TE Connectivity NPKS-4-41C Nuclear Plant Splice Kit

TE Connectivity's Raychem NPKS-4-41C Nuclear Plant Splice Kit is a four-conductor nuclear‑grade splice assembly designed to join and insulate conductors in Class 1E nuclear power plant circuits. It provides an environmentally sealed and mechanically protected splice insulation system intended for use in accident conditions, resisting moisture ingress and environmental stress in harsh plant environments. As part of TE's Nuclear Plant Kit family (NPKS), it supports splices that must perform under LOCA/HELB scenarios and is qualified according to nuclear equipment qualification practices, with materials tested for long service lives. TE notes that materials used in nuclear products are validated for typical lifetimes of 40 to 60 years at 90°C, reflecting the plant-life design expectations for cable joints. The NPKS-4-41C is one of several NPKS configurations used to provide electrical continuity and environmental sealing for complex cable networks in nuclear facilities, ensuring insulation and protection of conductors in service environments.
