What Makes Our Overhead Distribution Transformers Stand Out?

You get more than fair a control transformation gadget. Our transformers combine cold-rolled silicon steel or nebulous amalgam centers with precision-engineered windings, guaranteeing steady voltage change from high-voltage conveyance systems down to 400V/220V for end-user consumption.

Core Design Features

Your transformer arrives with carefully chosen materials optimized for your environment. The oil-immersed self-cooling framework keeps up ideal working temperatures indeed when open air conditions reach 40℃. Each unit experiences thorough testing at the National Transformer Quality Supervision and Review Center.

The compact pole-mounted plan spares establishment space and decreases foundation costs. Whether you're working with single-pole or double-pole arrangements, the adaptable mounting alternatives adjust to your location imperatives.
