Raychem NESK-03 Sealing Kit

Raychem NESK-03 Nuclear End Sealing Kit from TE Connectivity is a nuclear‑grade sealing solution designed to environmentally seal cable ends and spare conductors in nuclear power plant installations. As part of TE's Raychem NESK lineup, this kit leverages heat‑shrink technology and materials intended to withstand the radiation levels and elevated temperatures found inside containment buildings, protecting terminations from moisture ingress. NESK kits are pre‑designed to align with type‑tested designs and include all components required for safe installation, simplifying compliance with nuclear safety expectations. TE Connectivity's Raychem nuclear cable accessories emphasize rugged construction, with Raychem heat‑shrink components generally manufactured from heavy‑wall, flame‑retardant, crosslinked polyolefin and precoated with a nuclear‑grade adhesive to deliver reliable sealing performance in harsh environments.
