Installation Instructions

2701A4

Loadbreak Bushing Insert

CONTENTS: Loadbreak Bushing Insert, Lubricant, Installation Instructions.

The 2701A4 (1) is designed to provide the apparatus interface for Elastimold25kV class (15.2kVphase--to--ground and 26.3kV
phase--to--phase) loadbreakconnections. The blue interface sleeve provides indicationof fullelbow seating and also provides
vents for improved switching performance. This product is identified by a blue button attached to one grounding tab.

DANGER

All apparatus must be de--energized during installation
or removal of part(s).

All apparatus must be installed and operated in
accordance with individual user, local, and national
work rules. These instructions do not attempt to
provide for every possible contingency.

Do not touch or move energized products.

Excess distortion of the assembled product may result
in its failure.

Inspect parts for damage, rating and compatibility with
mating parts.

FOR MORE INFORMATION ON PARTS, INSTALLATION RATINGS AND COMPATIBILITY, CALL THE NEAREST ELASTIMOLD OFFICE.

This product should be installed only by competent
personnel trained in good safety practices involving
high voltage electrical equipment. These instructions
are not intended as a substitute for adequate training or
experience in such safety practices.

Failure to follow these instructions will result in
damage to the product and serious or fatal injury.

If this product is supplied with a protective shipping
cover(s), remove this shipping cover(s) and replace
with the appropriate HV insulated cap(s) or
connector(s) before submerging or energizing the
circuit.

IMPORTANT

1. Check contents of package to ensure they are complete
and undamaged.

2. Check all components to ensure proper fit with cable
and/or mating products.

STEP 1

Inspect the apparatus bushing well to ensure it is dry and
free from all contaminants. Remove the protective shipping
cover from the bushing insert. Lubricate the bushing well
interface area of the bushing insert with the supplied
lubricant or ELASTIMOLD approved lubricants. DO NOT
SUBSTITUTE. Other lubricants may be harmful to this
product and its mating products.

STEP 2 -- ALTERNATE

Place the lubricated portion of the bushing insert in the
apparatus bushing well. Insert 200AT assembly tool in bore
of bushing insert until fully seated. Insert suitable rod
through the eye of the tool and turn in a clockwise direction.
Continue to rotate the eye of the 200AT until it begins to
ratchet signifying the proper assembly torque has been
reached. Remove 200AT from bushing insert.

CAUTION: The use of other tools can damage the bushing
insert. Tighten by hand or with a 200AT only.

WARNING: 200AT should be periodically calibrated to
insure the absolute minimum clockwise torque. A field aged
200AT torque limiter must never be less than 120
inch--pounds to insure a good 200 ampere connection.

STEP 3

Push a length of copper wire (No. 14 AWG (2,5mm2) or
equivalent) through one of the grounding tabs on the
bushinginsert. Make a small loop and twisttight, takingcare
not to damage the grounding tab. Connect free end of
electrostatic grounding wire to the system ground using a
suitable connector.

The electrostatic grounding wire should be installed in such
a manner so as not to contact the bushing interface or
adjacent bushing interfaces or interfere with the placement
of accessories on nearby parking stands.

This step provides assurance that the insulation shield on
the bushing insert is grounded.
