The 2702A1 is designed to provide the apparatusinterface and loop feed---thru for Elastimold 25kV class (15.2kV phase--­to --- ground and 26.3kV phase --- to --- phase) loadbrea k connectors.

DANGER

Allapparatusmustbe de--energizedduring installation
or removal of part(s) except for test point caps and
indicators that can be installed and operated
energized.

After installation loadbreak products can be operated
energized per operating instructions. All deadbreak
connectors must be de --energized before operating.

All apparatus must be installed and operated in
accordance with individual user, local, and national

Inspectpartsfor damage,rating and compatibilitywith
mating parts.

This product should be installed only by competent
personnel trained in good safety practices involving
high voltage electrical equipment. These instructions
arenotintendedasasubstituteforadequatetrainingor
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 insure it is complete
and undamaged.

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

STEP 1

When installing a 2702A1 feed--thru insert in a clampable
apparatus bushing well, check the height of the mounting
bolts. Hardware which protrudes more than 1/2” (12mm)
above the top of the apparatus bushing well will prevent the
feed--thru insert from being assembled. If this condition
exists, consult with apparatus manufacturer on proper
method to shorten bolts.

3. Read entire installation instructions before starting.

4. Have all required tools at hand and observe cleanliness
throughout the procedure.

STEP 2

Inspect the apparatus bushing w ell to ensure it is dry and
free from all contaminants. Lubricate the bushing well and
outer well surface and the bushing well interface and cuff
area of the feed---thru insert with the supplied lubricant or
ELASTIMOLDapprovedlubricant. DO NOT SUBSTITUTE.

STEP 3

Place the lubricated portion of the feet--thru insert in the
apparatus bushing well and rotate feed--thru insert
clockwise until fully seated. DO NOT FORCE. Over
tightening may damage threads of bushing well. The
feed--thru insert has been designed with a special 180_
adjustment feature. Feed--thru insert may now be rotated
counter--clockwise up to a half turn to obtain desired
alignment. A definite stopwill be felt at the end of the180_
adjustment range.

STEP 5

Push a length of copper wire, No. 14 AWG (2.5mm@) or
equivalent, through one of the grounding holes on the
feed--thru insert. Make a small loop and twist tightly, taking
care not to damage the conductive shield. Connectfree end
of the wire to thesystem ground using a suitableconnector.

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

This step provides assurance that theconductive shield on
the feed--thru insert is grounded.
