1. Application of HVI®power Conductors

To avoid dangerous ashover between parts of the external lightning protection system and internal in-

stallations such as conductive parts (electrical installation, pipework, etc.), the separation distance “s”

must be observed when installing lightning protection systems.

High impulse voltages cause ashover on the surface of insulating material if no additional measures

are taken. This effect is also referred to as creeping ashover. If the creeping discharge inception volta-

ge is exceeded, a surface discharge is initiated which can easily ash over a distance of several metres.

To prevent creeping discharges, HVI®power Conductors feature a special outer sheath which allows

high lightning impulse voltages to be discharged to a reference potential. For functional reasons, a

connection is established in the sealing end range between the semiconductive outer sheath and the

building’s equipotential bonding system (no lightning voltage). This connection to the functional equi-

potential bonding system can be made e.g. at earthed metal roof-mounted structures located in the

protected zone of the lightning protection system, earthed parts of the building’s structure that do not

carry lightning voltage or the protective conductor of the low-voltage system.

No conductive or earthed parts may be located in the sensitive sealing end range within the

separation distance “s”.

2. Safety notes

IEC 60417-6182:

Installation,

electrotechnical expertise

ÂHVI®power Conductors may only be installed under the conditions shown and referred to in these

installation instructions.

ÂOnly qualied and trained personnel (lightning protection specialists) may install HVI®power Con-

ductors. We recommend to visit a special training course on HVI® products held by DEHN + SÖHNE

(http://www.dehn.de/de/dehnacademy).

ÂFor safety reasons, installation work must be stopped as soon as a thunderstorm approaches / is

noticed.

The components of the HVI®power system have been tested as a complete system. Mixing com-

ponents of the HVI®power system with components from other manufacturers is not permitted.

ÂPrior to installation, HVI®power Conductors must be examined for good order and condition. If da-

mage or any other defect is found, HVI®power Conductors must not be installed. The black sheath

of HVI®power Conductors must not be damaged by compressive deformation or cuts.

ÂWhen using HVI®power Conductors re and explosion protection measures must be taken.

ÂIf HVI®power Conductors are installed on thatched roofs (e.g. reed, straw), special installation

conditions must be observed for these ammable locations. The special installation conditions for

HVI Conductors are described in our Lightning Protection / Earthing main catalogue (HVI Lightning

Protection for Thatched Roofs). These conditions also apply to HVI®power Conductors.

ÂIf the supporting tube is led through a roof, the roof must be properly sealed. Warm roofs must be

properly sealed and insulated.

ÂHVI®power Conductors are suitable for outdoor use and can be installed downstream of the

sealing end e.g. on roofs, in walls, in concrete (mechanically protected, if required) or on facades /

facade constructions. However, the conductors are not suitable for permanent exposure to moisture.

HVI®power Conductors must not be installed in the soil.

ÂSoiled HVI®power Conductors can be cleaned with a cloth soaked with a special cleaning agent

(Part No. 297 199). To be able to comply with dangerous goods regulations, this product is only

transported within Germany and Austria. ISOPROPYL ALCOHOL (99.1 to 99.9 %) (CSA No. 67-63.0)

can be used as an alternative!

ÂHVI®power Conductors must not be painted due to the special design of the outer sheath.

ÂThe function of HVI®power Conductors is to maintain the separation distance. They do not have a

magnetic shielding effect due to their design. Therefore, induction effects in secondary conductors /

loops must be observed. If required, surge protection measures must be taken.

ÂFor application-specic questions, please contact the relevant sales team or the DEHN representati-

ve in your country.

ÂIt has not yet been checked whether HVI®power Conductors are suitable for use in hazardous

areas. Therefore, it is not allowed to use HVI®power Conductors in these areas.

3. SpecicationofHVI®power Conductors

3.1 Design of HVI®power Conductors

HVI®power Conductors are high-voltage-resistant, insulated down conductors with a semiconducti-

ve outer sheath (see Fig. 1).

