Cold Shrink Tube
Cold shrinkable cable accessories are made of elastomer materials (commonly used silicone rubber and ethylene-propylene rubber) injected and vulcanised in the factory, and then expanded and lined with plastic spiral supports to form various components of cable accessories. Field installation, these pre-expanded parts in the treated cable ends or joints, pull out the internal support of the plastic spiral strip (support), pressed on the cable insulation and the composition of the cable accessories. Because it is at room temperature by elastic retraction force, rather than like heat shrinkable cable accessories to be heated by fire shrinkage, so commonly known as cold shrinkable cable accessories. Early cold shrink cable termination head just additional insulation using silicone rubber cold shrink parts, electric field processing is still using stress cone type or stress band wrapping type.
Universal use of cold shrinkage stress control tube, voltage level from 10kv to 35kv. cold shrink cable joints, 1kv level using cold shrink insulation tube as reinforced insulation, 10kv level with internal and external semi-conductive shielding layer of the joints cold shrink insulation parts. Three-core cable terminal bifurcation using cold shrink branch sleeve.
