o. Install second bond bar if required.

 

p. Install hose clamps over ends of strain

 

relief bars.

Note:

Rotate hose clamps so heads will not

 

obstruct fill ports on body.

 

q. Overwrap the strain relief hose clamps

 

with DR tape to prevent hose clamp tails

 

from flagging.

 

r. Build outer sheath sealing collars just

 

beyond ends of strain relief bars. Outer

 

sheath sealing collars are one (1) wrap of

 

3/4" (19 mm) B sealing tape completely

 

overwrapped with highly stretched DR

 

tape (white side out).

6.4Position closure for burial on firmly packed earth. Avoid sharp bends or kinks in the cable.

6.5Slightly incline one closure end about 1/2" (13 mm). Properly place supports under the closure for compound filling.

6.6Insert funnel into lower closure fill port. (During filling, air will escape from higher end.)

6.7Mix compound according to instructions.

Note:

Carefully follow health, safety and

 

environmental information on product

 

label or Material Data Sheet for

 

encapsulating compound being used.

6.8Position closure in final position to be buried, then fill closure with compound. Continue mixing and pouring compound until closure is completely filled and trapped air is removed.

6.9Close fill ports with the snap-in caps.

6.10Check for any compound leaks. If leaks are observed, tighten hose clamps and retape as required.

6.11Closure can be buried immediately.

7.0Closure Reentry

7.1Remove hose clamps from closure and end

caps. Remove any tape from end caps.

7.2With a twisting motion, pull end caps from closure and slide down cable.

7.3Grasping closure at one end, slowly separate halves from encapsulant.

7.4Remove spacer web from splice and discard.

DO NOT REUSE THIS SPACER WEB.

7.5Tear cured encapsulant away, as necessary, to access splice.

7.6After completion of repair, place 3M™ Scotchcast™ Spacer Web 4430 around splice and reassemble closure as outlined in Section 6.1 - 6.3. End caps and sleeves can be reused.

Note:

If original end caps are reused, place a

 

small piece of B-sealing tape in slots on

 

inside of caps.

Note:

Be sure that the spacer web 4430 does not

 

block the fill ports.

7.7Fill closure with new compound as outlined in Sections 6.4 - 6.11.