They are typically used as insulated down conductors for lightning protection systems to maintain the

separation distance in accordance with IEC 62305-3. At rst, the separation distance “s” must be

calculated as described in 6.3 of the IEC 62305-3standard using a material factor km = 1 in air, or km

= 0.5 for solid material. It must be checked whether this calculated separation distance can be imple-

mented by means of the equivalent separation distance of the HVI®power Conductor (see technical

data, Table 1, page 7):

calculatedseparationdistance≤equivalentseparationdistance.

If this is not the case, the measures described in 6.3, page 22 must be taken.

The length which is required for calculating the separation distance “s” is measured from the head

piece to the next lightning equipotential bonding level, e.g. the earth-termination system.

In case of a down conductor with kc = 1, the following maximum conductor lengths are permitted de-

pending on the class of LPS:

LPS I max. 11.25 m

LPS II max. 15.0 m

LPS III max. 22.5 m

4. Different types

The component range of the HVI®power Conductor system consists of a HVI®power Conductor and

a range of connection and xing elements matched to this conductor. Special know-how is required to

design and install HVI®power Conductors. HVI®power Conductors are available as pre-assembled

conductors or on a 100 m reel (HVI®power long). More detailed information about the component

range of the HVI®power Conductor system can be found in our brochures DS210/E and DS212/E, our

Lightning Protection / Earthing main catalogue or at www.dehn-international.com.

As a basic principle, all HVI®power Conductors can be shortened, but not extended!

4.1 Pre-assembled HVI®power Conductors

In general, one conductor end of the pre-assembled HVI®power Conductor is tted with the relevant

connection element as (Table 3, page 9 and Table 4, page 10). Thus, the head piece is rmly mounted

and a heat shrinkable sleeve is wrapped around it. If required, the second conductor end can be shor-

tened to exactly match the loose connection element to the design of the installation.

When ordering HVI®power Conductors, the conductor / minimum length must be observed / indi-

cated. This information is binding. Conductors cannot be returned since they are tailored to customer

needs (pre-assembled conductor lengths). Pre-assembled HVI®power Conductors are available with

a standard / minimum length of 6 m. Customised conductors can be ordered in 0.5 m steps. The stan-

dard / minimum length of 6 m must be used in combination with a 3.5 m long supporting tube. A mi-

nimum conductor length of 8 m is recommended for a 5 m long supporting tube.

A connection element, heat shrinkable sleeve and hexagon socket wrench are loosely delivered (see

also Table 3).

Special tools (HVI®cutter and HVI®strip 27) should be used to cut HVI®power Conductors to length

/ shorten HVI®power Conductors and the connection element / heat shrinkable sleeve should be at-

tached by means of the relevant connection element (see 5., page 16 ff.).

4.2 Pre-assembled HVI®power Conductors for installation inside the supporting tube

Pre-assembled HVI®power Conductor for installation inside the supporting tube are used to directly

connect the air-termination system of the external lightning protection system to the earth-termination

system, e.g. isolated air-termination system of a mobile phone antenna with HVI®power Conductor

installed inside the supporting tube.

4.6 HVI®power Conductors for installation inside / outside the supporting

tube

The supporting tubes in which the HVI®power Conductors are integrated house an EB element in the

form of a spring element. The head of the supporting tube is mechanically sealed and thus water-proof.

For static reasons, spanning cables over several supporting tubes to split the current is not

possible in every situation! Please contact us for more detailed information.

Different types of supporting tubes are available for installing HVI®power Conductors inside / outside

the supporting tube (see Table 7., page 14 and Table 8., page 15):

5. Assembly of HVI®power Conductors

5.1 Cutting HVI®power Conductors to length / stripping HVI®power Conduc-

tors

The HVI®cutter (cable pliers, Part No. 597 032) can be used to cut HVI®power Conductors to the

required length. Ensure right-angled cut!

The stripping tool (Part No. 597 227) allows the outer semiconductive sheath and the PE insulation of

the HVI®power Conductor to be easily and reliably stripped without damaging the copper conductor

underneath it.

The HVI®strip 27 tool consists of a handle and an exchangeable stripping insert. This HVI®strip 27

stripping insert (Part No. 597 127) can be reordered individually. The stripping insert is plugged into

the handle without tools via a bayonet coupling. The stripping length can be adjusted in steps of 0.2

mm by means of the knob housed in the handle. The chosen stripping length is visible on the scale of

the handle.

