SAFETY
FOR LIFE
Oil Level and Dielectric Strength
Make sure the oil in the tank is at the proper level by
checking the vented dipstick in the head casting.
Replenish any loss with new, dry transformer oil. Refer
to Figures 2 and 3.
If the switch has been stored for any length of time or is
being relocated, check the dielectric strength of the oil in
accordance with ASTM-approved testing procedures.
Physical properties of the oil used in Kyle
®
distribution
switchgear is found in
Reference Data R280-90-1
.
1.
In new equipment, the oil must have a minimum
dielectric strength of 26 kV. If less than 26 kV, filter
the oil to restore its dielectric strength to an accept-
able level.
2.
If the equipment has been in service and is being
relocated, the minimum dielectric strength of the oil
must be at least 22 kV. If less than 22 kV, or if the oil
is contaminated with carbon or sludge, replace the
oil.
3.
Check that the actual settings agree with the section-
alizer nameplate and are correct for the planned
installation.
Lifting the Sectionalizer
Follow all approved safety practices when making hitch-
es and lifting the equipment. Lift the load smoothly, and
do not allow the load to shift.
This unit has two lifting lugs.
Both lugs must be used
when lifting
. Maximum strength is attained with a verti-
cal lift attached to the lugs. Use a spreader bar with a
fixed attachment point for the hook at the load center.
If a sling is used, it must have a fixed attachment point
at the load center. Rig the load so that the sling height is
equal to or greater than the distance between lifting
lugs. See Figure 8.
Mounting the Sectionalizer
Figures 9 and 10 show installation using Kyle mounting
frames. If other mounting means are used, support the
GV sectionalizer at the four 5/8 inch bolt holes in the
mounting rails on the tank. The GW sectionalizer is sup-
ported at the twelve 1/2-13 threaded holes tapped into
the sides of the head casting.
Grounding the Sectionalizer
Make ground connections to the sectionalizer. Refer to
Figures 2 and 3.

INSTALLATION
WARNING:
Do not operate this equipment out
of oil. Oil is the electrical insulating medium with-
in this equipment; operating out of oil will result in
internal flashovers that will damage the equipment
and can cause death or severe personal injury.
G104.2
!
CAUTION:
This equipment relies on oil to pro-
vide electrical insulation between components.
The dielectric strength of the oil must be checked on a
regular basis, as part of the routine maintenance
inspection, to ensure that it is at or above minimum
dielectric requirements. Use of this equipment with
insulating oil that does not meet minimum require-
ments can result in internal flashovers that will dam-
age the equipment and can cause personal injury.
G107.2
!
CAUTION:
Follow all locally approved safety prac-
tices when lifting and mounting the equipment. Use
the lifting lugs provided. Lift the unit smoothly and do
not allow the unit to shift. Improper lifting can result in
equipment damage.
G106.2
WARNING:
Hazardous Voltage. Solidly ground
all equipment. Failure to comply can result in
death, severe personal injury, and equipment damage.
