The significance of thermal stability in power factor correction capacitors

• Function of Thermal Stability

  Jinneng power factor correction capacitors have passed the IEC standard thermal stability test. They are capable of long-term continuous full-load operation at the maximum extreme ambient temperature. The overall temperature rise is well controlled at an extremely low level with a smooth and stable temperature curve, fundamentally eliminating potential safety hazards caused by equipment overheating and abnormal temperature rise.

   

• Technical Explanation

  Adopting an optimized heat dissipation structure together with premium high-temperature resistant insulating filling materials, our capacitors feature superior heat resistance and low heat decay rate.

  With outstanding overall thermal stability, it does not generate excessive heat or age easily during long-term operation under full-frequency and full-load conditions, effectively extending the service life of the power grid reactive power compensation system.

   

• Jinneng Capacitor Thermal Stability Evaluation Result

  All models of our power factor correction capacitors undergo full thermal stability tests strictly in accordance with IEC 60831. When operated continuously for a long time under the standard maximum temperature condition, the shell temperature rise is well controlled with a smooth temperature curve and no abrupt fluctuations.

  After testing, capacitance degradation is far below the standard permissible limit, no breakdown, flashover or open-circuit faults occurred.

   

• Conclusion

  In summary, our power factor correction capacitors have excellent thermal stability performance, remarkable high-temperature resistance, anti-aging performance and superior heat dissipation, which are fully suitable for long-term uninterrupted operation in various harsh working conditions.
