CKSG Series Low Voltage Series Reactor

Our Dry-type Iron Core Series Reactor is essential for low-voltage reactive power compensation cabinets. Connected in series with capacitors, it effectively absorbs high-order harmonics generated by rectifiers and converters, significantly improving voltage quality and system power factor. This robust unit suppresses dangerous inrush currents and switching overvoltages, ensuring the safety of capacitors and other electrical equipment. Ideal for industrial grids with heavy harmonic pollution, it offers a reliable solution for stable power system operation and efficient energy management.

Structural Features

1. Available in three-phase and single-phase dry-type iron-core versions.
2. Iron core: high-quality low-loss imported cold-rolled oriented silicon steel, with stable core column air gaps.
3. Coil: Class F enameled flat copper wire, tightly arranged, no outer insulation, excellent heat dissipation.
4. Coil and core are bonded via preheating → vacuum impregnation → curing with Class H varnish, low noise and high heat resistance.
5. Non-magnetic fasteners for core column, ensuring high quality factor, low temperature rise and good filtering.
6. Exposed parts are corrosion-resistant; lead terminals are cold-pressed copper tube terminals.
7. Small size, light weight, beautiful appearance, comparable to well-known foreign brands.
