Abstract

The invention relates to a terminal corona protection device (10), in which an electrically conductive coating (EGS) which effects the terminal corona protection (EGS) is arranged on an electrically insulating sheath (14) of an electrically conductive device (12), the specific electrical resistance of said coating being greater than that of a material of the conductive device (12), wherein an electrically insulating heat conducting layer (42) is arranged on the coating and has a thermal conductivity level which is at least as great as a thermal conductivity level of the coating effecting the terminal corona protection (TCP).
