3.3kV to 6kV Medium-Voltage Epoxy Resin Potential Transformers for Indoor Use.

Widely used internationally in revenue and switchboard applications by engineering, construction, and power companies, CIC Potential Transformers - also known as voltage 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 potential 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 Potential 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).

  • Indoor Epoxy Resin Potential Transformer
    Indoor Epoxy Resin Potential Transformer
    EGP-3DF Series

    Each phase of our EGP-3DF coil is made by a process of one time casting in epoxy resin, which ensures superior quality and a long operating life and each phase is equipped with fuse protection. This model is designed for a non-grounded system with ground fault monitoring and a trip protection function.


  • Indoor Half-Mold Epoxy Resin Potential Transformer
    Indoor Half-Mold Epoxy Resin Potential Transformer
    EP-3SF Series

    Our medium voltage half-mold epoxy resin 3.3KV potential transformer is suitable for use with a 3.3-5.6KV, single phase, 50/60Hz electric power system. This model can support a wide range of MV switchgear with grounding protection. As with all our models, this meets IEC, IEEE, JIS and other national standards. For different application, EPF-3SF2 and EPF-3SF5 model can be used while required burden is below 500VA, and EP-3SFK model can be used while burden is above 500VA. All of these models completed with fuse protection.
