5.0Cable Preparations

5.1Position and secure cables according to the

splice opening for the closure size selected. See closure dimension guide for the maximum splice openings.

5.2Scuff 6" (152 mm) of outer sheaths as shown.

5.3Wrap all scuffed areas with vinyl tape.

Note:

Vinyl tape should be removed from under

 

Shield Bond Connectors when installed.

5.4Remove outer sheath for a splice opening no greater than the maximum splice opening listed for closure size in closure dimension guide.

5.5Remove shield flush with outer sheath.

5.6Clean filled cable for good encapsulant adhesion and sealing.

Note:

Use only 1 (one) sheath connector on each

 

cable for the 2" (50 mm) diameter closures.

b.Trim core wrapper, leaving 3/4" (19 mm).

c.Install insulation sleeve on strain relief bar(s). Trim length if necessary to clear mounting holes.

d.Install one strain relief bar on Shield Bond Connectors (to hold splice opening and provide temporary bond.)

Note:

Branch cables should be bonded according

 

to illustrations. If necessary, shield

 

connector studs may be trimmed to clear

 

cover halves of smaller diameter closures.
