Medium Voltage Cold Shrink
Cable Terminations & Joints up to 33 kV
Since the conception of 3M Cold Shrink more than 30 years ago, 3M Cold Shrink technology has been found to be a safer, more reliable and easier
to install solution for medium and high voltage jointing and terminating versus conventional heat shrink alternatives. It is a preferred solution for power
utilities, private power network operators and electrical specifiers globally.
Medium and High Voltage Cable Accessories
After many years of developing our 3M cold shrink product range, with
our customers’ needs in mind, we are proud to offer contractors a wide
range of time and money saving joints and terminations to fit almost any
application.

Cold Shrink Terminations
Fully Integrated: Quick Term III (QT-III)
This fully integrated premium cable termination offers the greatest simplicity
and flexibility in our range. Our premium QT-III termination covers a wide
range of cable sizes and types as well as accommodating voltages up to
69 kV. Shorter installation length enables this product to fit into a wide range
of boxes, and fewer installation steps reduce the risk of error.

Cold Shrink Terminations
Part Integrated: Quick Term II (QT-II)
Our part integrated Cold Shrink termination offers a viable cost-based
alternative to heat shrink cable terminating technology. Additional process
steps to our QT-III premium range mean that comparative time savings are
less but the benefits of not having to use heat or extra tooling still apply.
This range covers many of the most common cable configurations and size
ranges.
