Stereoscopic Wound Core Transformer

The stereoscopic wound core transformer is an energy-efficient power transformer that innovatively revolutionizes the traditional laminated magnetic circuit structure and three-phase layout of conventional power transformers. This results in optimized product performance, including completely symmetrical three-phase magnetic circuits, significant energy savings, substantially reduced noise, enhanced heat dissipation and overload capacity, as well as a compact structure and smaller size.

The S13–S22 series 10kV stereoscopic wound core transformers are primarily suitable for factories, schools, high-rise buildings, commercial centers, airports, and similar applications, serving as power transmission and distribution equipment in urban grids.

The S13–S22 series stereoscopic wound core distribution transformers are a new type of highly energy-efficient product. Compared with traditional transformers, they offer the following features:

Low Operating Noise

According to the JB/T 10088-2016 noise standard, the S13–S22 series stereoscopic wound core distribution transformers operate with lower noise than conventional laminated core transformers.

Low No-Load Current

Due to the high-quality core material and the unique winding process, the no-load current is significantly reduced.

Three-Phase Balance

The triangular stereoscopic wound core is assembled from three identical single frames, with the three core columns arranged in an equilateral triangle. The magnetic path lengths of the three core columns are equal, and the magnetic circuit is completely symmetrical, ensuring excellent three-phase balance.

Enhanced Short-Circuit Resistance  

Frame components and spacers are distributed around the core, with central iron pressure plates securely fastening the spacers. This ensures uniform and symmetrical force distribution across all three phases. The pressed area of the coils increases by 15.7% compared to planar arrangements. The clamp features a triangular stereoscopic frame structure, welded into a single unit. Thanks to the stability of the triangular configuration, the overall strength is significantly improved, ensuring consistent force distribution across all three phases.
