Air core reactors are inductive devices used in electrical systems to manage reactive power, limit short-circuit currents, and improve power quality. Unlike iron core reactors, which use a magnetic core made of ferromagnetic material, air core reactors rely on air as the primary magnetic medium.

Air core reactors are valuable components in various electrical applications, particularly where low losses and high-frequency performance are required. Their ability to improve power quality and manage reactive power makes them essential in modern electrical systems, especially in industrial and commercial environments.

Key Features

Construction:
1. Air core reactors consist of coils of wire wound in a cylindrical shape without a ferromagnetic core.

2. The absence of a core eliminates core losses associated with hysteresis and eddy currents, making them more efficient at high frequencies.

Inductance:
The inductance value depends on the number of turns, the coil dimensions, and the spacing between turns. Higher inductance can be achieved by increasing the number of turns.

Cooling:
Air core reactors are naturally cooled by the surrounding air, making them suitable for high-temperature applications.
