冷收縮管一般是指冷收縮式電纜附件.，冷收縮式電纜附件具有體積小、操作方便、迅速、無需工具、適用范圍寬和產品規格少等優點。與熱收縮式電纜附件相比，不需用火加熱，且在安裝以后挪動或彎曲不會像熱收縮式電纜附件那樣出現附件內部層間脫開的危險（因為冷收縮式電纜附件靠彈性壓緊力）。與預制式電纜附件相比，雖然都是靠彈性壓緊力來保證內部界面特性，但是它不像預制式電纜附件那樣與電纜截面一一對應的規格多哦。

The advantages of cold shrink tube compared with heat shrink tube

Cold shrink tubing generally refers to cold shrinkable cable accessories. Cold shrinkable cable accessories have the advantages of small size, easy operation, rapidity, no need for special tools, wide application range and less product specifications. Compared to heat-shrinkable cable attachments, it does not require heating by fire, and moving or bending after installation does not present the risk of disconnection of the internal layers of the accessory, as in the case of heat-shrinkable cable attachments (because cold-shrinkable cable attachments are elastically pressed. Tightness). Compared with the prefabricated cable accessories, although the internal interface characteristics are ensured by the elastic pressing force, it is not one-to-one corresponding to the cable cross section like the prefabricated cable accessories, and has many specifications.
