COOPER POWER
SERIES
600 A 15/25 kV class PUSH-OP®
insulated standoff bushing
General
Eaton's Cooper Power™ series 600 A, 15/25 kV
PUSH-OP® insulated standoff bushing meets the
full requirements of IEEE 386™-2006 standard
— Separable Insulated Connector Systems and
provides a single deadbreak interface made of high
quality insulating epoxy material.
It is used in switchgear, trans­form­ers, and other
apparatus to isolate and sectionalize an energized
cable. Temporary or permanent parking of
energized 600 A 15/25 kV PUSH-OP deadbreak
con­nec­tors is simplified with the use of an
insulated standoff bushing.
The PUSH-OP insulated standoff bushing is
de­signed to be installed in the parking stand
mounted on switch­gear, transformers, or other
apparatus. A drain wire lug is pro­vid­ed on the
standoff bracket for at­tach­ment of a drain wire
to ensure deadfront construction. The bushing
provides a fully shielded, submersible connection
for deadbreak operation.
All standoff bushing brackets have a stainless steel
eyebolt with a brass pressure foot. The bushing
body is bolted to a stainless steel base bracket
using a stainless steel bolt. The bracket and latch
mechanism provide easy installation of a PUSH-OP
connector without any threading operations. The
optional hitch pin locks the latch mechanism in
place for added security.
Installation
A clampstick tool is used to place the standoff
bushing in the parking stand on the front plate of
the apparatus. The PUSH-OP connector is then
installed onto the standoff bushing. Refer to
Service Information S600-65-1 600 A 15/25 and
35 kV Class PUSH-OP Insulated Standoff Bushing
Installation Instructions for complete installation
details on the PUSH-OP insulated standoff
bushing.
