冷收缩管一般是指冷收缩式电缆附件.，冷收缩式电缆附件具有体积小、操作方便、迅速、无需工具、适用范围宽和产品规格少等优点。与热收缩式电缆附件相比，不需用火加热，且在安装以后挪动或弯曲不会像热收缩式电缆附件那样出现附件内部层间脱开的危险（因为冷收缩式电缆附件靠弹性压紧力）。与预制式电缆附件相比，虽然都是靠弹性压紧力来保证内部界面特性，但是它不像预制式电缆附件那样与电缆截面一一对应的规格多哦。
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.
