The
cold-shrinkable cable accessories have the advantages of small size, convenient operation, rapid operation, no need for special tools, wide application range and small product specifications.
Compared with heat-shrinkable cable accessories, it does not need to be heated by fire, and after installation, there is no risk of disengagement between the internal layers of the accessories when moved or bent after installation (because the
cold-shrinkable cable accessories rely on elastic compression. tightness). Compared with prefabricated cable accessories, although the elastic pressing force is used to ensure the internal interface characteristics, it does not correspond to the cable section one-to-one like prefabricated cable accessories, and there are many specifications.
It must be pointed out that the components of prefabricated cable accessories are not under tension before being installed on the cable, while the cold-shrinkable cable accessories are under high tension, so it must be ensured that during the storage period, the cold-shrinkable components should not be There is obvious permanent deformation or elastic stress relaxation, otherwise sufficient elastic pressing force cannot be guaranteed after being installed on the cable, so that good interface characteristics cannot be guaranteed.
