Main Features and Advantages

Zero Oil Design - Eliminates fire hazards, oil leakage, and environmental contamination risks. You enjoy peace of mind with environmentally safe operation.

Linear Characteristics - Air core construction provides constant reactance during fault conditions and switching surges. No magnetic saturation means reliable performance when you need it most.

Minimal Maintenance - Solid-state construction reduces operational costs significantly. You spend less time on upkeep and more on productive operations.

Compact Footprint - Space-efficient design perfect for urban substations and underground installations where space is premium.

Superior Reliability - Advanced epoxy resin encapsulation protects against moisture, dust, and environmental stresses.

Wide Operating Range - Handles extreme conditions up to 4000m altitude with consistent performance across temperature variations.

Practical Applications

EHV Transmission Systems - Deploy at main transformer tertiary windings for voltage regulation on long transmission lines. Perfect for suppressing power frequency overvoltage during light load conditions.

Static Var Compensators - Essential component in SVC and FACTS systems, providing dynamic reactive power control for industrial applications like electric arc furnaces.

Renewable Energy Integration - Compensates capacitive reactive power from extensive underground cable networks in wind and solar farms, ensuring grid code compliance.

Urban Substations - Ideal for environmentally sensitive areas where oil-filled equipment poses unacceptable risks.

How It Works

The reactor operates on electromagnetic induction principles without magnetic core saturation. When connected to your transmission system, it absorbs capacitive charging currents generated by lightly loaded transmission lines or underground cables.

The concentric aluminum windings create controlled inductance that counteracts line capacitance. Air core design ensures linear volt-ampere characteristics, maintaining stable reactance even during system disturbances. This prevents the Ferranti effect that causes dangerous overvoltages at transmission line receiving ends.
