Heat shrinkable cable breakouts

Heat shrinkable cable breakouts are made of crosslinked polyolefin and are black in color. Due to the black color, they are UV resistant. In addition, they are halogen-free. They are not flame-retardant or self-extinguishing. 

Our heat shrinkable cable breakouts have an operating temperature of at least -55 °C and up to +110 °C. The full shrink temperature is +110 °C.

The 30 variants we offer can be divided into four groups, namely by the number of cores. Depending on the number of wires or cables into which the cable to be protected is branched, you select the corresponding number of cores. The following numbers of cores are available: 

• 2
• 3
• 4
• 5

Heat shrinkable cable breakouts are used to protect a cable branch-out. When a cable is branched, the point where this occurs is a vulnerable spot. By protecting the branch-out with a heat shrinkable breakout, you can be sure that the branch is well protected against external influences. Because the breakouts contain adhesive, which melts when the breakout is heated during shrinking, the branch is protected against moisture and dust. 

When purchasing a heat shrinkable breakout, determine how many cores you need. The number of cores must correspond to the number of cables or wires into which the cable is branched. Place the breakout over the branch-out and heat it with a hot air gun so that the breakout shrinks. 

In addition to the number of cores, it is important to choose a post-shrink diameter that is slightly smaller than the diameter of the cable. For example, if the cable has a diameter of 13 millimeters, choose a breakout with a post-shrink diameter of 12 millimeters.

Also note that heat shrinkable cable breakouts shrink by up to 10% in length. This may affect how well the breakout fits over the branch.
