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
