Top Dry-Type Transformer Models and Applications in 2025

Dry-type transformers are increasingly used in modern power distribution systems due to their safety, energy efficiency, and low maintenance requirements. In 2025, with growing demands for intelligent and eco-friendly power equipment, several new models stand out for their technical performance and wide application range. This article presents the top dry-type transformer models recommended for 2025 and offers insights into their ideal application scenarios.

1. SCB18 Series – Level 1 Energy Efficiency

The SCB18 is a high-performance dry-type transformer that meets GB 20052-2024 Class 1 energy efficiency standards. It features a 30% reduction in no-load losses and 10% in load losses compared to conventional models. With optimized windings, high-grade silicon steel, and a smart temperature control system, the SCB18 ensures reliable, low-loss performance for critical systems.

Ideal for: Data centers, hospitals, and rail transit facilities.

2. SCBH19 Series – Amorphous Core for Renewable Energy

Built with an amorphous alloy core, the SCBH19 achieves very low no-load loss and excellent magnetic permeability, outperforming older models like the SCBH15. It is designed for low-load and intermittent scenarios, making it highly efficient for renewable energy systems. Intelligent monitoring options further enhance its performance over the lifecycle.

Ideal for: Solar farms, wind power stations, and distributed power networks.

3. SCB14 Series – Cost-Effective Level 2 Solution

The SCB14 offers solid energy efficiency at a lower investment. It reduces no-load losses by 15% and load losses by 10% compared to the SCB12. With a modular structure, it is easy to install and maintain, making it suitable for standard industrial and residential projects.

Ideal for: Commercial buildings, residential complexes, and industrial parks.

4. Intelligent Dry-Type Transformers – IoT-Enabled Smart Models

Equipped with IoT sensors and cloud platforms, these transformers support real-time monitoring of voltage, current, temperature, and faults. Remote alerts and predictive maintenance reduce downtime and operational risks. These smart units also provide data analytics for energy optimization.

Ideal for: Smart grids, microgrids, automated manufacturing lines.
