When installing bare, uninsulated air-termination conductors directly on the roof, the separation distance to electrical and metal systems installed under the roof surface must be maintained in accordance with the state of the art and the current lightning protection standard DIN EN 62305-3 (VDE 0185-305-3). Cable installations, pipe systems and metal parts are frequently installed under the roofing in direct proximity to air-termination systems/down conductors, thus posing a proximity issue. The solution for these proximity issues is an isolated air-termination system with high-voltage-resistant, insulated down conductors.

– New system for the isolated air-termination system of transmitter/receiver systems (parabolic, terrestrial antennas) or whole buildings or building parts.
– Optically optimised routing of the HVI light Conductor inside the supporting tube, reduced dimensions of the supporting tubes (Al tube 40x5 mm) and low weight of the whole structure, also suitable for retrofitting on antenna poles
– Interior sealing end with a flexible StSt strip coming out at the bottom of the supporting tube, for connection to the equipotential bonding
– High-voltage-resistant insulated down conductor for maintaining the separation distance to electrically conductive parts as per DIN EN 62305-3 (VDE 0185-305-3)
– Equivalent separation distance s ≤ 45 cm (in air), or s ≤ 90 cm (solid building material)
– Supporting tube with insulating clearance made of glass-fibre reinforced plastic (GRP), tube Ø30 mm
– Material factor km = 0.7
– Light grey colour, UV-stabilised

The HVI light Conductor meets the requirements of DIN EN IEC 62561-8 (VDE 0185-561-8).
