ERITECH ® 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 ERITECH
® ERICORE
to the structure, while minimizing stress
points on the cable.
Use of a brand of saddles other than
ERITECH can compromise the outer sheath,
creating high stress points which can lead
to flashover, (see figure 10).
t
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 must be
checked by an ERICO
representative to see if the damage will
effect its safe operation.
Securing the Downconductor
Use ERITECH clamps only
Figure 10: Detail shows the need to use ERITECH
Clamps.
Securing of the down-
conductor 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 down-
conductor 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 down-
conductor is especially important for
at least the first 10% of the down-
conductor route from the upper
termination, and for this reason the
downconductor must be secured at
least every 1 m (40 in.).
