30kV Epoxy-Cast Potential Transformers
About the Product
The EPF-30SA and EPF-30SB indoor-use potential transformers, designed for a 36kV (max.) power system and insulated with Araldite® epoxy resin, have a high insulation level and superior moisture resistance. In addition, they have passed type testing and environmental testing according to IEC standards and can perform under the temperature condition of -45℃～65℃.
The EPF-30SA and EPF-30SB medium-voltage potential transformers have been a preferred choice of major corporations of numerous countries.
