Abstract
An exemplary surge arrester includes a housing with protection against electric shock. A voltage-limiting active part is arranged in the housing and has a stack of varistor elements formed as a varistor column. An electrical connection is arranged outside the housing and is electrically conductively connected to the varistor column for connecting a high-voltage installation. The electrically conductive connection between the varistor column and the electrical connection is a flexible high-voltage cable conductor. The high-voltage cable has a first section arranged in the interior of the housing and formed without a shield, and a second section arranged outside the housing and having cable insulation and an electrically conductive shield that surrounds the cable conductor. The high voltage cable is electrically conductively connectable first to the housing and second to an encapsulation. The housing accommodates an apparatus for damping oscillations which are introduced into the varistor column from the outside.
