TE Raychem CSTOS Cold Shrink Terminations up to 15 kV

TE Connectivity's Class 1A Cold Shrink Terminations (CSTOS) are a one-piece solution for great performance in cold applied terminations for polymeric cables up to 15 kV. We can cross-reference any other manufacturer's part number for you.

The CSTOS offer a reliable, fast and easy-to-install system to ensure trouble-free service. The components are pre-expanded on an easy-to-remove spiral holdout, allowing installation in compact environments on prepared cable. The silicone body is specially formulated for excellent tracking and erosion resistance. The integrated hi-K mastic provides stress relief and eliminates the need for silicone grease. Sealing mastic for the lug end is built into the expanded termination eliminating the need for additional sealing tapes. Shear bolt and compression style terminals and pin connectors are available to provide reliable connection to a variety of conductors.

The CSTOS components have full traceability to raw materials and are in compliance with the IEEE-48 standards.
