The programme of HVI Conductor system components consists of a HVI
product range of connecting and fixing elements for this conductor.

Installation and use
The HVI
®
Conductor is a high-voltage-resistant, insulated down conductor with a voltage-controlled
outer sheath.
It is typically used as insulated down conductor in lightning protection systems to maintain the separation
distance in accordance with IEC 62305 Part 3 (DIN EN 62305-3) (VDE 0185-305-3). At first, the separation
distance has to be calculated as explained in IEC 62305 Part 3 (DIN EN 62305-3 (VDE 0185-305-3),
Subclause 6.3, with a material factor of k m = 1 in air, or k m = 0.5 for solid material. It has to be tested
if this calculated separation distance can be realised with the equivalent separation distance of the
®
HVI
Conductor (see technical data, Table 1):
calculated separation distance ≤ equivalent separation distance.
If this is not the case, measures according to section 9 or 10 have to be taken.
The length for calculating the separation distance "s" has to be measured from the head piece (see Fig.
1, page 3) to the next level of lightning equipotential bonding, e.g. the earth-termination system.
