For over 60 years, professional electrical workers have trusted 3M for innovative solutions that enhance safety and productivity.
That’s why we invented Cold Shrink technology: a revolutionary alternative to traditional heat shrink cable joints and terminations that can be installed fast and easily, without the need for special equipment or permits.
3M™ Cold Shrink Medium Voltage Cable Accessories.
With faster, easier installation, and the long-term reliability provided by superior environmental sealing, 3M™ Cold Shrink Medium Voltage Cable Accessories can help you achieve improved efficiency and performance, as well as significant cost savings.
Read on to learn more about the proven benefits of Cold Shrink technology from the people who invented it.
Easy installation and reliable performance to terminate indoor and outdoor medium voltage cable.
3M™ Cold Shrink QT-II and QT-III Terminations are pre-stretched track-resistant silicone rubber and Hi-K stress control material delivered on a removable core. Removal of the core (unwind) after positioning the termination allows the product to shrink into position, providing a tight seal.
Cold Shrink silicone joint solutions for power cables of rated voltage 11 to 33kV
3M Separable Connectors are used to terminate single core power cables from 11 to 33kV
Terminations and joints for 66kV applications
3M Cold Shrink high voltage accessories install quickly and easily, helping to reduce potential craft errors.
Once installed, the cold shrink tube creates a dynamic, compressed environmental seal and electrical interface without sealants, adhesive or heat sources.

A cold shrink tube is a polymeric (EPDM or silicone) tube expanded, then held pre-stretched by a core providing the mechanical stabilisation. When the core is removed, the tube shrinks at normal temperature. It does not require any heat compared to Heat Shrink tube and this is why it is called COLD SHRINK.
In 1971, 3M developed the first Cold Shrink Pre-Stretched Tube (PST). Since then 3M developed many different power cable accessories for various voltage classes
Ease of installation for increased reliability of installation:
Larger range of cable cross sections with single product:
Reduced installation time which saves money
Maintenance free high voltage terminations:
Higher interfacial pressure improves electrical performance and reduces the risk of failure
