Advanced Core Technology: Our cold-rolled silicon steel laminations with epoxy-laminated glass spacers provide exceptional stability and minimize losses. The segmented core design ensures consistent air gaps and reliable harmonic suppression.
High-Temperature Performance: Class H enamel-coated flat copper windings deliver silent operation and excellent thermal resistance. This means longer service life and reduced maintenance costs for your facility.
Compact Design: The cabinet-compatible design saves valuable space while delivering powerful performance. You can easily integrate these reactors into existing switchgear configurations.
Superior Harmonic Suppression: Different reactance rates target specific harmonic frequencies - 7% for 5th order and above, 14% for 3rd order and above.
Practical Applications
Your industrial operations will benefit from the CKSG Series LV Dry-Type Iron Core Reactor in various scenarios:
Manufacturing Facilities: Perfect for automotive and metallurgy plants using extensive VFDs and welding equipment. The reactor prevents voltage distortion that could damage sensitive automation systems.
Data Centers: Essential for facilities with high concentrations of switch-mode power supplies and UPS systems. It prevents capacitor overload from 3rd harmonic circulation.
Commercial Buildings: Ideal for office complexes and shopping centers where single-phase loads create significant harmonic content.
Renewable Energy Systems: Critical for solar and wind installations where rapid load fluctuations require precise reactive power management.
How It Works
The reactor operates by creating a controlled impedance path that detunes your power system away from resonant frequencies. When connected in series with capacitor banks, it forms an LC circuit that prevents harmful resonance conditions.
During capacitor switching, the reactor limits inrush currents that could damage contactors and other switching equipment. The iron core design provides high inductance while maintaining excellent linearity even during current surges.
The precision-engineered air gaps in the core prevent magnetic saturation, ensuring consistent performance across varying load conditions. This reliability protects your investment in power factor correction equipment.
Manufacturing Excellence
Our manufacturing process ensures exceptional quality and reliability. We use vacuum pressure impregnation (VPI) technology to eliminate moisture and enhance insulation properties. Each reactor undergoes rigorous testing to meet international standards.
The core assembly uses non-magnetic fasteners and undergoes pre-baking and thermal curing processes. This comprehensive treatment bonds the core and windings permanently, ensuring low losses and consistent harmonic suppression throughout the reactor's service life.
Quality control measures include partial discharge testing and linearity verification to guarantee performance specifications are met.

FAQ
What reactance rate should I choose for my application?
Choose 7% reactance for suppressing 5th harmonics and above (most common). Select 14% when your system has significant 3rd harmonic content from single-phase loads.
How do I maintain my dry-type reactor?
Annual inspections are sufficient. Remove dust accumulation to ensure proper cooling and check terminal connections for tightness to prevent hot spots.
Can the reactor provide short-circuit protection?
No, reactors limit current rise rates but don't interrupt faults. You still need appropriate circuit breakers and fuses for protection.
What causes excessive noise in the reactor?
Usually indicates loose core clamping or operation above rated harmonic current specifications. Proper installation and sizing prevent this issue.
How does linearity affect system safety?
High linearity prevents magnetic saturation during current spikes, maintaining the reactor's ability to detune the circuit and prevent dangerous resonance conditions.
