10/20kV Epoxy-Cast Potential Transformers for Indoor Use
Medium-Voltage Potential Transformers
About the Product
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.
