A project manager from CIC’s Taipei Head Office Team recently visited a CIC factory in Taoyuan City to inspect a batch of Air-Core Reactors.
These handsome and impressive reactors, 30 in total number, have been specially made for Taiwan Power Company, complete with enclosures for outdoor application. The stainless-steel enclosure boxes are quite heavy – each weighing 754 kg (1,662 lbs.)! Each air-core reactor in its enclosure box, complete with accessories, weighs 1,700 kg (3,748 lbs.)!
An air-core reactor is a type of detuned reactor (or series reactor). What distinguishes an air-core reactor from the others is its “air-core” design, which contributes to lower core loss and reduces noise, when compared with other dry-type reactors that make use of silicon steel lamination iron cores. The “air-core” construction also enables these MV single-phase reactors to withstand large short-circuit current, thereby diminishing maintenance needs, enhancing safety, and making them extra durable.
Air-core reactors are usually employed by utility companies for their electrical substations. CIC has been qualified and approved since 2002 to provide these special reactors for use with 12/24 kV capacitor banks in electrical substations.

11Apr 2023 CIC's Air-Core Reactors & Non-Ventilated Transformers in Taipei 101
24 units of CIC's Air-Core Reactors are used inside Taipei 101 (in the electrical substation of Taiwan Power Company). CIC’s Air-Core Reactors are known for their superior quality and are designed to work in conjunction with 25.5 kV/9000 kVAR capacitor banks. These 25.5 kV / 180 kVA dry-type reactors, with a resin-cast exterior, are low-maintenance and long-lasting. The air-core construction contributes to their low noise level and low core loss. In addition, this type of detuned reactor has excellent insulation and are moisture-resistant.

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.
