Introduction
Eaton’s Cooper Power series 600 A, 15 kV, 25 kV and 35
kV Insulated Standoff Bushing meets the full requirements
of ANSI
®
/IEEE Standard 386
™
— Separable Insulated
Connector Systems, and provides a single deadbreak
interface made of high-quality insulating epoxy material. It
is used in pad-mounted cabinets, underground vaults and
other apparatus to isolate and sectionalize an energized
cable. 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 bracket for attachment of a ground 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.
Special pins ensure firm location of the bushing on the
bracket.
