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.

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).

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.

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.

The extensive variety of related electrical and electronic products supplied by CIC includes LV & MV reactors and motor-starting autotransformers, electric vehicle chargers, distribution panel components, load-break switches, LED displays, power supplies, electronic power transformers, power converters, battery chargers, power banks, PCB, and others.

In Taiwan, CIC is an agent for the measuring instruments by the Fluke and Amprobe brands and is the sole agent for several brands of electrical products, including lightning protection devices (i.e. ESE lightning conductors, lightning monitors, and other accessories), power fuses, surge protection devices, and power factor correction capacitors.

In 2003, CIC established Advanced Electricity Lab (AEL) in Taoyuan, Taiwan, for the purpose of performing reliable electrical testing according to various national and international standards such as IEC, IEEE/ANSI, CNS, etc., both for CIC's own products and for the testing needs of other manufacturers. Since 2003, the laboratory has received accreditation by the Taiwan Accreditation Foundation (TAF), a member of the International Laboratory Accreditation Cooperation (ILAC) and a signatory to the ILAC Mutual Recognition Arrangement (ILAC MRA).

Dedicated to the precision and quality of its products, CIC has been certified to ISO 9001, a standard for quality management systems. CIC is also certified to ISO 14001, an environmental certification.

A well-qualified and accredited electrical manufacturer with decades of experience, CIC is committed to deliver electrical products of the greatest reliability, including indoor and outdoor current transformers, voltage transformers (potential transformers), distribution transformers, and more. CIC’s resourceful and innovative engineering and design team are always happy to meet the specific needs of customers by working towards a perfect solution for their electrical projects. Customization, ingenuity, flexibility, adaptability, and dependability are CIC’s strengths as an OEM/ODM service provider, which is why numerous major corporations worldwide have chosen to establish and maintain successful partnerships with CIC in their electrical projects.
