High-Voltage Current Transformers by CIC are manufactured using Araldite® UV-resistant cycloaliphatic epoxy resin, renowned for its exceptional electrical and mechanical properties. This series of outdoor or indoor current transformers is available in versatile designs and can be offered with multiple iron cores and various specifications, catering primarily to substations or high power loads. They are commonly used for electricity billing, system monitoring, and protection.

CIC's outdoor high-voltage current transformers are recognized for their excellent design and construction, making them ideal for humid, high-salt, or highly polluted areas, such as island regions or offshore wind power installations. Furthermore, their user-friendly design ensures easy installation and maintenance.

CIC, with the transfer of advanced technology from MWB Messwandler-Bau in Germany, has strengthened its decades-long research, design, and manufacturing capabilities. As the first Taiwanese manufacturer to use epoxy resin as the primary insulation material for instrument transformers, CIC produces a wide range of high-quality and versatile current transformers and voltage transformers. CIC excels in providing custom CTs, VTs (PTs), and ODM/OEM services and are trusted by utility companies, factories, major projects, and construction firms worldwide for metering and distribution projects.
