3M™ Cold Shrink QT-III Silicone Rubber Terminations are a one-piece, non-skirted silicone rubber termination that comes with factory-applied, pre-positioned Hi-K stress control layers underneath the insulator. Its short installed length is excellent for installations in limited spaces, such as those with motors, starters, switchgear, variable speed drives, transformers and similar connections which often reduce the need to add auxiliary boxes when enclosure space is limited. The 3M™ Cold Shrink QT-III Silicone Rubber Termination 7664-S-8 has a conductor size range for 5 kV: 500-750 kcmil, 8 kV: 350-700 kcmil, 15 kV: 4/0 AWG-500 kcmil, 25/28 kV: 2/0 AWG-250 kcmil and 35 kV: 2-4/0 AWG.
Each kit contains: One 3M™ Hi-K Tracking Resistant Silicone Rubber Termination, two Scotch® Mastic Sealing Strips 2230, and one Instruction Sheet.
