The dual coupling termination allows the
ERITECH
® DYNASPHERE air terminal to
connect to two ERITECH ® ERICORE cables,
each complete with upper terminations
and FRP masts. All the rules that nor-
mally apply to a single ERITECH ERICORE
arrangement apply to these two cables
and mast arrangement.
A typical mast arrangement is shown in
Figure 35. The normal u-bolts are used to
fix the FRP masts to the aluminum mast,
and the conductive saddles are used to fix
the ERITECH
® ERICORE to the mast at the
normal interval of at least every 1 meter
(40 in.). Note that the center mast and
the two FRP sections will not be
completely in line when the FRP masts
are correctly spaced.
Depending on the mast height required,
either the 2 meter, or the 4.6 meter, FRP
mast may be used.
Running two or more parallel cables
reduces the voltage rise on each cable
by reducing the current magnitude flow-
ing in each cable. For example, if three
cables were run in parallel, each cable
could be three times the single length.
In practice, however, this technique is
generally only economically viable when
running two cable sections in parallel.
ERICO has developed a special hardware
arrangement to allow this to occur, as
illustrated in Figure 34.
