Hubbell Elbow Arrester

200A, 15kV, 25kV, & 35kV Class

DESCRIPTION

Hubbell Elbow Arresters are designed to provide an
effective overvoltage protection for underground
distribution systems. They will mate with any 200A
loadbreak bushing or accessory that contains the
corresponding operating interface per IEEE Std. 386 and
has a fault close rating of 10kA, symmetrical.

• 15kV Class: 200A 8.3kV (Interface 5)

• 25kV Class: 200A 15.2kV (Interface 7A)

• 35kV Class: 200A, 21.1kV (Interface 7B)

• 35kV Class: 200A, 21.1kV (Interface 8)

Note:

• Read these instructions thoroughly before operating the system.

• Check contents of box to ensure that it is complete and the components are NOT damaged.

• Verify product compatibility to existing system

Important:

The elbow arrester should only be applied to systems where the power frequency voltage seen by the arrester does
not exceed the published maximum continuous operating voltage (MCOV). The nominal voltage rating and the
MCOV are located on each elbow arrester.

The elbow arrester can be installed on energized or de-energized systems. Hubbell Power Systems recommends
installation on de-energized systems whenever possible. Follow the same installation procedures for
de-energized systems.

ENERGIZED SYSTEM INSTALLATION

Preparation:

1. Check the arrester for appropriate voltage rating and the interface for
application

2. Verify system maximum continuous operating voltage does not exceed
the MCOV rating of the arrester.

3. Ensure that there is adequate space to install the arrester and attach the
ground leads without interfering with the arrester or other loadbreak
devises operation.

Grounding:

1. Connect the braided ground lead of the arrester to system ground.

2. Attach a #14 or equivalent CU drain wire to the ground tab on the
arrester.

3. Connect the other end of the drain wire directly to system ground
independent of the braided ground lead.

4. Provide enough slack in both leads for hotstick maneuvering.

Lubrication:

1. Remove protective cap.

2. Keep interfaces clean and dry.

3. Apply a thin, uniform coat of the supplied lubricant (DO NOT
SUBSTITUTE as other lubricants may be harmful) to the operating
interface of the arrester.
Caution – Excess lubricant may prevent the elbow arrester from properly
locking into place.

Connection:

Caution – DO NOT INSTALL BY HAND

1. Remove existing elbow or insulating cap from bushing with a hotstick
tool using proper operating procedures and instructions.

2. Fasten hotstick tool to the operating eye of the elbow arrester until rm.

3. Establish an operating position that will provide rm footing and secure

grasp on the hotstick tool throughout the range of movement required for
the operating sequence.

4. Orient the elbow arrester with the grounded end pointing down.

5. Place elbow arrester operating interface over bushing, with the probe
inserted into the mating part.

6. Turn face away and thrust the elbow arrester forward with a rm, quick

motion to lock the arrester on the mating part. Test for proper locking by
gently pulling on the arrester to ensure a secure connection.

7. Be sure to check all ground leads for proper connections. If a ground
lead becomes disconnected, remove the arrester from the bushing with a
hotstick tool before re-attaching the ground lead.

These instructions do not purport to cover all details or variations in equipment nor to provide for every possible contingency to be
met in connection with installation, operation or maintenance. Should further information be desired or should particular problems

arise which are not covered suciently for the purchaser’s purposes, the matter should be referred to Hubbell Power Systems, Inc.
