recloser can be installed in
different ways — within a substation frame, a pole-
mounting frame or a structure provided by the
customer. Regardless of the chosen method, it is
important to ensure that the recloser is mounted
vertically, level and securely fastened. Follow your
company guidelines and relevant codes to
determine the appropriate height for the recloser,
secure the frame to the pole or foundation and
make the necessary connections.
Please note that it is acceptable to loop extra
control cable, but do not pass any conductors
or grounds through the control cable loop. It is
generally recommended to keep the ground away
from the control cable as much as possible to
prevent any induced voltage in the control cable
due to grounding.
The bend radius of the control cable is 7 inches.
Do not bend the cable more than a radius
of 7 inches to avoid damage to the cable.
The H1 and H2 terminal spade connectors
are equipped with 3/8" silicon bronze
fasteners, which must be torqued to between
15–20 ft-lbs.
8.1 Mounting
The recloser can be shipped with three different
mounting options — a pole-mounting frame, a
substation frame or no frame at all. The following
section outlines the recommended installation
procedure for each type of frame.
8.1.1 Pole mounting
To install single-tank recloser pole frames (see
figures 15 and Figure 17), follow these steps:
1.
Attach the lifting brackets (see figure 16)
to the sides of the recloser according to
the lifting instructions.
2. If the frame is not pre-assembled when
shipped, assemble it on a flat surface
following the provided instructions. Pay
close attention to the drawing, and ensure
that the correct bracket is used to mount
the recloser frame to the pole.
