2 Introduction Founded in 1974, CIC specializes in the supply and manufacture of high-quality instrument transformers, also known as current transformers (CT) and potential transformers (PT). Combining its manufacturing expertise of more than 40 years with technology transferred from Messwandler-Bau (MWB) of Germany, CIC consistently produces indoor and outdoor products that are widely used in revenue and switchboard applications by engineering, construction and power companies in the United States, Canada, Russia, Japan, and other countries. The primary insulation material in CIC instrument 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. Type tests and routine tests for CIC instrument transformers are conducted by CIC-owned Advanced Electricity Laboratory (AEL), which has received accreditation from Taiwan Accreditation Foundation (TAF), a member of the International Laboratory Accreditation Cooperation (ILAC). The entire production procedure for CIC s instrument transformers including mold design, product manufacture, type-testing and routine-testing takes place within CIC s streamlined manufacturing plants. This advantage ensures efficiency in product development, shortens product lead time, and reduces production costs. Continually dedicated to precision and superior standards, CIC also welcomes requests for OEM/ODM services. - 1 / IT

Custom specifications are available. ERCT: Extended Range Current Transformer specifications enable the CT to maintain its rated accuracy and burden rating while measuring 1%~150% of its rated current, surpassing the usual metering-class requirement (5%~100%). Other products, as well as detailed drawings, are available upon request. For more information, please contact us or visit our website: Website: global@cic-ltd.com.tw - 3 / IT
