Indoor service transformer EPF series

medium-voltageIECepoxy resin

Widely used for 12~24 kV power systems and insulated with Araldite® epoxy resin, these potential transformers are characterized by superior moisture resistance and excellent electrical properties. Customizable for different standards and requirements. EPF-10B, EPF-20SE, and EPF-20SI potential transformers have been widely used for 12~24 kV power systems. Insulated with Araldite® epoxy resin and characterized by superior moisture resistance and excellent electrical properties, these potential transformers have met with a high level of customer satisfaction in numerous countries. EPF-10B, EPF-20SE, and EPF-20SI potential transformers are known for their durability. In particular, Model EPF-20SE has, as requested by customers, undergone stringent environmental testing (Thermal Cycling Testing), in which the potential transformer withstood 20 temperature cycles (from -40 to +65℃), lasting approximately 240 hours. All three models can be customized to meet the requirements of different standards and specifications. • Cast in Araldite® epoxy resin • Indoor usage • Standard: IEC or IEEE*
