Key Features:
Dry-Type Air-Core Design:
LTEC air-core reactors utilize a dry-type air-core design, providing higher grid stability and power quality while eliminating the environmental risks associated with traditional oil-filled equipment.
Precision Winding Technology:
Using high-grade aluminum (or optional copper) conductors and precise winding technology, insulated with high-temperature polyester film, to achieve excellent conductivity.
Maintenance-Free & Eco-Friendly:
By replacing traditional oil-filled designs, our air-core reactors avoid soil contamination risks, reduce operating costs, and are more environmentally friendly and compliant.
Superior Mechanical Strength:
Air-core reactors feature a mechanically rigid encapsulated winding design, ensuring superior short-circuit resistance and seismic durability.
Compact & Flexible Installation:
Vertical, horizontal, or stacked designs, with a small footprint, facilitate optimal space utilization in your power plant and extend equipment lifespan.
Applications of Air Core Reactors
Power Systems: Harmonic filtering, reactive power compensation, fault current limiting.
Renewable Energy: Solar/wind farms for grid stability.
Industrial: Motor starting, arc suppression, and UPS systems.
High-Frequency Circuits: RF and telecom applications.
