Dry‑Type Step‑Up Transformer for Solar & Energy Storage Projects

Overview

The dry‑type step‑up transformer is a cast‑resin voltage‑boosting device for renewable energy systems. It is installed between inverters/PCS and medium‑voltage grid. It raises low‑voltage power to medium‑voltage level to realize long‑distance power transmission. No insulating oil is used, delivering high fire safety and environmental performance for indoor and outdoor installations.

What Is Dry‑Type Step‑Up Transformer

Adopting epoxy resin encapsulated windings, this transformer completes voltage boosting without oil medium. It supports stable power conversion for solar, energy storage and industrial sites. It features excellent overload capability, low noise and low maintenance, meeting strict fire‑protection requirements for modern energy projects.
