What is a cold shrink Tube?

 Cold shrink tube is a tubing that shrinks in normal temperatures, so there is no need a special heat gun or other heat tools. It's supplied on a removable core in a pre-stretched shape. The inner core is removed during installation, allowing the tubing to narrow down around the cables, allowing a tight and compact installation.

 With cold shrink tube, it's easy to insulate wires, connections, repair wires, and bundle wires together. Although it has the same functions as heat shrink tubing, cold shrink tube should be considered when the environment is potentially explosive or flammable and safety is a concern. It's also suitable for limited spaces that you may encounter in many industrial applications.

Where Would I Use Cold shrink tube?

Cold shrink tubing is a good alternative to heat shrink tubing in certain environmental conditions. You can use cold shrink tubing to connect joints in field installations, or in cable trenches in hazardous environments where there may be contact with oils, gases, chemicals, or in confined spaces where flammable gases are an issue. Since you don't need to use a flame (such as a heat gun) to shrink cold shrink tubing, it won't overheat or crack like regular heat shrink tubing, which could cause further complications with the cables you're connecting.

Cold shrink tube is very useful when environmental factors play a role in your application. With its ease of installation, it's a great alternative to heat shrink tubing. It also covers a wide range of cables and conductor types, including connectors.

When choosing the size of cold shrink tube, you will want the outside diameter of the cable to be at a midpoint between the recommended minimum/maximum ranges of the cold shrink tube.
