Abstract

A screening electrode, which is arranged under oil, for tap changes of tapped transformers, which screening electrode is designed as a closed ring which is wrapped with paper. The ring consists essentially of a grooved corrugated tube which is wound from strips consisting of aluminium foil which is longitudinally folded several times. The corrugated tube is filled with foam using a cured multi-component plastic foam (hard plastic foam).
