Data Sheet
1.0 Product Description
1.1 General
The 3M Industrial Loadbreak 15 kV Bushing Insert
™
threads into a universal bushing well to provide the same
function as an integral loadbreak bushing. Using bushing
inserts makes field installation and replacement possible
and efficient. Bushing inserts and elbow connectors
comprise the essential components of all loadbreak
connections.
The Bushing Insert uses a patented "ALL COPPER
CURRENT PATH," containing only one current transfer
point, within the insert itself. The uncomplicated nature
of the current path design delivers superior, reliable
performance.
An internal hex broach allows for positive torque controlled
installation. Using a torque tool, the bushing insert can be
properly tightened into the bushing well without the fear of
accidentally breaking the bushing well stud.
The exclusive latch indicator ring, located on the
circumference of the bushing's collar, eliminates the
guesswork of loadbreak elbow installation on the bushing
insert. The bright yellow ring provides immediate
feedback to determine if the elbow is properly installed on
the insert. If the yellow ring is completely covered by the
loadbreak elbow, it is fully "latched." If the ring is visible,
the elbow can be installed correctly before any problems
can occur.
The bushing insert meets all the requirements of ANSI/IEEE
Standard 386 and is completely interchangeable with mating
products that also meet ANSI/IEEE Standard 386. When
mated with a comparably rated component, the bushing
insert provides a fully shielded and submersible connection
for loadbreak operation.
1.2 Installation
No special tools are necessary.
The insert can be installed by hand or with the assistance
of a torque tool. Using the hex-broached base (see Figure
2) and a torque tool, consistent installation can be easily
achieved. Refer to Installation Instruction Sheet for details.
