11KV IEC pole mounted transformers-Overhead Distribution Transformers

11KV IEC pole mounted transformers

The single-phase oil-filled pole-mounted distribution transformers are specifically designed for the decentralization distribution network of servicing residential overhead distribution loads of town and countryside. They are also suitable for light and diversified power applications.
The single-phase oil-filled pole-mounted distribution transformers with a rating in the range of 16 kVA to 200 kVA, connected by open bushings suitable for outdoor service and designed to be mounted on the support structures of overhead lines.
