Distribution Transformers

D11-M Series Single-Phase Oil-Immersed Transformer, Pole Mounted Transformer

Product Overview

In distribution networks with dispersed power supply, single-phase transformers offer significant advantages as distribution transformers. They can reduce the length of low-voltage distribution lines, minimize line losses, and improve power supply quality. Designed with a high-efficiency, energy-saving wound core structure, these transformers feature a pole-mounted suspension installation, compact size, low infrastructure investment, and a reduced low-voltage power supply radius, which can cut low-voltage line losses by over 60%. The fully sealed structure ensures strong overload capacity, high reliability for continuous operation, easy maintenance, and long service life.
