Abstract: A device comprising a group of electrode elements for a condenser separator of a two-step electrofilter, which group of electrode elements comprises at least two electrode elements in the form of strips or flat planar sheets, the electrode elements being mostly comprised of a core. At least one of the electrode elements or group of electrode elements is formed of at least two different polymers with different electrical properties. A first portion of the electrode element that is disposed closest to an adjacent second electrode element in the condenser separator is formed of an insulating polymer, and a second portion of the electrode element is comprised of at least one current conductive element in the form of a thin coating on the core of the electrode element, or is embedded in the core.

Abstract: A device comprising a group of electrode elements for two-step electrofilters in a condenser separator, which group of electrode elements comprises at least two strip shaped electrode elements (A, B), or two groups of planar disc-shaped electrode elements (A, B), the electrode elements (A, B) to a major part being comprised of a core (M1), and wherein at least one of the electrode elements (A, B) or group of electrode elements (A, B) is formed of at least two different polymers with different electrical properties, wherein a portion (M1, M3, M3?) of the electrode element (A) that is disposed closest to an adjacent second electrode element (B) in the condenser separator is formed of a polymer having a surface resistivity of more than 1×1012 ohm/kV, and wherein a second portion of the electrode elements (A, B) is comprised of at least one current conductive element (M2, M2?, M2?) in the form of a polymer in the form of a thin coating on the core (M1) of the electrode elements (A), or is embedded in said core (M
