Further information for Dehn + Soehne Dehn 819328 HVI 20 L6M SR3200 IP RFS2500 GRP AL HVI Ltg D20mm - HVI 20 M L6M SR3200
HVI cable (high-voltage-resistant insulated conductor) in a support tube, for maintaining 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 prevent creeping discharges, the HVI cable is equipped with a special external sheath that enables high lightning impulse voltages to be diverted to a reference potential. HVI cable design (black), with internal end closure and PA spring element in the support tube (length 3200 mm) with air-termination rod (D22 / 16 / 10 mm length 2500 mm), with a head piece, a PA connection element and an earth connection element. Equivalent separation distance s = 75 cm (in air), s = 150 cm (solid building material).
