⚛️ 1E Class K1 Nuclear Power Cable

Product Description

1E Class K1 Cable is a nuclear-grade safety cable designed for use in nuclear power plants, where the highest level of reliability and safety is required.

It is specifically engineered to maintain functionality under extreme conditions, including radiation exposure, high temperature, humidity, and seismic events.

K1 cables are installed in critical areas where cables must continue to operate during and after a nuclear accident (LOCA – Loss of Coolant Accident), ensuring the safe shutdown and monitoring of the reactor.

Nuclear Cable – Product Feat

1. High Reliability & Safety

Nuclear cables are designed to operate safely under extreme and critical conditions:

  • Excellent electrical insulation performance.

  • Low Smoke Zero Halogen (LSZH) to minimize to toxic gas emission during fire.

  • Superior flame retardant and fire-resistant performance (IEC 60331 / IEC 60332).

  • Long lifespan design (typically ≥ 40 years)

2. Radiation

  • Capable of withstanding high levels of gamma and beta radiation

  • The material has strong anti-aging properties (EPR / XLPE / rubber /special compounds).

  • Maintains stable electrical performance over long-term radiation exposure.

3. High Temperature & Thermal Stability

  • Continuous operating temperature: 90°C to 120°C (customizable upon request)

  • Short-term fire resistance up to 250°C–1000°C

  • Suitable for high-temperature environments such as reactor surroundings and safety systems.

4. Environmental & Mechanical Performance

  • Excellent resistance to moisture, humidity, and chemical corrosion

  • Strong resistance to vibration and mechanical stress

  • Moisture-proof and steam-resistant design for harsh environments

5. Compliance with International Standards
