China Low Voltage Reactor Suppliers - Factory Direct Inductive Devices for Power Quality Improvement

Low-voltage reactors are essential inductive devices utilized in low-voltage power distribution systems in China. These reactors are designed to be connected in series with low-voltage capacitors, effectively suppressing harmonic amplification and limiting inrush current. This not only enhances voltage quality but also safeguards the capacitors from potential damage. Available in both series and parallel configurations, low-voltage reactors are a critical component of reactive power compensation devices. As a leading factory among local suppliers, we guarantee high-quality low-voltage reactors to meet your power distribution needs efficiently

Product Description

Main Features
Structure and Materials: Typically employs a dry-core structure. The core is made of high-quality, low-loss silicon steel sheets, and the coil is wound with enameled flat wire using F- or H-grade insulation materials.
Manufacturing Process: Vacuum impregnation and heat curing processes ensure a strong bond between the coil and core, reducing noise, improving heat resistance, and providing excellent heat dissipation.
Other Key Features:
  • Fasteners are made of non-magnetic materials, improving the quality factor.
  • Equipped with over-temperature protection (triggers at 170°C to 180°C).
  • Vacuum overpressure injected insulation material for enhanced reliability.
Main Functions
Suppressing Harmonic Amplification: Prevents resonance in systems with nonlinear loads (converters/rectifiers) by connecting the reactor in series, effectively suppressing harmonic pollution.
Limiting Inrush Current: Protects capacitor banks by limiting the significant inrush current generated during connection and disconnection operations.
Improving Power Quality: Stabilizes voltage waveforms and improves the system's power factor by compensating for reactive power.

Frequently Asked Questions
What is a CKSG low-voltage series reactor?
It is a dry-core inductive component connected in series with capacitor banks to suppress harmonics, limit inrush current, and improve power quality in distribution systems.
What insulation materials are used?
The reactors use F- or H-grade insulation materials for the coils and are treated with vacuum overpressure injected insulation for maximum reliability.
How does it suppress harmonics?
By shifting the resonant frequency of the capacitor circuit, the reactor prevents the amplification of harmonics generated by nonlinear loads like frequency converters.
Is there built-in thermal protection?
Yes, many models feature integrated over-temperature protection that activates between 170°C and 180°C to ensure system safety.
Why use non-magnetic fasteners?
Non-magnetic fasteners prevent additional magnetic losses in the core, maintaining a high quality factor (Q factor) and better efficiency.
Where are these reactors typically installed?
They are commonly found in electrified railways, metallurgical plants, chemical facilities, and petroleum refineries where power factor correction is needed.
