Product Introduction
Dry-type Air Core Reactor
Product Introduction
When you're dealing with high-voltage power systems, you need equipment that delivers unwavering reliability. Our Dry-type Air Core Reactor is engineered specifically for your critical power transmission and distribution needs. This advanced inductive component features aluminum or copper windings encapsulated in epoxy-resin-impregnated fiberglass, with air serving as the magnetic medium instead of traditional iron cores. Connected in parallel in 500kV, 220kV, and 110kV substation low-voltage sides, it's designed for long-distance transmission line capacitive reactive compensation, ensuring your transmission and distribution system maintains optimal voltage stability. You'll appreciate how this technology eliminates magnetic saturation risks while providing perfectly linear voltage-current characteristics, even during extreme fault conditions.

Main Features and Advantages
Linear Performance Under All Conditions
Your reactor maintains constant inductance even during massive fault currents. The air core design prevents magnetic saturation, ensuring predictable performance when you need it most.
Zero Fire Risk Operation
Without insulating oil, you eliminate fire hazards and environmental contamination risks. This makes our reactor perfect for urban substations and environmentally sensitive installations.
Minimal Maintenance Requirements
The solid-state construction means you'll spend less time and money on maintenance. No oil sampling, seal replacements, or core degradation concerns.
Superior Mechanical Strength
Epoxy-impregnated fiberglass encapsulation provides excellent resistance to electromechanical forces during grid faults.
Compact Design
Space-efficient construction allows for flexible installation in various substation configurations.
Practical Applications
Current Limiting Applications
Install our reactors in series with transmission lines to limit fault currents to safe levels for your circuit breakers. This is especially valuable during grid expansions where fault levels exceed legacy equipment ratings.
Reactive Power Compensation
Deploy in Static Var Compensators (SVC) and HVDC converter stations to control reactive power flow and compensate for the Ferranti effect on long transmission lines.
Harmonic Filtering Systems
Use in conjunction with capacitor banks at wind farms or heavy industrial plants to filter dangerous harmonics generated by power electronics, protecting your grid from power quality issues.
FACTS Applications
Perfect for flexible AC transmission systems where rapid switching and high-frequency handling without hysteresis losses are crucial.
How It Works
The Dry-type Air Core Reactor operates on electromagnetic induction principles. When AC current flows through the copper or aluminum windings, it creates a magnetic field in the surrounding air. Unlike iron-core reactors, the absence of ferromagnetic materials ensures linear inductance characteristics.
The epoxy-resin encapsulation provides both electrical insulation and mechanical protection. Heat generated during operation is dissipated through natural or forced air cooling, maintaining optimal operating temperatures.
During fault conditions, the reactor's linear response prevents dangerous voltage spikes while limiting current to manageable levels for your protective equipment.
