air cored reactor

Air Cored Reactor - Professional Power System Solutions

When your power system demands reliable current limiting and harmonic filtering, our air cored reactor delivers unmatched performance. These specialized inductors eliminate magnetic saturation concerns while providing consistent, linear operation across all current levels. Your electrical infrastructure deserves the superior reliability that only air core technology can provide. Unlike traditional iron-core alternatives, our reactors maintain constant inductance regardless of fault conditions, ensuring your system protection remains effective when you need it most.

Technical Specifications

Main Features and Advantages

Linear Performance Under All Conditions

Your system gets consistent impedance characteristics because air cannot saturate. This means reliable protection even during severe fault conditions.

Zero Core Losses

Our design eliminates hysteresis and eddy current losses completely. You benefit from higher efficiency and reduced operating costs.

Maintenance-Free Operation

The dry-type construction with epoxy encapsulation means no oil changes or periodic maintenance. Your operational costs stay minimal.

Compact and Lightweight Design

Space constraints are no longer an issue. Our reactors offer superior power-to-size ratios compared to oil-filled alternatives.

Superior Environmental Resistance

Weather-resistant epoxy housing protects against moisture, dust, and chemical exposure. Perfect for challenging industrial environments.

Practical Applications

Substation Current Limiting

Install our air cored reactor in series with transmission feeders. During short-circuit events, the reactor limits fault current to manageable levels, protecting your circuit breakers and preventing busbar damage.

Harmonic Filtering Systems

Combine with capacitor banks in Static Var Compensators (SVC) for precise harmonic elimination. The linear characteristics ensure consistent tuning frequencies across varying load conditions.

Neutral Grounding Applications

Connect between transformer neutrals and ground to control earth fault currents. This protects your expensive transformers while maintaining system stability.

Renewable Energy Integration

Essential for wind and solar farm collector substations where extensive cabling creates high capacitive charging currents requiring compensation.

How It Works

The air cored reactor operates on fundamental electromagnetic principles without magnetic core complications. Current flowing through the carefully designed windings creates a magnetic field that travels through air rather than ferromagnetic material.

This air-path approach delivers two critical advantages. First, air never reaches magnetic saturation, ensuring your reactor maintains constant inductance even during massive fault currents. Second, the absence of magnetic core material eliminates energy losses from hysteresis and eddy currents.

The epoxy-encapsulated windings provide mechanical strength while maintaining electrical isolation. This construction method creates a robust, weather-resistant component suitable for both indoor and outdoor installations.

FAQ

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

A: Air core reactors cannot saturate, providing linear performance under all conditions. Iron core reactors may saturate during high currents, changing their impedance characteristics.

Q: Can your reactors operate at high altitudes?

A: Yes, our high-prototype products meet requirements for installations up to 4000m above sea level with appropriate derating.

Q: What maintenance do these reactors require?

A: Virtually none. The dry-type construction eliminates oil changes and routine maintenance typically required by liquid-filled units.

Q: How do you ensure consistent quality?

A: Every air cored reactor undergoes comprehensive testing including inductance measurement, insulation testing, and mechanical inspection before delivery.
