Potential Transformers

Medium-Voltage Potential Transformers (30~36 kV)

Widely used internationally in revenue and switchboard applications by engineering, construction, and power companies, APSC Potential Transformers (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 APSC'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.

APSC's potential transformers, including OEM/ODM products, are type-tested and routine-tested by APSC-owned, TAF-accredited Advanced Electricity Laboratory (TAF, or Taiwan Accreditation Foundation, is a member of ILAC and a signatory to the ILAC MRA).
