Medium Voltage Terminations, 5 kV–46 kV
Over 30 years ago, 3M pioneered cold shrink
technology. Since then, field use and laboratory
analysis have repeatedly proven its merits and
reliability. Through constant innovation, we have
refined cold shrink products making them better than
ever. They’re easier to apply and built to withstand
some of the most punishing environmental
conditions. Enhanced performance at a lower
installed cost continues to make 3M the preferred
choice for cold shrink solutions.
3M™ Cold Shrink QT-II and QT-III Terminations are designed using 3M developed track-resistant silicone
rubber and Hi-K stress control material in conjunction with 3M’s unique cold shrink delivery system.
The QT-II and the QT-III terminations are supplied prestretched on a removable core. Removal of the core
(unwind) after positioning the termination allows the product to shrink into position, providing a tight seal.
3M cold shrink terminations offer easy installation and reliable performance when terminating indoor and
outdoor medium voltage cable.
QT-II and QT-III cold shrink silicone rubber is specifically formulated as a high track-resistant material with
hydrophobicity (water repelling action) to virtually ensure a long life expectancy.
These cold shrink terminations are lightweight for either free-hanging or bracket mounting arrangements.
3M offers you two options for choosing a cold shrink termination. The QT-III termination utilizes the latest
technology with built-in Hi-K stress controlling mastic and environmental sealing mastic resulting in a
much more user-friendly application. The QT-II termination offers some of the same advantages as the QT-
III termination but without a few of the time-saving features that the QT-III termination posesses.
All terminations meet or exceed IEEE 48 requirements.
