HVI cable (high-voltage-resistant insulated conductor) in a support tube, to maintain the separation distance from electrically conductive parts in accordance with DIN EN 62305-3 (VDE 0185-305-3) in order to prevent dangerous flashovers between parts of the external lightning protection and internal, conductive parts (electrical system, pipes, etc.). To avoid creeping discharges, the HVI cable is equipped with a special external sheath that makes it possible to divert high lightning impulse voltages to a reference potential. HVI cable design (gray), with internal end closure and PA spring element in the support tube (length 3200 mm) with air terminal (D10 mm length 1000 mm), earth connection element and tripod with threaded rod set. Equivalent separation distance s 75 cm (in air), s 150 cm (solid building material).
