One of the most trusted and respected brands in the electronics and electrical power markets, CIC also welcomes requests for OEM/ODM services.

Current Transformers and Voltage Transformers

Instrument Transformers

Current Transformers and Voltage Transformers have been the foundation of CIC’s development. In its early years, CIC relied exclusively on in-house technology to design and manufacture indoor current transformers and voltage transformers (potential transformers). In 1990, in order to extend the range of its products, CIC successfully engineered outdoor current transformers and voltage transformers with technology transferred from Germany’s MWB Messwandler-Bau.

In 2010, to advance its technique in SF6 application, CIC created SF6 insulated voltage transformers specifically for 220 kV and 161 kV gas-insulated switchgears. For more than ten years, CIC has also been able to furnish global customers with current transformers (up to 30000 A ) and voltage transformers for use with generator sets. The primary insulation material in CIC Current Transformers and Voltage Transformers is the Araldite® epoxy resin, known for its reliability. The outdoor models make use of cycloaliphatic epoxy resin - similarly to ensure high-quality insulation.

Resin Insulators

Resin Insulators

In 1990, to better serve the needs of its domestic and international clients, CIC imported Swiss-made equipment for the production of resin insulators, such as bushings, housings, and GIS spacers. This fruitful venture has enabled CIC to provide, for many years, resin-insulated replacement parts to its Japanese market. Another distinguished achievement was a special project in 2010, entrusted by Taiwan Power Company, for whom CIC successfully designed and produced support insulators for installation within 345 kV gas-insulated bus ducts. In the same year, CIC manufactured replacement operation cranks for Taiwan Power Company’s 161 kV gas circuit breakers (GCB).

Distribution Transformers

Distribution Transformers

In 1992, CIC became the first manufacturer in Taiwan to successfully produce a non-ventilated low-potential transformer. This was achieved by placing the transformer in a metal enclosure, followed by insulation with an epoxy resin mixture. The heat dissipation afforded by the solidified epoxy resin mixture and by the surface area of the metal enclosure allowed the transformer to be compact. These transformers also had a reduced noise level and could be installed in a number of different ways. The fire-resistant design further led these products to widely replace the oil-immersed transformers and tape-insulated dry-type transformers that were frequently used in large buildings and shopping centers at the time. The non-ventilated LV transformers have since been enhanced with new features, including temperature monitoring and overload protection, and have become even more widely adopted.

In addition to what has been mentioned, today CIC offers various types of distribution transformers, including pole-mounted transformers, oil-immersed transformers, cast-resin dry-type transformers (CRT), pad-mounted transformers, and more.

Electronic Energy Meters

Electronic Meters

Since 2011, CIC’s electronic product division has been offering numerous types of electronic energy meters, such as keypad, outdoor, RS485 communication, prepaid, and DIN-rail types. The accreditation and certification CIC has received concerning its meter range includes – but not limited to – calibration certificates, ISO certificates for the design and manufacture of electricity meters, and metrology licenses for manufacturing, servicing, and importing energy meters.
