As a pioneer in China's power transformer industry, we have specialized in the R&D and manufacturing of power transformer equipment for decades, and established industry standards with core technologies.
The 10kV class S13-M.RL series represents the pinnacle of efficiency and reliability in distribution transformer technology. Featuring an innovative three-dimensional, continuously wound core design, this transformer achieves a significant reduction in core losses and operating noise compared to traditional laminated core units. Its superior magnetic performance and mechanical strength make it an ideal, eco-friendly choice for utility networks, commercial complexes, and industrial applications where low life-cycle cost and minimal environmental impact are critical. The S13-M.RL series is engineered to deliver exceptional value and dependable performance throughout its extended service life.
Key Features
3D Tridimensional Wound Core Technology：The core consists of three identical single frames in a symmetrical 3D structure, creating a seamless magnetic path that significantly reduces no-load current and hysteresis losses.
Exceptional Energy Efficiency：Benefiting from continuously wound silicon steel and an optimized magnetic path, this series achieves ultra-low no-load and load losses, exceeding the Chinese National Standard S13 efficiency class.
Significant Noise Reduction：The perfectly symmetrical three-phase magnetic path drastically reduces core vibration. Its compact mechanical structure ensures operation noise is 10-20 dB lower than conventional transformers, ideal for noise-sensitive areas.
Enhanced Mechanical & Electrical Stability：The 3D structure provides great mechanical integrity, offering excellent short-circuit resistance, shock withstand, and seismic performance. The uniformly pressed windings further enhance overall reliability.
Eco-Friendly and Long Service Life：Higher efficiency translates to reduced energy waste and lower carbon emissions. High-quality materials and robust design ensure a longer service life, making it a reliable green power solution.
