HVI cable (high-voltage insulated lead) in the support tube, for keeping the separation distance from electrically conductive parts according to DIN EN 62305-3 (VDE 0185-305-3) in order to prevent dangerous rollovers between parts of the external lightning protection and internal conductive parts (electrical system, piping, etc.). To prevent sliding discharge, the HVI cable is equipped with a special outer sheath that allows high flash pulse voltages to be controlled against a reference potential. Type HVI cable (gray), with internal end cap and PA spring element in support tube (length 3200 mm) with support rod (D22 /16 / 10 mm length 2500 mm), earth connection element and tripod stand. Equivalent separation distance s ? 75 cm (in air), s ? 150 cm (fixed construction material)
