The appliaction principle of cold shrink tube

If we need to use heat shrink tube,it must be heated to a certain temperature(above 70°C). Does the cold shrink tube need to be cooled to make it work?
Some guys joked: Heat shrink tube is roasted with fire and cold shrink tube shouldn't use liquid nitrogen to freeze to cool down.

Actually,there is no need to cool down!The cold shrink tube is also a kind of flexible sleeve.It is expanded to a spiral support core after it is enlarged.When needed,the cold shrink tube is covered on the cable joint or end.When the spiral support core is pulled out,the cold shrinkable tube will shrink quickly like a spring and tightly adhere to the surface of the cable.

Features of cold shrink tube

Cold shrink tubing can provide long-term protection for the product and it performs well in indoor and outdoor environments (including harsh environments).In addition,the rubber material conforms to the characteristics of cable bending and the cold shrink tube can be close to the cable without gaps,which can prevent the entry of moisture to ensure long-term protection of the cable.As an important cable accessory,cold shrinkable tube has the characteristics of high tensile strength,good elasticity, fracture resistance, convenient and quick installation, etc.It is mainly used for the sealing of communication cables and optical cables, as well as for pipeline repair and sealing of other parts.
