In the world of nuclear power plants full of unknown challenges, the choice of cables is directly related to the safety and stability of the entire system. Today, TST CABLE will deeply explore the unique advantages and application scenarios of two top materials, PEEK cable and PI cable, in nuclear radiation protection, and unveil the mystery behind them.
- Extreme Challenge: TST CABLE PEEK vs PI, who is the real high temperature resistant king?
TST CABLE PEEK cable (polyetheretherketone): an all-round player who is not afraid of high temperature and radiation
Feature highlights:
- High temperature resistance (long-term use temperature 250℃), chemical corrosion resistance, low smoke and halogen-free, flame retardant, and maintain high mechanical strength and electrical insulation performance under extreme conditions.
Core applications:
Nuclear island drive mechanism winding coil: still strong in high radiation environment, ensuring uninterrupted power transmission.
Electrical penetration: connect internal and external equipment, ensure sealing and electrical performance, and pass strict thermal aging tests.
TST CABLE PI cable (polyimide): the ultimate challenger in ultra-wide temperature range
Feature highlights:
- Wider temperature resistance range (-269℃~400℃), better creep resistance than PEEK, especially suitable for environments above 150℃, with low dielectric loss and clean characteristics.
Core applications:
High temperature instrument cable: suitable for signal transmission in high temperature areas of nuclear power plants, such as reactor peripheral monitoring systems.
Radiation-resistant measurement cable: excellent performance in scenarios requiring extreme temperature stability.
- Nuclear radiation protection competition: PEEK vs PI, who can better resist strong enemies?
PEEK cable: nuclear grade K1 certification, “stabilizing force” under high-dose radiation
LOCA test verification: can withstand radiation doses up to 375kGy, suitable for the most stringent environments inside and outside the containment of nuclear power plants.
Applicable level: meets the K1 requirements of nuclear-grade cables, can still maintain functionality after an accident, and can be called the “invisible guardian” of nuclear power plants.
PI cable: K2/K3 grade, focusing on high temperature stability and cleanliness
γ-ray protection capability: Although the specific tolerance dose is not clear, it performs well in high temperature stability and is suitable for the periphery of nuclear power plants or non-accident environments.
Applicable level: More suitable for K2/K3 scenarios, emphasizing high temperature stability rather than extreme radiation protection.
- Comprehensive comparison: PEEK vs PI, each has its own advantages or is it the only one?
Dimension PEEK cable PI cable
Temperature resistance range Long-term 250℃, short-term 260℃ Long-term 400℃, short-term higher
Nuclear radiation level K1 class (high-dose radiation, below 375kGy) K2/K3 class (focusing on high temperature stability)
Core advantages Radiation resistance, LOCA resistance, low smoke and halogen-free Ultra-wide temperature range, creep resistance, cleanliness
Typical applications Electrical penetrations and drive mechanisms inside the nuclear island High-temperature instruments and peripheral monitoring systems
Conclusion: PEEK vs PI, who will lead the safety revolution of future nuclear power plants?
TST CABLE PEEK cable has become the preferred material for high-radiation core areas of nuclear power plants with its excellent radiation resistance and wide application scenarios, especially in accident conditions, it provides a solid guarantee for the reliability of the power system. TST CABLE PI cable, with its ultra-wide temperature adaptability and excellent creep resistance, shows its unique charm in extreme temperature environments and peripheral monitoring scenarios.
However, with the advancement of technology and the research and development of new materials, the future nuclear power plant safety system may usher in more innovative breakthroughs.
