Instructions for UniShield® Shielded Cable

12.0Prepare Cable

12.1Check to be sure cable size fits within kit size range as shown in Table 1 (page 2).

12.2Prepare cable using dimensions shown in Figure 16, 17 and 18. Refer to Table 4 for dimension [A]. Be sure to

allow for depth of terminal lug.

NOTE: Provide additional exposed conductor distance to account for growth during crimping of ALUMINUM lugs or connectors as follows:

	Aluminum Connector		2 - 350		400 - 650
	Growth Allowance		1/4” (6 mm)			1/2" (13 mm)
Kit Number		Insulation 0.D.		15 kV		25/28 kV		35 kV	Dimension [A]
				AWG / kcmil		AWG / kcmil	AWG / kcmil
		0.83" - 1.21"		4/0 - 300		2/0-3/0	2 - 2/0		13.5"
	7684-S-8	(21,1 - 30,7 mm)		(120 - 150 mm2)		(70 - 95 mm2)	(35 - 70 mm2)		(342,9 mm)
		0.98" - 1.53"		350 - 500		4/0 - 250	3/0 - 4/0		13.0"
		(24,9 - 38,9 mm)		(185 - 240 mm2)		(120 - 150 mm2)	(95 - 120 mm2)		(330,2 mm)
