SC(B) series 30~2500kVA resin insulated dry-type power transformer
Key Features & Benefits
Oil-Free & Environmentally Responsible Design
At the heart of the epoxy resin dry-type transformer lies its revolutionary oil-free construction, which completely eliminates fire risks and oil leakage issues. Compliant with GB 2536-2011 standards, it releases minimal smoke (density <50) when exposed to flames, significantly enhancing safety in enclosed spaces. This eco-friendly design aligns perfectly with green building initiatives and global sustainability goals, reducing environmental impact while lowering long-term maintenance costs associated with oil handling and disposal.
The transformer features an efficient heat dissipation system combining high-performance aluminum heat sinks and axial fans, delivering exceptional cooling efficiency. This innovative design allows for temporary overloads without overheating, ensuring stable operation during peak power demands. The balance between passive heat dissipation and active forced air cooling optimizes energy usage while maintaining optimal operating temperatures, extending equipment lifespan.
Windings are precision-wound with high-quality copper foil, providing superior mechanical strength and moisture resistance critical for harsh operating conditions. This design ensures uniform current distribution, minimizing hot spots and reducing energy losses. The robust construction also enhances resistance to vibration and electrical stress, resulting in a longer operational lifespan and reduced downtime.
Equipped with an integrated intelligent temperature controller, the low noise dry-type transformer automatically starts and stops cooling fans based on real-time internal temperatures. This smart functionality optimizes energy consumption by activating fans only when necessary, reducing wear and lowering operational expenses. The controller supports RS485 communication, enabling seamless remote monitoring and integration with building management systems for centralized control and predictive maintenance.
The compact dry-type transformer finds extensive use in:
Healthcare facilities (hospitals, clinics) powering elevators, fire safety systems, and medical equipment
Educational institutions (schools, universities) where quiet operation is essential
