Why Are Highly Elastic Silicone Rubber Materials Used In Cold Shrink Cable Accessories?

Highly elastic silicone rubber can be pre-expanded during manufacturing and assembled onto a removable support core before delivery to the field. During field installation, the silicone rubber naturally shrinks after the support core is removed, forming a laminated interface that tightly fits the cable body. This pre-expansion method simplifies the installation process and reduces reliance on tools and operational skills.

The elasticity of silicone rubber comes from its molecular structure, which exhibits significant ductility and resilience even in low or high temperature environments. This reversible deformation capability between extension and contraction allows Cold Shrink Cable Accessories to maintain a consistent fit with the insulation layer even when the cable undergoes thermal expansion and contraction.
