Epoxy Resin Cast Dry-Type Distribution Transformer | 10kV & 20kV Dual Voltage Design
The Epoxy Resin Cast Dry-Type Distribution Transformer is designed to meet the growing demand for safe, efficient, and flexible power distribution systems. When connected to grid voltages of 10kV or 20kV, the transformer’s high-voltage coil windings are adjusted through a conversion device that allows series or parallel configurations. This enables seamless voltage conversion between 10kV and 20kV without changing the output voltage. As a result, a single transformer can operate under two voltage systems (non-simultaneously), reducing repetitive investment while ensuring stable and reliable performance.
Compliance Standards
Designed and tested in accordance with international standards:
IEC 60076-11: Power Transformers – Part 11: Dry-Type Transformers
IEC 60529: Degrees of Protection Provided by Enclosures (IP Code)
