600 A 15 and 25 kV class PUSH-OP™
insulated standoff bushing
General
Eaton meets the full requirements of IEEE
Std 386™-2006 standard, Separable Insulated
Connector Systems with its Cooper Power™
series 600 A, 15 and 25 kV insulated PUSH-OP™
standoff bushing.
The bushing 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 and 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 a switchgear, transformer, or other
apparatus. A drain wire lug is provided on the
standoff bracket for attachment of a drain wire
lead 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.
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.
