Lightning arrester for use in building, has transient and contact section in direction of lightning catch unit, where section comprises conductive cover that stays in communication with the conductor

摘要

The arrester has a metallic conductor (1) surrounded with a high voltage firm isolation coating or lamination (2) in a contact risk region. A transient and contact section is provided in a direction of a lightning catch unit, where the section comprises a conductive cover. The cover stays in communication with the conductor. A field intensity -transition region is realized between the isolation coating and the conductor.
