Air Core Reactors

These MV air-core reactors are single-phase dry-type series reactors which are mainly used together with 12 kV or 24 kV capacitor banks in electrical substations of utility companies. The insulation shell of the product is molded in epoxy resin. To reduce core loss and noise, this type of self-cooling detuned reactor utilizes the air-core design and construction. Besides having excellent insulation and moisture resistance, these air-core reactors can withstand large short-circuit current, are easy to maintain, and offer great durability.


About the Product

  • Instead of using silicon steel lamination iron cores, these detuned reactors utilize the “air core” construction and design, resulting in reduced core loss and reduced noise. The exterior of the series reactor (its insulation shell) is molded in epoxy resin. 
  • In addition to their lower noise level, air-core reactors are characterized by excellent electrical properties such as outstanding insulation and moisture resistance. The air-core design and construction enable the series reactor to withstand large short-circuit current, thereby diminishing maintenance costs, increasing safety, and prolonging the product lifespan. 
  • Since 2002, CIC has been qualified and approved to provide air-core reactors for use with 12/24 kV capacitor banks in electrical substations. 
  • The air-core reactors can be used with an enclosure for outdoor applications.

Product Application Examples

CIC’s Air-Core Reactors (25.5 kV, 180 kVA) installed inside Taipei 101 to work with the 25.5 kV/9000 kVAR capacitor bank in the electrical substation of Taiwan Power Company.
