Assembling the air-termination rod

Installing the potential connection on the end of the isCon
®
conductor
The black, weakly conductive layer of the isCon
®
conductor must be
included in the protective equipotential bonding of the building to be
protected (see Fig. 56 No.
1
). It is important that a specific minimum
distance (x) is maintained between the connection element of the isCon
®
conductor
2
on the conductor carrying the lightning current
3
and the
upstream potential connection terminal
4
, in order to prevent surface dis-
charge along the high-voltage-resistant isCon® conductor.
Note!
When the isCon Basic 45 conductor is installed, there is no equipotential
bonding connection on the air-termination rod
5
(see “6.6.1 Installing the
potential connection on an insulated air-termination rod” on page 50).

Minimum distance (x) between the connection element and the
equipotential bonding
Note!
The minimum distance (x) can be derived from the calculated separation
distance (see “4.2 Calculating, checking and maintaining the separation
distance” on page 23). Use the
formula x = s * 2
, in order to calculate
the minimum distance (x) necessary (see also Fig. 57).
