In some installations, the mast may be used
as the downconductor or alternatively, in
short-run installations, conventional cable is
sometimes used. In these cases, a Terminal
Lug Coupling Adaptor will be supplied
to allow a lugged 50 mm
2 (1/0 AWG) or
70 mm 2 (2/0 AWG) (depending on local
minimum standards) cable termination to
the base of the ERITECH
® DYNASPHERE,
(see figure 12).
Use of Mast or Conventional
Cable as the Downconductor
t
For brick and concrete walls or roofs,
use the ERITECH ® brand of stainless steel
saddles. These have two 6 mm ( 1 ⁄
4
in.)
diameter holes on either side and are
suitable for use with masonry anchors.
These saddles can also be used with other
suitable fastenings against wood, fiberglass
and metallic surfaces.
t
When securing externally to round section
structures such as pipes, tower legs,
masts, etc, stainless steel cable ties are
recommended. Ensure that these are
firmly secured.
t
For securing to other structures such as
angle iron, ie: radio towers, structural
beams etc., use CADDY
® brand of beam
clamps and suitable cable clamps from
ERICO.
t
If the downconductor is to be routed
above a false ceiling, ensure that it is
fixed to the underside of the concrete
floor
slab.
t
Use of exothermic fastening methods
on ERITECH brand of saddles is NOT
recommended.
t
Use of CADDY ® ERISTRUT (or other similar
strut system) is recommended where
suitable, (see figure 11).
