Dehn 819638 HVI light plus Conductor D 21 mm Cu grey pre-assembled outside install. L 6 to 70m

HVI light plus Conductor (high-voltage-resistant, insulated down conductor) 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 (pre-assembled for installation outside the tube, grey), with one head piece and one earth connection element. Equivalent separation distance s ≤ 60 cm (in air); s ≤ 120 cm (solid material).
