Maximize Voltage Stability with Air-Core Reactors
Air Core Reactors: The Ultimate Solution for Modern Power Grids
Now it is more critical than ever to maintain power quality against harmonics and voltage surges for global power grids. Traditional iron-core reactors are heavy, requiring complex oil insulation. They bring magnetic saturation risks that may destabilize filtering networks during switching operations. LTECPower’s air-core reactors can deliver you a highly efficient, linear solution for power utilities and heavy industrial substations.

Air-Core Reactor Technology: Zero Maintenance, Maximum Safety
When facing critical limits, especially under extreme short-circuit faults, iron-core reactors quickly saturate, and their filtering ability drops sharply. With an ironless design, our air-core reactors can maintain perfect linear impedance even under maximum short-circuit currents. By reliably limiting massive fault currents, the reactors shield your downstream breakers, switchgear, and high-voltage substation gear. With no tuning drift and core saturation, they can also prevent your harmonic filter networks from detuning, and ensure you have non-stop grid protection and clean power quality.
Environmental compliance and fire safety are non-negotiable in modern power system planning. Featuring an oil-free design, our air-core reactors eliminate the oil leakage risk to cut your expensive oil containment tanks, continuous monitoring gear, and regular fluid testing costs. Built with an advanced fiberglass encapsulation, the reactors are safe for immediate installation in dense indoor factories, urban substations, and environmentally sensitive zones.
Only use top-tier materials and rigorous manufacturing standards, our air-core reactors deliver you reliable performance over 30 years of service. Built with premium epoxy-impregnated fiberglass and reinforced non-magnetic frame, the reactors deliver you extreme physical strength and unmatched insulation. By using the advanced dynamic acoustic simulations, they can deliver you whisper-quiet noise levels throughout their entire lifespan. After strict thermal curing and protective enamel coating, our reactors are covered with heavy-duty finish shields for harsh UV radiation and severe industrial acid rain application, with no need for maintenance.

Proven Air-Core Reactors for Demanding Global Sectors
Engineered to maintain absolute linear impedance and robust fault current control, LTECPower’s air-core reactors are widely applied in modern metallurgy, petrochemical plants, and global renewable energy IPPs, and so on.
Metallurgy and Steel Mills
To eliminate massive mechanical shocks, causing costly plant downtime, LTECPower’s air-core reactors are engineered for electric arc furnaces, ladle furnaces, and rolling mills. With with 100% full-welded aluminum conductors and high-strength epoxy fiberglass, our reactors deliver you current limiting and harmonic filtering with perfectly stable 24/7.
Oil, Gas, and Chemical Plants
The motor starting loops for high-power pumps/compressors and chemical substation networks are high-risk and easy to causing huge inrush currents. Our air-core reactors are 100% oil-free and have non-flammable epoxy insulation to eliminate oil spills and fire hazards. By choking down massive startup current surges, they also stabilize your local grid voltage and protect sensitive downstream electronics.
Renewable Energy and Wind & Solar IPPs
Engineered for substations for utility-scale solar plants and onshore/offshore wind farms, our air-core reactors maintain 100% linear inductance to keep your filter perfectly locked onto target error frequencies. Guaranteed with grid compliance, the reactors ensure you non-stop, precise harmonic filtering 24/7, without fines and disconnections.
Mining, Cement, and Heavy Manufacturing
Applied for conveyor systems, rock crushers, and centralized power distribution centers in heavy industrial plants, our air-core reactors are coated with a premium, thermal-cured anti-UV enamel to withstand the thick mining dust, corrosive marine salt spray, and extreme climates ranging from -45°C up to +50°C.
Urban Mass Transit and Railways
Our air-core reactors are dry type and100% oil-free. They can help completely eliminate underground fire and leakage risks for your subways, light rails, and high-speed railways. Engineered with dynamic acoustic simulations, the reactors minimize electrodynamic vibrations to meet the strict urban noise-control codes.
100% linear protection and eco-friendly, safe, our air-core reactors never suffer from magnetic saturation to ensure you the reliable limiting of massive fault current spikes when your system needs it most.
Yes. The air core reactors naturally generate an external stray magnetic field during operation. So, they need to maintain the specified “magnetic clearance distance” to prevent the stray magnetic field from interacting with nearby metal structures or perimeter fences.
Absolutely. Designed for both indoor and outdoor installations, our air-core reactors can be applied in both harsh outdoor and indoor environments. Built with heavy-duty, weatherproof fiberglass, the reactors can keep all moisture and dust out. Coated with a premium protective enamel, they ensure you long-term UV and corrosion resistance.
Pairing seamlessly with capacitor banks to form a tuned LC circuit, our air-core reactors can contribute to power quality improvement in harmonic filter applications. Never suffering from magnetic saturation, the reactors can stay 100% constant across all current levels to prevent the filter circuit from “detuning.”
Built with heavy-duty solid insulation and 100% oil-free construction, our air-core reactors are solid-state and fluid-free. So they can run reliably for over three decades with unmatched durability.
