Abstract: A high voltage surge arrester including insulating polymer housing with a protruding shed. The shed has an upper shed surface that forms a blunt angle with the longitudinal axis of the surge arrester and a lower shed surface. The lower shed surface includes an inner portion that forms an essentially right angle with said axis and an outer portion that forms an acute angle with said axis. Further the invention relates to an apparatus for moulding an electrically insulating polymer housing.
