Low-Voltage Current Transformers (~0.72 kV)
LV Current Transformers (~0.72 kV)
Widely used internationally in revenue and switchboard applications by engineering, construction, and power companies, CIC Current Transformers are the result of over 40 years of manufacturing expertise, combined with technology transferred from Messwandler-Bau (MWB) of Germany.
The primary insulation material for CIC's current 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.
CIC's current transformers, including OEM/ODM products, are type-tested and routine-tested by CIC-owned, TAF-accredited Advanced Electricity Laboratory (TAF, or Taiwan Accreditation Foundation, is a member of ILAC and a signatory to the ILAC MRA).
