Air-Core Reactors

The benefits of filling a reactor core with air, rather than a ferromagnetic material are:

• Lower inductance,
• No core loss
• No magnetic saturation, ensuring a continuous and proportional current minimal maintenance and longer equipment life

While the advantages of an air-core reactor outweigh those of its ferromagnetic counterparts, an iron-core reactor is generally less expensive and suitable for applications where the sort time overloads of the reactor are less than three times it continuous current capacity.
