- Classification of cold shrink cable accessories
- 【Brief 】：
Cold shrinkage cable accessories are made of elastomer materials (commonly used silicone rubber and ethylene propylene rubber) by injection vulcanization in the factory, and then expanded, lined with plastic spiral support to form a variety of cable accessories. During field installation, these pre-expanders are sleeved at the end or joint of the treated cable, and the plastic spiral strips (supports) which are internally supported are extracted, and the cable accessories are formed by pressing them on the cable insulation.
- 【Series】：Cold Shrink Tube
- Product description
Cold shrinkable tubes generally refer to cold shrink cable accessories.
In the early stage, the terminal of cold-shrinkable cable was only added insulation with silicone rubber cold-shrinkable parts, and the electric field treatment still used stress cone type or stress band wrapping type.
Nowadays, cold shrinkage stress control tubes are commonly used, and voltage levels range from 10kV to 35kV. Cold shrinkage cable connector, 1 kV class cold shrinkage insulating pipe for enhanced insulation, 10 kV class with internal and external semi-conductive shielding layer connector cold shrinkage insulating parts. The three core cable terminal fork branch adopts cold shrink branch sleeve.
Cold shrinkable cable accessories have the advantages of small size, easy operation, rapid, no special tools, wide application range and less product specifications. Compared with heat-shrinkable cable accessories, it does not need to be heated by fire, and there is no danger that the interior of the accessories will disengage as the heat-shrinkable cable accessories do when they are moved or bent after installation (because cold-shrinkable cable accessories rely on elastic compression). Compared with the prefabricated cable accessories, although they rely on elastic compression to ensure the internal interface characteristics, but it is not like the prefabricated cable accessories and cable section-to-section correspondence, specifications.
It must be pointed out that the prefabricated cable accessories have no tension before they are installed on the cable, and the cold-shrinkable cable accessories are in high tension condition. Therefore, it must be ensured that the cold-shrinkable components should not have obvious permanent deformation or elastic stress relaxation during the storage period, otherwise after they are installed on the cable. It is not guaranteed that there is enough elastic compacting force, so that good interface characteristics can not be guaranteed.
