Dehn 819688 Supporting tube w. HVI light pl. a. air- term. tip f. rafter/metal roof bracket SET

HVI light plus Conductor (high-voltage-resistant, insulated down conductor) in the supporting tube for maintaining the separation distance from electrically conductive parts as per DIN EN 62305-3 (VDE 0185-305-3) to prevent dangerous flashovers between parts of the external lightning protection and internal conductive parts (electrical installation, pipelines, etc.). To prevent creeping discharge, the HVI light plus Conductor features a special outer sheath which allows high lightning impulse voltages to be discharged to a reference potential. HVI light plus Conductor version (grey) with internal sealing end in the supporting tube (length 2,680 mm) with air-termination tip (Ø10 mm, length 1,000 mm) and an earth connection element. Equivalent separation distance s ≤ 60 cm (in air); s ≤ 120 cm (solid material).
