The CKSC series dry-type iron-core reactor is a core component of reactive power compensation systems. Engineered to work in series with capacitor banks, it effectively optimizes power quality and extends the service life of capacitor banks by suppressing grid harmonics and limiting capacitor energization inrush currents. By accurately tuning the reactance rate (typically 6%, 7%, or 13%), our reactors prevent parallel resonance and protect capacitors from overheating and premature failure. The iron core design provides high linearity and stable inductance even under heavy load conditions, ensuring long-term power quality for industrial facilities.

Q1: How do these reactors protect capacitor banks?
By working in series with capacitor banks, they limit energization inrush currents and prevent parallel resonance. This keeps capacitors from overheating and drastically reduces the risk of premature failure.
Q2: What specific harmonics do these reactors mitigate?
Our CKSC reactors are carefully engineered to effectively target and suppress the 3rd, 5th, and 7th harmonics within modern electrical systems.
Q3: What makes your iron core design reliable under heavy loads?
The iron core provides exceptional linearity, meaning the inductance remains highly stable even when subjected to loads up to 1.8 times the rated current. Combined with Class H VPI insulation, it handles thermal stress effortlessly.
