3.4Wrap two highly stretched half-lapped layers of electrical grade vinyl tape around Scotch® Mastic Strip 2230, constant force spring and exposed tape shield (Figure 4).

NOTE: Take care not to cover exposed semi-con insulation shield. A minimum of 3/4" (19 mm) must be exposed.

SPECIAL NOTE FOR CLOTH OR PAPER SEMI-CON INSULATION SHIELD

In cables 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 Scotch® Electrical Semi-Conducting Tape 13.

4.0Install Lug or Connector

4.1Check to insure 3M™ Silicone Rubber Termination QT–III termination assembly fits over the selected lug

or connector. If lug or connector (Figure 5) will not fit through the termination core, clean the insulation

(per Step 5.0) and slide termination on cable before installing lug or connector. DO NOT REMOVE CORE

AT THIS TIME.

NOTE: Refer to pages 17-19 for 3M™ Connector and Lug crimping information.

NOTE: For Aluminum Conductors - Thoroughly wire brush conductor strands to remove aluminum oxide layer. Immediately insert conductor into lug or connector barrel as far as it will go.

4.2Position connector or lug and crimp according to manufacturer's directions. Remove excess oxide inhibitor and sharp crimp flashings following crimping.

5.0Clean Cable Insulation and Lug or Connector Barrel Using Standard Practice

5.1Wipe the cable insulation with one of the solvent saturated pads from the 3M™ Cable Cleaning Preparation Kit

CC–2.Do not allow solvent to touch semi-con insulation shield!

5.2If 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, included in the 3M™ Cable Cleaning Preparation Kit CC-2.

c.Be careful not to reduce the cable insulation diameter below that allowed by the kit.
