Instructions For Tape Shielded Cable
2.0 Prepare Cable
2.1 Check to be sure cable size fits within kit size range as shown in Table 1.
2.2 Prepare cable using dimensions shown in Figure 1. Refer to Table 2 for semi-con cutback dimension.
BE SURE TO ALLOW FOR DEPTH OF TERMINAL LUG. If necessary to prevent tape shield from
unrolling, hold down edge with a single wrap of 3M™ EMI Copper Foil Shielding Tape 1181.
NOTE: Provide additional exposed conductor distance to account for growth during crimping of ALUMINUM
lugs or connectors as follows:
Aluminum Connector
Growth Allowance
2 - 350
1/4” (6 mm)
400 - 650
1/2" (13 mm)
750–1000
3/4" (19 mm)
NOTE: It is imperative to remove all remnants of the semi-con layer, even if the semi-con layer comes off as one
layer. There should not be any remaining black areas, or particles, on the cable insulation layer.
