Tape Shielded Cable

STEP 1 Prepare Cable
1. Check to be sure cable size fits within insualtion range as shown in the Termination Selection Chart, Page 1.
2. Train cable into position and cut to length required for installation.
3. Prepare cable using dimensions shown below. Be sure to allow for depth of terminal lug. To prevent tape shield from
unrolling, hold down edge with a single wrap of the supplied copper foil tape as shown. Provide additional exposed
conductor distance to account for growth during crimping of ALUMINUM lugs or connectors as follows:

Aluminum Lug 2/0--350 400--650 750--1000

STEP 2 Install Ground Braid

1. Using 50% stretch, carefully wrap one (1) band of mastic around the cable jacket 1/4” (6mm) from jacket end as shown.
Position mastic carefully, it also serves as a marker for positioning the termination. Cut mastic flush, do not overlap.
2. Position preformed ground braid with short tail over tape shield and solder block centered over mastic strip. Secure ground
braid to cable jacket using vinyl tape. Press solder block into mastic. See figure below.

3. Using 50% stretch apply a second mastic band over the solder block and previously applied mastic maintaining the 1/4” (6mm)
dimension. Cut flush, do not overlap.
4. Wrap two half--lapped layers of vinyl tape around mastic seal,carefully maintaining the 1/4” (6mm) dimension.
5. Wrap ground braid around cable tape shield one complete wrap, trim excess to prevent overlap and secure in place with
constant force spring. Wrap spring in same direction as ground braid. Cinch (tighten) the spring after wrapping the final
winding. Secure spring with two (2) wraps of vinyl tape.
SPECIAL NOTE FOR CLOTH OR PAPER SEMI--CON INSULATION SHIELD
In cable with cloth or paper semi--conductive shields it is recommended the shield be over wrapped
with one half--lapped layer of highly stretched semi--conductive rubber tape such as Scotcht No. 13.

STEP 3 Install Lug or Connector
1. Check to ensure termination assembly fits over the selected lug. If lug will not fit through the termination core, clean the
insulation and slide termination on cable before installing lug. Do not remove core at this time.
2. Position connector/lug and crimp according to manufacturer’s directions. Do not crimp the last 3/8” to 1/2” of the connector.
Remove excess oxide inhibitor and all sharp crimp flashings and edges following crimping.

3/8” to 1/2” Uncrimped Length

STEP 4 Clean Cable Insulation and Lug Barrel Using Standard Practice
1. Wipe the cable insulation with an approved solvent. Do not allow solvent to touch semi--con insulation shield.
2. If abrasive must be used:
a. Use on insulation only. Do not use abrasive on semi--con insulation shield.
b. Use only aluminum oxide abrasive; grit 120 or finer.
c. Be careful not to reduce the cable insulation diameter below that allowed by the kit.

STEP 5 Install Termination

1. IMPORTANT: A track resistant moisture seal must be made between termination insulator and lug/connector using gray
silicone rubber electrical tape (contained in kit). Wrap a band of silicone tape around the base of the terminal lug.
a. If barrel diameter is equal to or greater than cable primary insulation, the tape band should not exceed 2 layers.
b. If barrel diameter is smaller than the cable primary insulation, use tape strip to form the tape band equal to
insulation diameter, see below.
2. Cover the edge of the semi--con insulation shield with a liberal coating of silicone grease. On this product the silicone
used to fill the step at the semi--con cut off.

3. On lower termination with fold down skirt pull loose end of removable core through top of termination until the core is flush with
bottom of the termination .

4. Slide the termination body onto the cable, align termination with forward edge of mastic seal as shown below. Carefully
begin to remove core while unwinding, counter--clockwise, starting with loose end. Make sure the termination body, not the
core is butted up to the leading edge of the mastic seal, see below. Continue to remove core. Do not push or pull on
