Supporting tube with integrated HVI
®
Conductor
(not HVI®long Conductor)
The
HVI
®
Conductor
installed inside the supporting tube (Part No. 819 320, 819 420, 819 322, 819
422, 819 323, 819 423 or 819 321, 819 324, 819 325, 819 425, 819 360, 819 361, 819 362) is typically
used for visually optimised places of installation.
Before installing the supporting tube, the pre-assembled
HVI
®
Conductor
has to be inserted into the
supporting tube as follows:
Installation with air-termination rods Ø 10 mm:
■
Insert the
HVI
®
Conductor
(turn it slightly, if required) so that the threaded pin (M10)
protrudes from the head of the supporting tube
■
Firmly screw the lock nut (M10) onto the threaded pin.
■
Tightly connect the hexagon connector (M10/M10 chamfer on top)) to the lock nut.
■
Screw the air-termination tip to the hexagon connector and lock it.
Installation with air-termination rods Ø 16/10 mm:
■
Insert the
HVI
®
Conductor
(turn it slightly, if required) so that the threaded pin (M10)
protrudes from the head of the supporting tube.
■
Firmly tighten the M10 female thread of the air-termination rod onto the threaded pin of the
HVI
®
Conductor
.
■
Tighten lateral M8 locking screw (10 Nm).
The internal EB connection is led out of the
HVI
®
Conductor
by means of a UV-resistant conductor
(6 mm
²
). This conductor is sealed with a cable lug (bore Ø 8.4 mm). If required, this conductor can be
shortened or extended. This conductor has to be connected to the equipotential bonding (Figure 9,
page 12).

Installation of conductors
The entire
HVI
®
Conductor
has to be installed in the protection area of the air-termination system of
the external lightning protection system (see Figure 7, page 10) and must not be connected to lightning
voltage conducting parts of the air-termination system, the down-conductor system or structural parts
(see Figure 3, page 5 and Figure 14, page 18).
An exception can be made if the separation distance ”s” at the crossover of the
HVI
®
Conductor
and
the part of the installation conducting lightning voltage (air-termination system, metal capping of the
roof parapet, down-conductor system) is
≤
0.35 m (in air) or
≤
0.7 m (in solid material). In this case,
the sheath of the
HVI
®
Conductor
can be connected to the lightning voltage conducting part (equivalent
electric strength).
Downstream of the sealing end range, the
HVI
®
Conductor
has to be fixed in spacings of
≤
1 m.
The fixing screws of metal conductor holders have to be tightened with max. 5 Nm, the fixing screws
of plastic conductor holders with max. 2 Nm.
If a
HVI
®
Conductor
is installed in the building, protection measures, e.g. fire barriers, have to be
observed.
