Installation/Operating Instructions.

The 375LR (without test point) and 376LR (with test point) aredesigned to terminate UD cable having concentric neutral and
extruded insulation shielding. The elbow provides an operating interface forconnecting to an Elastimold 35kV class (21.1kV
phase--- to---ground and 36.6kV phase ---to --- phase) 200 ampere loadbreak bushing or accessory device with fault close
rating of 10,000 amperes RMS symmetrical. When other types of UD cable are to be terminated an appropriate Elastimold
cable shield or grounding device must be used.

DANGER

All apparatus must be de--energized during 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
work rules. These instructions do not attempt to
provide for every possible contingency.

Do not touch or move energized products.

“Loadbreak connectors must be operated with a full
insulated “hotstick” type live--line tool.” Consult the
company’s safe work practices for the required
live--line tool length.

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

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

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

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 asubstitute foradequate 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.

3. Check threadsby threading probe into compression lug.
If resistance is encountered priorto fullassembly, check
for damage and replace damaged component.

4. Read entire installation instructions before starting.

5. Have all required tools at hand and maintain cleanliness
throughout the procedure.

CAUTION: Lubricate test point cap and assemble tightly.

A. Unwrap and bind concentric neutral

wires 8--- 1/2” back from end of cable.

B. Remove shield and insulation from

the cable end. Cut squarely taking
care not to nick conductor.

C. Wire brush bare aluminum conductors

and immediately install compression
lug. Rotate to spread inhibitor.

lug for recommended crimp tool
information.) Start crimp at the crimp
line mark. Rotate 180_ each
successive crimp. Carefully wipe
excessive inhibitor from the outside
of the lug and cable.

D. Remove insulation shield as shown.
