600 A 35 kV class PUSH-OP™
insulated standoff bushing
General
Eaton meets the full requirements of IEEE Std
386™-2006 standard – Separable Insulated
Connector Systems in its Cooper Power™ series
600 A, 35 kV PUSH-OP™ insulated standoff
bushing providing 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 35 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 provides easy installation
of a PUSH-OP connector without any threading
operations. 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 tap. 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.
