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.

Abstract: A multi-phase busbar for conducting electric energy includes: an insulating base layer made of an insulating material; a first conducting layer made of a sheet metal arranged on and adhesively bonded to the base layer; a first connecting pin mounted to the first conducting layer which extends in a direction with respect to the first conducting layer; a first insulating layer arranged on and adhesively bonded to the first conducting layer; a second conducting layer made of a sheet metal arranged on and adhesively bonded to the first insulating layer, the second conducting layer including a second connecting pin which extends in a direction parallel to the first connecting pin; and a second insulating layer arranged on and adhesively bonded to the second conducting layer. The second conducting layer and the first and second insulating layer each include at least one pinhole through which the first connecting pin projects.

Abstract: A multi-phase busbar can include a first conducting layer, a first conducting pin, a first insulating layer, and a second conducting layer. The first conducting layer can include a sheet metal coated with an electrically insulating material. The first conducting pin can be mounted to the first conducting layer. The first conducting pin can extend in a direction perpendicular to the first conducting layer. The first insulating layer of a rigid insulating material can be arranged on the first conducting layer. The first insulating layer can define an opening through which the first conducting pin projects. The second conducting layer can include a sheet metal coated with an electrically insulating material, the second conducting layer comprising a first pinhole through which the first conducting pin projects and a second conducting pin which extends in a direction parallel to the first conducting pin.

Abstract: An electrical transformer includes a coil pack including windings, and spacers axially spacing turns of the windings from one another and being formed of a thermoplastic material. Sticks couple and position the spacers. The coil pack has high resistivity to creep and permits temperature rise without degradation of transformer insulation, providing for extended service life and unique methods of transformer system upgrade.
