SC(B)12 Series Three-Phase Resin-Insulated Dry-Type Power Transformer, (10 kV Class)

This product is the SCB12 series resin‑insulated dry‑type transformer, independently developed by our company through the introduction of advanced foreign technologies. Thanks to its epoxy‑resin cast windings, it offers flame retardancy, fire resistance, explosion protection, maintenance‑free operation, and zero environmental impact, while occupying a compact footprint and allowing direct installation at the load center. Its scientifically sound design and meticulous casting process ensure low partial discharge levels, reduced noise, and excellent heat dissipation, complemented by an intelligent temperature controller that connects to a computer via an RS‑485 serial interface for centralized monitoring and control. Owing to these outstanding features, our dry‑type transformers are widely employed in power transmission and distribution systems—such as hotels, airports, high‑rise buildings, commercial centers, and residential complexes—as well as in harsh environments including subways, metallurgical facilities, power plants, ships, and offshore drilling platforms.
