    Details
    • Quick installation with versatile one-piece design
    • No torches, heat or special tools required
    • Hi-K stress control
    • Excellent tracking resistance, UV resistance and water-shedding properties
    • Includes everything required to make one single phase termination (except lug)

    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.

    Each kit contains: One 3M™ Hi-K Tracking Resistant Silicone Rubber Termination, two Scotch® Mastic Sealing Strips 2230, and one Instruction Sheet.

    Suggested Applications

    • Terminating solid dielectric Jacketed Concentric Neutral (JCN) and Concentric Neutral (CN) power cables
    • Designed for solid dielectric insulations, such as polyethylene, XLPE and EPR
    • Free-hanging or bracket-mounting arrangements
    • Compact design provides for easier installation in restricted spaces
    • Switchgear, transformer, motor lead, bus and similar connections
    • For outdoor use
