Installation Instructions
3701A3
Loadbreak Bushing Insert
CONTENTS: Loadbreak Bushing Insert, Lubricant (Do Not Substitute), Installation Instructions.
The 3701A3 is designed to provide the apparatus interface for Elastimold 35KV class (21.1kV phase--to--ground and 36.6kV
phase--to--phase) loadbreak connectors. This bushing provides a venting ring for improved switching performance and is
identified by a white button installed on one grounding eye.
DANGER
All apparatus must be de--energized during installation
or removal of part(s). For loadbreak products follow
operating instructions.
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 by hand.
Excess distortion of the assembled product may result
in its failure.
Contact with solvents, transformer oil, motor oil and
similar substances will degrade jacket conductivity
and insulation level if not immediately wiped off.
FOR MORE INFORMATION ON PARTS, INSTALLATION RATINGS AND COMPATIBILITY, CALL THE NEAREST ELASTIMOLD OFFICE.
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
arenot 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 insure they are complete
and undamaged.
2. Check all components to insure proper fit with cable
and/or mating products.
3. Read entire installation instructions before starting.
4. Have all required tools at hand and maintain cleanliness
throughout the procedure.
STEP 1
Inspect the apparatus bushing well to ensure it is dry and free from all contaminants. Remove the protective shipping cap from
the bushing insert. Lubricate the bushing well interface area of the bushing insert with the supplied lubricant or ELASTIMOLD
approved lubricant. DO NOT SUBSTITUTE. Other lubricants may be harmful to this product and its mating products.

STEP 2
Place the lubricated portion of the bushing insert in the
apparatus bushing well. Hand tighten the bushing insert in a
clockwise direction until it bottoms.
STEP 3
Push a length of copper wire, No. 14 AWG (2,5mm@)or
equivalent, through one of the grounding tabs on the
bushing insert. Make a small loop and twist tight, taking care
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.

STEP 4
Thoroughly wipe the bushing interface clean of any contaminants and lubricate with the supplied lubricant. Install the mating
products to the bushing insert following the instructions supplied with the mating products. Complete assembly of an elbow
is indicated by alignment of the end of the elbow cuff with the ground tab of the bushing insert. If the bushing insert
is not to be immediately mated with an elbow connector, insulated cap or grounding elbow connector, replace the
shipping cover. Do not energize or submerge the apparatus with the shipping cap on the bushing insert. This is a
protective cap only which is not insulated or water tight and only intended to keep the bushing surfaces clean during handling
and installation.
