Silicone Cold shrink breakout

Cold Shrink Silicone Rubber Cable Breakout Boots are a series of open-ended molded silicone rubber sealing assemblies that are factory expanded and mounted on removable inner supporting plastic cores. 

They are supplied for field installation in a pre-expanded condition. The supporting cores are removed after the seal has been positioned for installation around the breakout area of a cable. Core removal allows the silicone rubber boot to shrink down to a predetermined diameter, creating an environmental enclosure for individual cable phase legs and overall cable jacket.  


Features:

  • Cold shrink provides a constant radial pressure seal
  • No extra tools needed for installation.
  • No heat shrink tools required, especially suitable for the place where fire is forbidden
  • 24 months self life reliability
  • Excellent moisture resistant for submersible and outdoor applications
  • Suitable as primary insulation for cable termination and cable joints
