Claim 0:
1. A condenser core for being positioned around a high voltage main electrical conductor, the condenser core comprising:
an electrically insulating body;
a longitudinal through hole for accommodating the main electrical conductor;
a plurality of electrically conductive foils encircling the through hole and being surrounded by the body such that each foil is insulated from any other of the foils; and
a potential electrical conductor for establishing an electrical connection between one of the foils and the main electrical conductor when the main electrical conductor is accommodated in the through hole;
wherein the condenser core further comprises a fastening device, wherein the fastening device is configured to mechanically connect the potential electrical conductor to the main electrical conductor when the main electrical conductor is accommodated in the through hole and wherein the fastening device comprises a fastener and a washer for being pressed by the fastener such that the washer presses the potential electrical conductor against the main electrical conductor and the washer is countersunk.
