What Is The Significance Of Removing The Support Bar During The Installation Of Cold Shrink Cable Accessories?

The support bar serves to maintain the Cold Shrink Cable Accessories pre-expanded shape, allowing the accessories to be smoothly fitted into the cable insulation layer at the construction site. When the support strip is removed, the accessory, relying on its elastic material, contracts and fits tightly against the cable's outer surface.

After the support strip is removed, the rubber or silicone rubber body of the accessory releases its rebound force, actively adhering to the cable. Mechanical drawings and installation manuals mention that the cold shrinkage process is completed after the support strip is removed. The removed support strip is made of plastic or nylon and is responsible for maintaining the pre-expanded state until the final installation stage.