The effective stripping length corresponds to the set length with a tolerance of ± 2 mm (see Fig. 2).

The HVI®strip 27 tool is handled as follows:

ÂSet the stripping length (35 mm) on the tool or check whether the set length is correct.

ÂAttach the stripping insert of the tool to the cut conductor end.

ÂThe sheath is cut / stripped by turning the handle clockwise and applying light pressure by means

of the tool.

5.2 Mounting the head piece / connection element

To mount the head piece / connection element, the insulation of HVI®power Conductors must be

removed by 35 mm.

After removing the insulation, the head piece / connection element is mounted on the conductor ends

of the HVI®power Conductor.

The following steps must be observed (see also Fig. 3):

ÂPosition the head piece / connection element above the HVI®power Conductors and turn it clock-

wise onto the relevant conductor end as far as it will go. To this end, an open-end wrench (wrench

size 19) can be used at the wrench contact surface of the head piece / connection element.

ÂTighten the two threaded pins using a tightening torque of 5 Nm. Thus, the copper conductor of the

HVI®power Conductors is safely electrically connected (capable of carrying lightning currents).

5.3 Wrapping a heat shrinkable sleeve around the head piece / connection

element

Applying heat shrinkable sleeves

After mounting the head piece / connection element to the HVI®power Conductor, a heat shrinkable

sleeve must be wrapped around the relevant mounting areas to protect them from mechanical, en-

vironmental or chemical inuences. The connection set includes two heat shrinkable sleeves.

The following must be observed when wrapping a heat shrinkable sleeve around the head

piece / connection element:

ÂThe indicated shrinking area between the head piece / connection element and the

HVI®power Conductor must be observed (Fig. 4).

ÂThe heat shrinkable sleeve is applied between the front shrinking area of the relevant head piece /

connection element and the HVI®power Conductor. The heat shrinkable sleeves must ush with

the shrinking area. If required, they must be repositioned during the shrinking on process.

ÂThe specied shrinking temperature of max. 150 °C must be observed!

ÂThe shrinking temperatures in the shrinking area of the HVI®power Conductor must not be too

high. In case of excessive shrinking temperatures, the semiconductive sheath of the HVI®power

Conductor can be damaged or destroyed and the function of the HVI®power Conductor may not

be ensured any more.

ÂThe heat shrinkable sleeve must not trap air or form bubbles!

6. Installation

6.1 Installing HVI®power Conductors in the supporting tube

Before installing the supporting tube, insert and x the head piece of the pre-assembled HVI®power

Conductor into the supporting tube and x it (see also page Figure 5., page 20).

The following steps must be observed:

ÂUnscrew the locking screw of the head piece (M8 x 25 mm) at the head of the supporting tube.

ÂInsert the HVI®power Conductor from below into the supporting tube. To this end, the compressive

strength of the integrated EB spring element must be overcome. The conductor can be inserted and

removed several times. To contact the head piece, insert the HVI®power Conductor into the sup-

porting tube as far as it will go and hold it there.

ÂFirmly tighten the locking screw (M8 x 25 mm) again using a tightening torque of 15 Nm. This en-

sures that the head piece is xed in the supporting tube and that is electrically connected (capable

of carrying lightning currents). Make sure that there is a sufcient distance (about 7 mm) between

the screw head and the supporting tube after tightening the locking screw. The adhesive coating

of the screw only hardens after about 5 minutes so that the screw can be correctly positioned and

tightened during this period. After hardening of the adhesive coating, the screw must be replaced by

a new one when the screw is removed.

ÂCheck whether the HVI®power Conductor is properly xed in the supporting tube (see Fig. 5).

Proper installation can be veried by slightly pulling the conductor at the point where it leaves the

supporting tube.

ÂThe relevant air-termination tip or rod must be installed before or after the supporting tube has been

installed depending on the conguration of the installation.

ÂInsert the air-termination tip or rod from above into the head of the supporting tube and tighten the

two locking screws (M8 x 16 mm / M8 x 10 mm) using a tightening torque of 15 Nm.
