standoff bushing-Canadian Edition
General
Eaton's Cooper Power™ series 200 A, 25 and
28 kV insulated standoff bushing meets the full
requirements of IEEE Std 386
– Separable Insulated Connector Systems and
provides a single loadbreak interface made of high
quality peroxide-cured EPDM rubber. It is used to
isolate and sectionalize energized cable in padmounted cabinets, underground vaults, and other
apparatus. Temporary or permanent parking of
energized 200 A, 25 kV and 28 kV loadbreak elbow
connectors that conform to IEEE Std 386
standard is simplified with use of the insulated
standoff bushing.
The insulated standoff bushing is designed to
be installed in the parking stand mounted on a
transformer or other apparatus. A grounding lug
is provided on the standoff bushing bracket for
attachment of a drain wire to ensure deadfront
construction. When mated with a comparably rated
product, the insulated standoff bushing provides a
fully-shielded, submersible, separable connector for
energized operation.

The standard insulated standoff bushing has a
stainless steel eyebolt with a brass pressure foot.
The molded peroxide-cured EPDM rubber body
is bolted to a stainless steel base bracket using
a galvanized steel holddown ring. A completely
stainless steel bracket assembly is available for
extremely corrosive environments.
Installation
No special tools are required. A clampstick tool is
used to place the standoff bushing in the parking
stand on the front plate of the apparatus. Refer to
Service Information S500-22-1, 200 A 15, 25, and
