Eaton Cooper Power Series Installation Instructions Manual page 6

15, 25, and, 35kV Cleer Bail
Step 1
Install 600A grounding elbow
Install grounding elbow onto Cleer bushing according
● ●
to the instructions included with the Cleer grounding
elbow (MN650056EN).
CLEERBAIL and CLEERCHAIN are required when a
Cleer 4/0 grounding elbow (GE6354) is mated with a
Cleer Insert (LBI635) on a 35kV Tee (DT635) in locations
where available fault currents are in excess of 16kA
RMS symmetrical to 25kA RMS symmetrical . The
CLEERCHAIN and CLEERBAIL work together to securely
hold the grounding elbow on the bushing during a
momentary through fault .
Step 2
Connect CLEERCHAIN with CLEERBAIL
Turn the eyebolt counterclockwise until the back of the
● ●
aluminum cup is seated against the welded steel bar of
the bail. Verify the cup is centered on the back of the
elbow.
CLEERCHAIN consists of 25 links. The final installed
● ●
chain should be as tight as possible. Fewer links of the
supplied chain may be needed for proper installation.
Insert one hook of CLEERBAIL through link #1. (Refer
● ●
to Figure 2).
Using the incorrect number of links can result in serious
damage to equipment or fatal injury .

CLEERCHAIN
Step 3
Install CLEERBAIL onto grounding elbow
Place CLEERBAIL onto the back of the grounding
● ●
elbow, ensuring the cup covers the operating eye of
the grounding elbow.
Pull CLEERCHAIN behind the Tee, so CLEERCHAIN is
● ●
under the Tee apparatus bushing interface. (Refer to
Figure 3).

Step 4
Loop CLEERCHAIN
Pull CLEERCHAIN up and over the Tee apparatus
● ●
bushing interface. CLEERCHAIN should now be
hanging over the Tee apparatus bushing interface, on
the same side as the attached bail hook. (Refer to
Figure 4).

Step 5
Bring CLEERCHAIN around the back
Pull the loose side of CLEERCHAIN under the Tee
● ●
apparatus bushing interface to the opposite side,
creating a full circle of chain around the Tee apparatus
bushing interface. (Refer to Figure 5).
Pull CLEERCHAIN as tight as possible during this
● ●
process.
CLEERCHAIN should be pulled as tight as possible .
There should be no slack on CLEERCHAIN . Failure to do
so could result in serious injury or death .
