Rack
All-welded
all-aluminum 3 inch web channel construction for
cantilever pole mounting on standard utility class
wooden poles. Standard ground study for
#6 soft drawn copper. Three capacitor and
6 capacitor rack designs available. Six
cell racks available on units supplied with three
cells to allow for expansion.
Capacitors
The
capacitors are a low loss, all-film, double bushing,
design with ANSI gray stainless steel tanks.
Capacitors are connected in wye for optional grounding
by customer Capacitors produce rated kvar
at rated voltage and frequency. Capacitors comply
with all applicable NEMA and ANSI/IEEE standards.
Internal discharge resistors reduce residual
voltage in capacitors to less than 50 volts within
5 minutes of de-energiztion. Dielectric fluid
is environmentally friendly, biodegradable, non
PCB with low toxicity.
Control
Package
The pole-top banks can be
supplied with a variety of control options. See
table 1 below for further information.

Switches
Three
single phase, 15kV group operated oil switches
(optional vacuum switches available) are supplied
with the pole-top bank. A rack mounted aluminum
junction box simplifies wiring to the control
box at base of pole.
Control Box
Pad
locking NEMA 3R is supplied as standard for mounting
at base of pole.
Fault
Current Rating
Capacitors
have a 10,000 amp fault current handling capability.
Operating
Temperature
-46F (-40C) to +115F (+46C)
Warranty
5 year replacement on the
rack and 1 year replacement on the capacitors.
Optional extended warranties available on request.

Cross
Arm/Cross Arm Brace
(CC)
An
industry standard cross arm and cross arm brace
can be provide with the capacitor rack for mounting
surge arresters and cutouts as shown in figure
1.
Voltage/Current
Monitor Insulator (VCMI)
This
insulator provides a voltage and current signal
for the optional voltage, power factor, and var
controllers.
Vacuum
Switches
(VS)
Are
a more reliable, maintenance free alternative
to the oil switches that are supplied with the
standard rack. These switches are virtually maintenance
free and are most suitable for banks equipped
with automatic controllers.

Control
Power Transformer
(CPT)
An
outdoor control transformer can be provide to
supply control power to the capacitor switches
and switching controls. Control can also
be provide for voltage sensing required by the
optional voltage, power factor, and var
controllers.
Transient
Inrush Reactors
(TIR)
These
reactors minimize switch wear and transients voltages
and currents resulting from capacitor energization.
Reactors are rated 40 mH. Reactors easily
install on the terminals of the capacitors.
Lightning Arresters
(LA)
Heavy
duty distribution class lightning arresters can
be provide for surge protection of the capacitor
bank and associated components.
