1 , wherein at least one insulating material is connected to another insulating material and to a conducting layer by riveting or bolting, so that the rivets or bolts are the mechanical means.

5. The laminated busbar according to claim 1 , wherein at least one insulating material between two conducting layers comprises a plate.

6. The laminated busbar according to claim 1 , wherein the base body comprises a wall and is flat.

7. The laminated busbar according to claim 1 , wherein at least one profile is connected to an outer conducting layer in an electrically insulated manner or to an outer insulating material.

8. The laminated busbar according to claim 1 , wherein the profile comprises a G-profile.

9. An arrangement, comprising:
the laminated busbar according to claim 1 ; and
at least one profile or several profiles.

10. The arrangement according to claim 9 , wherein at least a component of a cabinet or a switchgear is connected to at least one profile.

11. The arrangement according to claim 9 , wherein at least a compartment or plate of a compartment is connected to at least one profile.

12. A switchgear, comprising:
the laminated busbar according to claim 1 .

13. The switchgear according to claim 12 , wherein the switchgear comprises a low voltage switchgear.

14. A switchgear, comprising:
the arrangement according to claim 9 .

15. The switchgear according to claim 14 , wherein the switchgear comprises a low voltage switchgear.
