COOPER POWER
SERIES
3010-4515 A 1.2 kV class externally
removable secondary bushing
General
Eaton’s Cooper Power™ series 3010-4515 A
externally removable secondary bushings are used
for connecting cables outside of pad-mounted
transformer tanks to the secondary coil winding
leads inside the tanks. The 3010 A secondary
bushings are offered as inline and 90° internal
spade versions, 4515 A secondary bushings are
offered as inline only. They are designed for use
in transformer oil, Envirotemp™ FR3™ fluid, or an
approved equivalent. They are externally clamped
for sidewall mounting through a 3.06-inch diameter
hole. The bushings are designed for use inside
cubicles only.
All metallic parts of the bushings are tin plated
for more efficient current interchange. The sealing
gasket is contained by the molded body for
controlled compression, ensuring an effective seal.
The bushing clamp is made of an aluminum alloy
to provide strength for maintaining even gasket
pressure under heavy loads. All bushings are
supplied with a threaded support bracket hole on
the end of the external spade.
Installation
Four clamp studs must be welded around the
bushing hole. Install the gasket over the bushing
shank onto the gasket surface. Insert the bushing
through the tank hole and place the bushing
clamp over the welded tank studs. Install a plated
lock washer and nut onto each stud and tighten.
Connect the internal secondary transformer leads
to the internal spade. Refer to Service Catalog
Section S800-16-1 for installation instructions.

Note:
1. Ratings are the maximum current level that can be used with a particular configuration.
2. Ratings are based on maintaining a bushing temperature rise that is no more than 15 degrees
above 85 degree top oil temperature (20 degree ambient) when the bushings are conducting rated
current (IEEE Std C57.12.00™-1993 standard, Section 5.11)
3. Ratings are based on maintaining a bushing absolute temperature below the level that would
damage the insulation system or seal integrity (with top oil temperature in the range of 113-114
degrees absolute) when the bushing is conducting 150% peak load for 24 hours and 191% peak
load for 2 hours. Reference ANSI/IEEE Std C57.92™-1981 standard, Table 3(d).
(All temperature references are in degrees Celsius.)
