Film/Foil Construction with Metallized Electrode Carrier Film

The capacitor is constructed as a series connection, the current carrying electrodes consist of two metal foils and a metallized carrier film as a "floating electrode".

After schoopage and bonding the wires are connected with all the edges of the winding element. The floating electrode only carries current through capacitive coupling. In this way, the advantage of self-healing (by means of the metallized floating electrode) is combined with the advantage of the exceptionally safe bonding of the metal foil.
Thanks to the series connection, the value of the corona inception voltage is doubled.

Capacitors constructed in this way are suitable for very high rated currents with a maximum of operating safety.

Advantages:
Highest pulse loading capacity due to very good bonding (metal foil electrode and metallized electrode carrier film).
Good self-healing properties thanks to the metallized carrier film floating electrode.
Due to the series connection, the value of the corona inception voltage is doubled.
