Product Introduction
High Voltage Linearity Air Core Series Reactor
Product Introduction
Welcome to the future of power system protection and control. Our High Voltage Linearity Air Core Series Reactor is an advanced inductive component designed specifically for electrical power transmission and distribution systems. This innovative reactor utilizes a dry-type structure with aluminum or copper windings encapsulated in epoxy-impregnated fiber glass, ensuring superior performance without the limitations of traditional iron-core reactors. You get consistent inductance values regardless of current magnitude, making it the ideal solution for your critical power system applications.
Unlike conventional reactors, our air core design eliminates magnetic saturation concerns. This means your protection equipment receives reliable impedance characteristics even during extreme fault conditions. The reactor effectively addresses industry challenges including catastrophic protection failures, ferromagnantic resonance risks, and maintenance complexities in substations ranging from 35kV to 800kV.

Main Features and Advantages
Linear Performance You Can Trust
Your system benefits from perfectly linear volt-ampere characteristics. The inductance curve remains flat up to fault current ratings, ensuring predictable impedance for reliable relay protection coordination.
Superior Insulation System
We utilize advanced Class F or H insulation with multiple epoxy resin vacuum impregnation cycles. This provides exceptional dielectric strength and maintains partial discharge levels below 10pC.
Unmatched Mechanical Strength
The windings feature fiberglass reinforcement equivalent to steel tensile strength. Your reactor withstands massive radial and axial forces during short-circuit events without deformation.
Weather-Resistant Design
Our UV-resistant, hydrophobic coating prevents tracking and erosion in outdoor environments. You get reliable performance regardless of weather conditions.
Maintenance-Free Operation
The vertical cooling duct design utilizes natural air convection. No pumps or fans required, reducing your operational costs significantly.
Practical Applications
Short-Circuit Current Limiting
Install our High Voltage Linearity Air Core Series Reactor in series with transmission lines to limit fault currents. This protects your existing circuit breakers during grid expansions where fault levels exceed equipment ratings.
Capacitor Bank Protection
Use with high-voltage shunt capacitor banks to limit inrush transient currents. Your capacitor units stay protected from dielectric breakdown while extending switching device lifespan.
HVDC and SVC Systems
Perfect for High Voltage Direct Current converter stations and Static Var Compensator plants. The reactor provides accurate harmonic filtering without detuning from magnetic saturation.
Harmonic Filtering
Effectively suppress harmonic voltage amplification when connected in series with capacitors. You achieve reduced system waveform distortion and improved power quality.
How It Works
The reactor operates on simple yet effective principles. When you connect our High Voltage Linearity Air Core Series Reactor in your circuit, it provides consistent inductive reactance without magnetic core limitations. The air core design ensures linear inductance characteristics across all operating conditions.
During normal operation, the reactor maintains steady-state impedance. When fault conditions occur, traditional iron-core reactors saturate and lose effectiveness. Our air core design continues providing the designed impedance level, ensuring your protection systems work as intended.
The aluminum or copper windings create the required magnetic field in air rather than ferromagnetic material. This eliminates hysteresis losses and provides superior linearity for precise system tuning.

FAQ
Q: Why choose air core over iron-core reactors?
A: Air core reactors maintain consistent inductance during fault conditions. Iron cores saturate when you need protection most, making air core design essential for reliable current limiting.
Q: What installation considerations are important?
A: The reactor generates significant stray magnetic fields. Keep metal structures and sensitive equipment outside specified clearance distances to prevent induced heating and interference.
Q: How do these reactors handle seismic conditions?
A: Our rigid monolithic structures mount on specialized support insulators. For high seismic zones, we provide cross-bracing and dampeners to prevent resonance issues.
Q: What maintenance is required?
A: These reactors are essentially maintenance-free. Routine inspection includes UV coating checks, insulator cleaning, and terminal connection verification.
Q: Can installation occur indoors?
A: Yes, with proper building design considerations. The structure must account for stray magnetic flux effects on building materials and nearby equipment.
