Products Description
The SG Solid Winding Iron Transformer is a high-performance dry-type transformer designed for modern power distribution and industrial control systems.
It adopts solid cast resin winding technology and high-quality grain-oriented silicon steel core, ensuring high mechanical strength, strong overload capacity, and long-term stability under high temperature and humidity.
Manufactured by Weshare, this transformer meets IEC 60076, GB/T 10228, and CE standards, making it an ideal choice for industrial plants, commercial facilities, renewable energy projects, and data centers where safety, efficiency, and maintenance-free operation are top priorities.
Solid Cast Winding Structure
The epoxy resin cast solid winding provides high dielectric strength, superior moisture resistance, and excellent short-circuit performance.
High Efficiency & Energy Saving
Designed with CRGO silicon steel laminations and optimized magnetic flux distribution.
No-load loss: ≤ 1.2 W/kg
Load loss: ≤ 1.8 W/kg
Efficiency: ≥ 98%
