Abstract
A composite pane is described. The composite pane has a first pane, at least one intermediate layer, a second pane, a transparent, electrically conductive first coating between the intermediate layer and the first pane and/or between the intermediate layer and the second pane, a first busbar and a second busbar, and a transparent, electrically conductive second coating.
Claims20
A composite pane, comprising:
- a first pane, at least one intermediate layer, and second pane,
- a transparent, electrically conductive first coating between the at least one intermediate layer and the first pane and/or between the at least one intermediate layer and the second pane, and
- a first busbar and a second busbar, which are connected to the transparent, electrically conductive first coating, the first busbar being connected to a ground potential and the second busbar being connected to a DC voltage of 75 V to 450 V or an AC voltage of 25 V to 450 V,
- wherein an area of the transparent, electrically conductive first coating and an area of a transparent, electrically conductive second coating are arranged one over another with at least 80% congruence and insulated from each other, and
- the transparent, electrically conductive second coating is connected via at least one third busbar to the ground potential.
