nVent ERICO brand of saddles and
conductive clamps are
recommended for the purpose of securing
the downconductor. These have been
specifically designed and manufactured to
mechanically secure and electrically bond
the nVent ERICO Ericore to the structure,
while minimizing stress points on the cable.
Only use nVent ERICO provided
clamps. Use of an alternative brand
of saddle can compromise the outer sheath,
creating high stress points which can lead to
flashover (see Figure ).
• To seat the terminal correctly in the top
of the FRP mast, any cable slack will
have to be removed from the mast while
also minimizing any stress on the upper
termination sheds (flanges) by twisting
the FRP mast against the terminal for at
least one turn.
If the downconductor is damaged
during installation, it is no longer
usable and must be replaced.
Securing the Downconductor
Securing of the downconductor
not only provides a mechanical
attachment to the structure, but also an
electro-static connection to the structure
via the semiconductive outer sheath of
the downconductor cable.
It is important that the downconductor is
both physically and electrically secured to
the entire length of the structure to relieve
both physical and electrical stresses
along the downconductors’ length.
The electrical bonding of the
downconductor is especially important
for at least the first % of the
downconductor route from the upper
termination, and for this reason the
downconductor must be secured at least
every m ( in.). Roof penetrations are
acceptable within the first % of the
downconductor route.
