Installation Of Conventional Downconductors - Lightning Protection International Stormaster ESE 15 Installation Manual

∆
Use cable ties when fixing to round sections, such as pipes, tower legs, masts, etc.
∆
If the HVSC Plus downconductor is to be routed above a false ceiling, ensure that it is fixed
to the underside of the concrete floor slab.
∆
Do not use explosive fastening methods on LPI saddles or HVSC Plus downconductors.

Installation of Conventional Downconductors

In some installations, the use of copper tape or insulated stranded copper cable may be installed
as the downconductor. In such cases, it may be necessary to install multiple downconductors
in compliance with local and/or international standards such as NFC 17-102, AS1768, and
IEC 62305. See the following dot points for further information.
The Stormaster ESE terminal provides a bolt for the lug connection to the lower finial connector
of the mast butt adaptor. All conventional downconductors should be lugged and fixed to the
terminal per Figure 14 on page 24.
The following are recommendations and points that should be considered when installing
conventional downconductors.
∆
For structures made of combustible materials, downconductors must be separated from
the structure by a distance of at least 0.1 m and they must have a cross-sectional area of
100 mm
2
Installation on structures:
∆
Minimum of two downconductors are required, preferably on opposite sides of the
structure
∆
At least one of these downconductors must be a dedicated downconductor per
EN 50164-2 and the other can be the natural components of the structure (i.e., both
downconductors cannot be natural components)
∆
For installations where multiple Stormaster terminals are installed, the requirement for
two downconductors per terminal is waived
Standalone / isolated installation:
∆
Only one downconductor is required
∆
The "structure" may be used if metallic and complies with the requirements for
downconductors
Note: EN 50164-2 has a requirement for copper and aluminium downconductors to have a
cross-sectional area of at least 50 mm
Routing and installation:
∆
Install externally wherever possible. Internal installation requires routing inside a non-
flammable insulating pipe
