Eaton COOPER POWER SERIES User manual

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.
