Cold Shrink

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 in a fraction of the time, without the need for special equipment or permits.

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.

The cool science of cold shrink technology

The cool science of cold shrink technology

Fast and easy one-step installation

  • Enables installation in 1/3 of the time or less compared to heat shrink
  • No special tools or work permits required
  • Easier to install in tight spaces or inclement weather
  • Easy to learn and train

Long-term reliability

  • Dynamic ‘living seal’ expands and contracts with variations in temperature and load on the cable
  • Designed to last the life of the cable while ensuring excellent electrical performance
  • Low failure rates*
    • - 0.067% for Cold Shrink Molded Joints/Splices
    • - 0.022% for Cold Shrink Terminations

Why heat shrink may not be your best choice

Why heat shrink may not be your best choice

More complex installation

  • Performance highly dependent on installer skill
  • Requires torch and hot work permit
  • Increases required time and potentially costs
  • Installation may require shut-down for facilities containing combustible gasses

Reliability concerns

  • Non-integrated design does not allow for factory testing for Medium Voltage Splices
  • Creates a static seal that does not expand or contract with the cable, potentially leading to the creation of voids between the cable accessory and the cable, which may potentially lead to failure
