air core series reactor

Air Core Series Reactor - Professional Power Protection Solutions

Product Introduction

When your power system faces challenging fault currents and harmonic distortions, you need reliable protection that won't fail when it matters most. Our air core series reactor delivers exceptional current limiting capabilities without the magnetic saturation issues of traditional iron-core designs. This specialized dry-type inductor uses advanced non-magnetic materials and precision engineering to maintain constant inductance regardless of current magnitude. You can trust our reactor to protect your valuable equipment during short-circuit events while ensuring optimal power quality in your electrical network.

Technical Specifications

Main Features and Advantages

Linear Performance Under All Conditions

Unlike iron-core alternatives, our reactor maintains perfect linearity during fault conditions. You get consistent impedance when protection is most critical.

Zero Magnetic Saturation

The air core design eliminates saturation concerns. Your system stays protected even during massive short-circuit events that would compromise traditional reactors.

Superior Harmonic Handling

Advanced copper windings and epoxy-impregnated fiberglass construction handle harmonic currents without overheating or performance degradation.

Maintenance-Free Operation

No moving parts or magnetic materials mean minimal maintenance requirements. You save on operational costs over the reactor's lifetime.

High Altitude Performance

Our designs work effectively up to 4000m elevation, making them suitable for challenging geographical installations.

Practical Applications

Capacitor Bank Protection

Install our reactor in series with your HV capacitor banks. It suppresses dangerous inrush currents during switching and prevents harmonic resonance that could damage expensive capacitor units.

Substation Fault Current Limiting

Place the reactor strategically in your transmission lines or feeders. During downstream faults, it limits current to levels your circuit breakers can safely interrupt.

HVDC and SVC Systems

Use our reactor in Static Var Compensators and High-Voltage Direct Current systems for harmonic filtering and voltage smoothing in these demanding applications.

Industrial Harmonic Filtering

In heavy industrial environments like steel mills, our air core series reactor works with capacitors to create effective harmonic filters for non-linear loads.

How It Works

The reactor operates on fundamental electromagnetic principles. When current flows through the copper windings, it creates a magnetic field in the air core. This produces inductive reactance that opposes current changes.

During normal operation, the reactor allows rated current to pass with minimal voltage drop. When fault conditions occur, the reactor's impedance immediately limits current rise, protecting downstream equipment.

The air core design ensures the magnetic field remains linear regardless of current magnitude. This means consistent protection performance from light load to maximum fault conditions.

FAQ

Q: What's the difference between air core and iron core reactors?

A: Air core reactors maintain linear inductance under all current levels, while iron core types saturate during high currents, reducing their effectiveness when protection is most needed.

Q: Can you customize inductance values?

A: Yes, we design reactors with specific inductance values based on your system requirements and protection coordination studies.

Q: What maintenance is required?

A: Minimal maintenance is needed. Annual visual inspections and periodic electrical testing are typically sufficient.

Q: How do I select the right reactor for my application?

A: Our engineers can help you calculate the required inductance based on your system parameters and protection requirements.

Q: What delivery times can you offer?

A: Standard products typically ship within 4-6 weeks. Custom designs may require 8-12 weeks depending on specifications.
